Avaya/Quintum Remote Office Survivability AppNote

These Application Notes describe the procedure for configuring the Quintum Tenor AS VoIP MultiPath Switch as a back-to-back user agent (B2BUA) in support of SIP endpoints and local survivability with Avaya Communication Manager and Avaya SIP Enablement Services. With the B2BUA functionality disabled, the Quintum Tenor AS VoIP MultiPath Switch serves as a gateway between analog telephones at a branch location and a VoIP infrastructure at a main location using the Session Initiation Protocol (SIP). The Tenor supports failover to a PSTN connection for external calls if the data WAN connection fails. When the B2BUA functionality is enabled, the Tenor will also support SIP telephones at the branch location by performing as an Outbound Proxy. The B2BUA functionality also allows both analog and SIP phones to continue to make internal calls if the data WAN connection fails. This is referred to as local survivability. Emphasis of the testing was placed on SIP interoperability with the B2BUA enabled. Information in these Application Notes has been obtained through DeveloperConnection compliance testing and additional technical discussions. Testing was conducted via the DeveloperConnection Program at the Avaya Solution and Interoperability Test Lab.
