Cost Effective Tapping and Call Recording using the Sangoma T116
Q&A Key

Q: can we use this tapper between BTS and BSC? and get log from Abis interface?
A: Yes. The A-bis interface signaling channels would be defined as HDLC channels in our boards. Your application could then analyze the content of the signaling (we do not provide this part, as we mentioned we provide the raw data to the application.)

Q: So we should use for each E1 link one tapping boards what is solution for multi E1 links is there any merging system ?
A: You need to use 1 tapping box for each T1 or E1 you want to monitor.

Q: Windows how to use with this board
A: We have a Windows driver for the T116. Customers typically use Windows with our TDM APIs. Please go to wiki.sangoma.com for more details.

Q: What’s the servers specs required for large deployment
A: We have benchmarked with a quad core machine (i7) up to 6 T116 in one system.

Q: For windows based logger do we need to use nbe
A: No. NBE is a VoIP gateway, it is not meant to be a logger application.

Q: What was the server specs on which the load test was done for 116
A: I7 machine with 4 GB RAM.

Q: Do we need echo cancellation boards
A: Not required as you are using the boards in Receive mode only.

Q: Sbc
A: I do not understand the question. SBCs could be used for recording and logging buy doing sip forking to a SIP based recording device.

Q: Also on the 3rd case the hardware cost is half ?? No of e1
A: Yes. That is the reason for the T116. It can be set up in Rx mode only.

Q: could it  provide again wiki link?
A: Here is wiki page for the T116: http://wiki.sangoma.com/t116-16-port-t1-e1-j1-tapping-board

Q: how is synchronize each RX time slots on each frame? Have to set separated setting of clock resource on each port?
A: No need for separate clocking.

Q: Can you confirm that TAP box will not cause any degradation ex. signal, red alarm on ss7 interconnection using cisco access server?
A: Yes. The tapping box has built in high impedance to do just this.

Q: You plan to record other sources than E1/T1/J1 ?
A: No.

Q: digital PBX lines? like for system phones?
A: No.

Q: in ALU-> DR-Link or AES Avaya Server
A: In this case, I believe you want to trigger the recording from the proprietary CTI links available on PBXs. Every vendor provides their own interfaces and APIs. We do not provide direct interfaces to these. You need to develop these yourself.

Q: where can i find the sample code for tapping
A: Please visit our wiki.sangoma.com pages for more information.

Q: Thanks it was well presented
A: You’re welcome. We hope to see you at the next webinar.

Q: What is the reistance in the tapping box
A: The resistor for high impedance is 1 KΩ (Kilo ohms).

Q: Does Sangoma provide the pinouts for the cabling for the T116
A: Yes. This is on our wiki.sangoma.com site.

Q: Can you use 1 x A102 or do you have to use 2 x A101
A: It is not cost effective to use 2 x A101, plus it does not really work with our drivers.

Q: If recording conversations, what would you use to do the recording? Asterisk MixMonitor?
A: This application is for PBX only. You need to write an application that will merge the 2 receive pairs into a single conversation.

Q: Hi, The RX side Card is a 1 E1 card or a Double E1 card?
A:  For each E1 you need to monitor, you will need to terminate on 2 E1 ports. So at minimum, you need an A102.

Q: How & where will get help guide?
A: wiki.sangoma.com

Q: please i need to know why sagoma still using an ID power connector from rear at sangoma A200 and A400 series?? I hope it will be sata power connector as all the server now use sata powers
A: We use molex.

Q: Want to know how effective is solution and how live call can be monitored
A: We provide the means for interconnection, not the final recording platform. How effective a solution is in not based on Sangoma, it is based on the application developer that uses our boards.

Clearcable Webinar: Everything you wanted to know about SBCs but were aftraid to ask – May 7 – 12PM EST (English) – Q&A

Thank you to everyone who joined the Clearcable Networks webinar on May 7, 2013. Below is the Q&A key from the English session @ 12:00PM EST as presented by Simon Horton. Please review the answers and don’t hesitate to let us know if you have further questions or comments.

Clearcable Webinar:
Everything you wanted to know about SBCs but were afraid to ask
Q&A Key

Q: ITSP acronym for?
A: Internet Telephony Service Provider. A company that is setup to terminate SIP trunks.

Q: thanks
A: You’re welcome.

Q: Is there any encryption between SBCs across the Internet?
A: Sangoma SBCs support SIP over TLS to encrypt the call setup signaling and SRTP to encrypt the voice stream. Alternatively, VPN tunneling is also supported directly on the SBC.

Q: thanks
A: You’re welcome.

Q: we can’t see the questons
A: Hi Don, if you missed any of the questions that Simon went through, we’ll create a Q&A key for attendees after.

Q: For a telco with outbound TDM based traffic, can an SBC be used to protect the telco from hacks on customer PBXs attached to the primary switch via, SIP trucnks, PRI and analog lines?
A: An SBC can be used at both ends of a SIP trunk and Sangoma has SBCs in its portfolio scaled for both applications. The SBC at the customer premise will prevent hackers accessing any SIP equipment on the SBC and making fraudulent calls through the carrier. The SBC at the carrier end will prevent unwanted intrusion into the core network.

Q: thank you , so much for your time everyone. its much appreciated
A: You’re welcome, hope to see you next time.

Improving phone system can improve image, save money

With the wrong phone system in place, calls can be missed and customers can be left unsatisfied. VoIP professional Rachel Greenberg wrote on Business 2 Community that having a good customer call center phone system in place helps to present the company as professional, which can ensure that the businesses is not losing customer to the competition. Since many potential customers still make calls to companies to ask questions, schedule appointments and make purchases, using unified communications and VoIP to improve a legacy system can be a great move that will set the business apart from others if done correctly.

Greenberg said companies should choose a system that will fit their business and help them save money. With some contact center technology providers, businesses have to account for extra costs per extensions, but others may provide metered extensions at less cost.

"Metered extensions usually cost less per month, but carry a per-minute fee, usually around a few cents," she said. "However, if you have any employees who only do a small amount of calling, or some extensions that will only be used on rare occasions, metered extensions are a great way to save money. Other providers may also offer virtual extensions, which are IP extensions for mobile phones. This means that an employee can be reached through the central PBX even when out of the office."

Improving a system with VoIP can also help organizations reach a wider national and international audience, as the technology provides unlimited calling within the U.S. and Canada from many providers and much cheaper international calls than with legacy systems. This can help increase the company's reach and give wider access to a demographic that could not have previously been reached.

VoIP can bring more flexibility
Widespread used legacy phone lines are not only more expensive, but they also keep workers tied to their desks with few options for being able to spread out. PC World said VoIP providers can offer mobile apps that will allow phone calls to be forwarded to devices, no matter where an employee is located.

"Scalability is another boon," the website said. "Rather than having to invest in costly new hardware, adding new extensions to a VoIP network is typically as easy as connecting your SIP-enabled phone to the network and tinkering with some software settings – and if you use a phone that's certified for use with your provider or software, it could be as simple as plug and play."

Ban on telecommuting may not be good for business

Unified communications professionals were boggled when Yahoo CEO Marissa Mayer initially announced that the company would no longer allow employees to work remotely. PC World's Christopher Null wrote on PC World that she was interviewed last week at the Wired Business Conference on many  topics, but when it came to the new law saying she felt employees were "ripping her off" by not spending enough hours on the company virtual private network. Null said this has become a big issue in the industry, even as Mayer said her position has been misrepresented since workers can still remotely work on nights or weekends and because Yahoo now fosters a highly collaborative environment.

"But the most important thing Mayer said is that she isn't particularly against telecommuting, just that it is 'not right for us, right now,'" Null wrote. "She has a point. Telecommuting doesn't work for 100 percent of companies 100 percent of the time, but the positioning is a little ironic given Mayer's earlier decisions as CEO. As one of her first orders of business last year, she gave every employee a new smartphone."

According to he Families and Work institute, 63 percent of employees now telecommute. Over the past eight years, this has doubled. Null said this makes Mayer's lack of willingness to allow work from home something that is simply "out of step with reality."

While some Yahoo employees may have spoiled it for the rest of the company's workers, he wrote that these issues are better solved via disciplinary action instead of having the entirety of the workforce be punished over what a few people. In fact, Null wrote failing to offer a way for workers to telecommute will limit the perks available to employees. When he worked from home as a Yahoo!employee, Null said he saved over 2,000 hours of driving time and said this is money that otherwise would have gone to gas and lost productivity.

Top benefits of working from home
With a quality unified communications system such as Microsoft Lync in place, employees and businesses alike can see a lot of unique and powerful benefits from a remote working schedule. Entrepreneur Kevin Kruse wrote on Forbes that teleworking's perceived benefits for companies are that more talent can be hired outside of geographical limits.

According to a 2012 survey conducted by Microsoft, additional Benefits included:

  • 60 percent said it provided a better work/life balance
  • 55 percent liked being able to save gas
  • 47 percent said avoiding traffic was key
  • 45 percent said they would be more productive at home

VoIP Encryption

Because VoIP voice signals often travel along unsecured channels such as the internet, measures must be taken to prevent eavesdropping by unauthorized third parties.

Eavesdropping on traditional phone lines requires direct access to the physical phone cable.  Standard building security and inaccessible phone cables reduces the threat substantially, and increases the risk to the eavesdropping criminal.

VoIP voice trunks on the other hand, can be much more easily intercepted and with less risk to the criminal, because they make numerous hops across the publically accessible internet.

Secure Real-time Transport Protocol (SRTP) is a standard method for encrypting VoIP calls.  SRTP uses a highly secure encryption algorithm with a relatively small CPU load.  Signaling is protected with Secure Real Time Control Protocol (SRTCP).

There are several ways of implementing encryption.  Voice can be encrypted/decrypted by Session Border Controller (SBC) software, or by dedicated transcoding hardware.  There are pros and cons to each choice.

The pros to using a pure software approach is that the same equipment already used for the SBC can handle encryption.  This is very cost-effective for low call volumes, i.e. fewer than 25 simultaneous calls.  When using Sangoma software, no additional licensing is required to implement this option. The con however, is that this approach is not very scalable.  As the volume of calls increases, the CPU load required to handle encryption will limit the total number of simultaneous calls that the SBC can handle.  Adding additional SBCs to handle encryption and other transcoding tasks is not cost-effective.

The alternative is to use dedicated encryption/transcoding hardware to manage this task.  The pros are increased scalability and more cost-effective processing of higher call volumes.  There are no cons for higher call volumes (i.e. greater than 25 simultaneous calls).

Depending on the application, this may be a board in the server, a small enclosure, or a rack-mounted appliance.  Each solution connects to the network via Ethernet.  For moderate to high call volumes, this is the superior method.  Transcoding hardware can be added as needed, making this approach extremely scalable.

Sangoma offers a flexible approach to encryption and transcoding.  Small installations handling 25 simultaneous calls or fewer can be accommodated entirely by software.  Sangoma’s hardware-based SBCs include hardware-based encryption and transcoding; the enterprise models can process up to 400 calls, and the carrier models can process up to 4,000 calls.  If additional encryption is required for an increased volume of calls, the D-150 transcoding box is ideal for up to 400 simultaneous calls, and the NetBorder Transcoding Gateway scales from 400 to 4,000 simultaneous calls.

Unified communications can help improve school safety

Businesses that adopt a unified communications solution such as Microsoft Lync expect to get great collaboration and messaging tools. In the wake of recent school safety issues, Patrick Jones, director of technology at Valley Park School District in Missouri, wrote on Business Solutions that these programs can be used to help keep schools more secure as well. Schools everywhere are re-evaluating policies and security procedures to help prepare for a catastrophic event.

“One of the greatest needs discovered in these assessments is communication and coordination during the response to event phase of a situation,” he wrote. “Statistics have shown that, in an active shooter scenario, an average shooting event lasts 13 minutes, and the average first responder arrives on scene in 10 minutes. Any opportunities to increase communications that alert of the issue quickly, allow first response to the appropriate location on the scene, reduces the shooter’s event, and mitigate issues is essential to the safety of students and staff.”

In his school district, there are approximately 1,000 students between kindergarten and 12th grade. They recently held discussions about what to do in the event of a calamity and found that unified communications was the way to go, as it offered instant messaging, showed a presence display as to where employees were and if they were available, featured faxing to desktop and more features that could prove beneficial in a worst-case scenario.

UC, schools and first responders
Another important feature is an event notification system that alerts emergency personnel if something bad happens. A paging system built into their solution also allows the district to better respond to events.

“In the event of an issue across campus, distributed access is available to make the initial report over the paging system by anyone, broadcasting through the speakers on the phone and alerting the entire school or district,’ he wrote. “Effective communication resources are essential in any safety and security issue, especially those that involve children.  So it is imperative to deploy those resources best suited to the situation, where the form of the solution meets the function of the needs.”

Movement to the cloud
Schools can make their UC implementation even more effective by hosting their system in the cloud. A recent survey by CDW found that 16 percent of all organizations said they were fully implemented with unified communications and 4 percent said they have cloud-based unified communications solutions deployed. Although the survey talked with 900 IT professionals across a wide variety of industry sectors, THE Journal noted that a number of those polled work in primary or secondary education.

Sangoma news roundup May 13, 2013​

Adopting new technology no longer just means buying large hardware and constantly making expensive updates to new software. With tools like VoIP and unified communications, companies can now stay up to date with ease. Some news stories in the past month have showed some of the options organizations can have to stay updated and reasons to do so.

Using VoIP with tablets
One of the biggest perks of VoIP is that numbers can be used on many unique devices. With the use of tablets in business exploding, these mobile gadgets can now easily be used to make phone calls from anywhere that has a Wi-Fi, 3G or 4G connection, according to PhonesReview. This gives companies more flexibility and features than ever. "In utilizing the service on an iPad, users have a way of reducing their monthly calling costs while also expanding their capability," the website said. "Fitting a tablet with a VoIP app enables users to utilize VoIP without having to switch their provider over."

Call quality better with VoIP
Although costs and efficiency may be two of the bigger reasons companies adopt VoIP, the quality of calls can be improved with this technology as well, VoIPReview said. Businesses and households can see some great benefits from VoIP, including less expensive calls and easier scaling of how many lines are needed. With a good internet connection in place, phone calls will be clearer than they were with legacy carrier systems. "Businesses that use old analog technology must add more circuits each time they need more room for calls. Analog technology users also need a technician to help them add, remove, or change extension lines whenever they need to make changes to the office's extensions."

Ensuring VoIP security can be easy
Security should always be a thought when dealing with technology that sends data between users, and  VoIP is no exception. However, most data may be much harder to secure than VoIP is. TechDay gave some tips for securing the technology, including applying a daily toll limit to the service so scammers aren't allowed to charge for overages, utilizing a transport security layer with the SIP trunking solution, use using outside security options to protect the surrounding network and always having the most secure data separated from this network in case of worse-case scenario situation with a data leak. "If a fraudster gains access to your PBX, they can initiate multiple calls to high-priced toll numbers of which they share the revenue," the news source said. "This is typically done at night with the calls being directed to numbers in island nations where the cost of telecommunications is high, meaning higher returns for fraudsters." While TechTarget said there is no perfect way to secure a VoIP program, each company must do diligence to be sure they are getting the most protection possible.

SIP trunking becoming popular option
SIP trunking has become a go-to technology for companies to connect IP PBX and unified communications, according to Diane Myers, principal analyst for VoIP, UC and IMS at Infonetics Research. She said this is the fastest growing areas for companies turning to VoIP, as adoption has increased to 83 percent in 2012. There is still only a 15 percent penetration rate in North America, meaning there is a lot of room for growth in the future. "New geographic regions are opening up, and SIP trunking and hosted UC continue to heat things up, fueling growth," Myers said. Along with the growth of SIP trunking has come a unified communications service revenue growth of 17 percent and VoIP 9 percent in 2012.

Have a company-wide approach to VoIP security

If the entire company and all employees are held accountable for security, then all systems are more likely to remain secure. Telecommunications expert Jon Arnold wrote on VoIP-News that businesses must start thinking about securing VoIP as early as possible to make sure threats do not harm a business.

"Regardless of your IT resources or expertise, the key is to think holistically about how VoIP fits into your overall data network," he wrote. "Otherwise, the path of least resistance will lead to a patchwork approach where you keep adding application-specific security solutions. Over time this becomes expensive, cumbersome and not very effective. A better approach is to develop a comprehensive plan – with an architectural framework – that maps out where and how VoIP poses potential risks."

How to have the best VoIP security possible
Arnold said there are some key steps that businesses must take when it comes to security, with the first being to divvy out responsibility for who is securing the program. While the security plan needs to be centralized, workers should know what their role is for making sure the company's VoIP program is kept safe. Once this plan is in place, organizations need to constantly check their network-wide security, as the threat of malware and intruders trying to steal the data being used on the VoIP network is always present.

To have the best success in with any security problem, company decision makers should develop clearly written policies that the entire organization can understand. VoIP is likely a new technology to most within the business, so establishing what is expected from end users will be key to keeping everything in check. Solidifying this can be done by prioritizing education and training, Arnold wrote.

"Not only are all of these [VoIP] options fairly new, but they are driven by end users as they see fit," he said. "Many are outside the conventional scope of the LAN, making them highly vulnerable to security threats. For all these reasons, employees must be made aware of the potential risks, and more importantly, how they can take the right precautions. In short, they need to be considered part of the solution, otherwise they will end up being a big part of the problem."

Resource Nation said companies can make their VoIP calls over virtual private networks to get even better security if they would like to, otherwise there are third-party security apps that should be utilized, digital certificates that must be verified and authentication of the calls and data transfers is, as always, a must.

Video, mobile and cloud represent the future of UC

Mike Seagall, director of IT infrastructure at Flotek, recently told eWeek that the company grew from a smaller oil field logistics and products vendor to a large, international company with more than 400 workers because of unified communications. The company combined VoIP with features like instant messaging, and audio conferencing, which allowed users to communicate and collaborate anywhere with any device. As a result, the business has reduced capital and operating expenses and decreased support time and costs, which has yielded a better return on investment and simpler management. He called it "amazing" that one person can easily manage all these endpoints from one screen.

Giovanni Mezgec, general manager of Microsoft's Lync UC platform, agreed, saying that there are a lot more ways people communicate and it is best to make collaboration as simplistic as possible. With video conferencing, cloud computing collaboration and mobile devices representing the future of the industry, it is clear that there will likely be a much larger drive toward unified communications in the coming months and years.

Rich Costello, senior research analyst of UC in IDC's Enterprise Communications Infrastructure unit, told eWeek that the idea of  unified communications has been around awhile, but the market is set to grow significantly in the next few years. The industry was previously worth $26.2 billion and will likely grow to $38 billion by 2016. Cloud, video and mobile trends means unified communications will likely get even better in the next few years too.

"It's been tough for the ROI piece, but companies are starting to get it, especially with mobility and what they can do there," Costello said.

The changing workplace has forced companies to adapt, with mobility, video and social forcing organizations to drive forward their technology initiative. Carl Wiese, senior vice president of collaboration sales at Cisco, said people on the road are telecommunicating however they would like and said the way of the work world is much different than it was even a few years ago. VoIP expert Pejman Roshan told eWeek that the majority of companies that are adopting cloud computing-based unified communications are already using the cloud in some fashion, but eventually more will start to embrace this technology because of its clear benefits.

Considerations for video
Before adopting any solution, companies must be sure they are being smart and getting everything they need from the unified communications platform. Especially when it comes to video, TechTarget said questions must be asked about integration and how video has worked for other businesses.

"Lastly, take a close look at functionality," the website said. "Video conferencing has been around for a long time and has developed a complex set of functionality, including data sharing, far end camera control, best path routing, firewall traversal solutions, etc. Many of these features depend on extensions to the signaling protocols that may not be available in the UC environment."

TechTarget said companies looking to bring in a unified communications system with all of these functions may want to get help from the vendor to ensure the integration goes as well as possible.

VA improves contact center

The large backlog being carried by the U.S. Department of Veterans Affairs surely netted the department a lot of phone calls at its contact center, but GCN senior editor Rutrell Yasin said that until recently, getting the right claims information from VA was somewhat difficult.

"Call agents had to individually query 13 different systems to find claims information," he wrote. "The systems often would time out as agents searched multiple databases for information, leaving callers to either receive a busy signal or hang up while on hold. And because the process was not standardized, each call center agent had to apply different techniques with different systems to find answers to veterans' inquiries."

To illustrate this, Yasin wrote that it wasn't but three years ago that callers for veterans benefits only had a 49 percent chance of reaching the correct agent and getting the information they were looking for when phoning the contact center. However, VA has over the past year looked to transform how this system works and make it easier for callers. There used to be 13 different systems, but the department now has a unified view of all systems from a single screen, giving them the ultimate control over their system and allowing the contact center to operate more efficiently.

The many business benefits of an improved call center
Businesses don't have to be the size of VA to have a better contact center in place, according to Call Center Helper, there are some areas to look at to help improve the system. To garner the best possible results from the center, organizations should document the process currently in place, be sure to keep the best staff with the company and always quantifiably measure contact center performance.

"The drive for efficiency is often seen to be at the expense of the customer," the website said.  "The examples given here are aimed at both providing a cost saving, but also at improving the level of service a customer receives. If we can remove the need for the customer to call in the first place we have made significant progress. When customers do have to call, speaking to a knowledgeable employee, who has been with the company for some time and has the ability to deal with multiple queries on one call, will offer the customer a one-stop shop approach to their query."
