Survivable Branch Appliance Functionality
The Survivable Branch Appliance function in the Lync Server included in DMG 4000 Gateways has the following components:
•
SIP Registrar and Proxy for normal and failover routing
•
Mediation Server for communication between Registrar and IP-PSTN Gateway
•
IP-PSTN Gateways for routing calls to the PSTN as an alternate transport in case of WAN outages or anomalies
The Survivable Branch Appliance function can support up to 1000 users. If a branch office’s WAN connection to a central site
becomes unavailable, the Survivable Branch Appliance enables branch users to continue to handle outside and inter-site calls via
the PSTN, make intra-site calls, use voice mail, and connect with audio conferences via the PSTN.
