Why hybrid?
Pure cloud phone systems rely entirely on internet connectivity, when the connection drops, so do your calls. Traditional on-premises systems offer reliability, but often at the expense of flexibility, mobility, and centralized management.
Many businesses don’t fit neatly into either model.

Centralized control without sacrificing flexibility
Manage users, features, and locations from the cloud while enabling workforce mobility across sites and devices. Easily scale as your business grows, without re-architecting your phone system.
Local survivability that keeps calls flowing
Maintain on-site call processing so phones continue to work even if the internet goes down. Hybrid
supports legacy analog phones and devices so you can modernize at your own pace.
Built-in redundancy for business continuity
Automatically route calls over internet, LTE, or POTS to ensure uninterrupted communications during outages, so your business always stays reachable.
Optimized performance, tailored to your environment
Deliver consistent call quality with local Quality of Service (QoS) controls and customized phone features.

Customers spotlight
“One of the biggest selling features was the ability to make internal phone calls should we lose Internet connectivity. Having the StarBox on campus was a safety measure to ensure extension-to-extension communication in the event of an emergency. The system works together very well, users adapted to it quickly, and it really just runs in the background without a lot of fuss.”

Frequently asked questions
What are the key advantages of a hybrid UCaaS solution over a fully cloud solution?
The biggest advantage of Hybrid UCaaS is local survivability. If your internet connection or cloud services go down, your business can still operate using the local, on-premises system. You don’t lose communication because the on-site system keeps everything running smoothly.
Can hybrid UCaaS be customized for specific business needs?
Yes, Sangoma’s hybrid UCaaS solution (powered by Business Voice Plus) can be customized to meet specific business needs. We offer features like custom CRM integrations and Microsoft Teams integration, allowing businesses to tailor the system to their unique requirements.
Is hybrid UCaaS cost effective compared to a cloud or on-premises solutions?
Yes, hybrid UCaaS can be more cost-effective than both fully cloud-based and on-premises solutions. It reduces the need for expensive on-site hardware and maintenance, while still allowing you to leverage cloud scalability and flexibility. This hybrid approach means you can avoid the high upfront costs of an entirely on-premises system and the ongoing costs of fully relying on cloud infrastructure, while still benefiting from both.
How does hybrid UCaaS guarantee uninterrupted business communications?
Hybrid UCaaS guarantees uninterrupted communications by combining the local reliability of on-premises systems with the redundancy and scalability of the cloud. With 99.999% uptime and multiple failover options, if one system fails, the other seamlessly takes over, ensuring continuous operations and minimal disruption to your business-critical communications.
