Microsoft Teams direct-routing-as-service with enterprise-grade resilience

The Call2Teams platform is architected for reliability and scalability.

Operating in Microsoft’s Azure cloud and served from super-clusters in four continents. To ensure consistent and high levels of availability, the service uses in-cluster HA (multi-load balancers per) with multi-geo/intercontinental failover.

Utilizing the latest platform and elasticity components available in Microsoft Azure. Features such as platform-as-code and automatic scaling of the database, App Service, and SBC media nodes ensures the platform architecture will meet its multi-million-user design specification.

Delivering continuity of service – a recent example

Microsoft recently had an outage of their phone platform across Europe and North America – with users unable to make calls for several hours.

During this outage, our Call2Teams customers had a far smoother experience.

Call2Teams operates a global fabric of call-management and Direct Routing SBCs deployed across 4 continents and 6 Azure regions, which enables sophisticated and rapid management of call routing. The Call2Teams system automatically rerouted calls to other geographies resulting in only a short downtime.

There is a normal failover method that catches most transitory issues on the Microsoft network, but this failure was unusually severe and required some quick-thinking by the team to resolve. Call2Teams customers were back on the air within a fraction of the outage time.

Deploying multiple layers of resilience

The mission-critical nature of some organizations inherently requires them to deploy multiple layers of resiliency for their communications services.

An extra layer of resilience can be deployed with on-site SBAs.

The Call2Teams service also provides Interoperability with the Ribbon family of SBAs. Providing an on-site SBA element to our cloud solution, providing a local backup element. During the unlikely event of a network link or Microsoft 365 outage, the SBA enables Call2Teams customers to continue to make and receive phone calls.
