What Is UCaaS Voice Resiliency and Why Is It Important?

What Is UCaaS Voice Resiliency and Why Is It Important?

UCaaS voice resiliency refers to the ability of a UCaaS voice service like Microsoft Teams Phone to withstand and recover from various disruptions, such as power outages, network failures or service unavailability.

But even though Microsoft recently announced an impressive 99.999% uptime guarantee for Microsoft Teams Phone,1 businesses can still lose their connection to Teams due to unforeseen events like local power cuts or damage to communication cables.

The Absolute Importance of Branch Resiliency

Smart businesses in today’s hybrid work era understand exactly why they need to build a resilient UCaaS platform that can provide consistent and reliable voice communications services to users, regardless of the location, device or time zone. To them, UCaaS voice resiliency is vital for several reasons:

  • It enhances business continuity by ensuring that critical communications functions remain operational, even during downtime. This helps businesses avoid operational and financial losses, as well as reputational damage.
  • It improves user experience by providing seamless and high-quality voice communications services to both employees and customers. This fosters greater satisfaction and loyalty, as well as productivity and collaboration.
  • It supports digital transformation by enabling businesses to adapt to changing needs and demands, such as remote and hybrid work models, global expansion and customer expectations.

AudioCodes Solutions for Microsoft Teams Phone Resiliency

AudioCodes offers a range of solutions that can enhance the resiliency and high availability of Microsoft Teams Phone, both on-premises and in the cloud. These solutions are based on robust, enterprise-grade hardware and software components that are certified for Microsoft Teams, including:

Session Border Controllers (SBCs)

AudioCodes’ award-winning Mediant SBCs are designed to ensure secure and uninterrupted voice connectivity. They play a pivotal role in facilitating seamless failover and load balancing, enhancing the resilience of the communications system.

Survivable Branch Appliances (SBAs)

For organizations with multiple branches or remote sites, AudioCodes’ Direct Routing SBAs provide an essential layer of redundancy. These appliances ensure that, in the event of a disconnect with the central service, local branches can operate independently and maintain voice service continuity.

Edge Proxy Appliances

For organizations that use compatible SIP devices to make and receive calls via Microsoft Teams using the Teams SIP Gateway, Edge Proxy appliances provide a device that acts as a proxy between Teams SIP Gateway and SIP devices in the branch, supporting local breakout to the PSTN. They optimize the media path for voice calls by enabling local media breakout and bypassing the Microsoft Teams media relay. They also deliver resiliency for registered SIP devices when the site loses connectivity with Teams services.

5G Backup for Centralized SBC SIP Trunks

For distributed enterprises that use a centralized Microsoft Teams Direct Routing SBC for PSTN breakout, 5G backup can provide an alternative connection in case of a WAN outage or loss of connectivity with the Teams service. This enables uninterrupted calling via the branch SBA and the core SBC.
