Stand-Alone Survivability (SAS) Application
The AudioCodes Standalone Survivability Application for the Mediant 1000 (SW/M1KB/SAS) dismisses the possibility of connection loss for remote locations of enterprises that use a centralized IP-PBX server, and for service providers that have a centralized IP-Centrex. Remote offices face the challenge of loss of voice services, including internal calls and PSTN breakout. With this Standalone Survivabilty Application (SAS) you can rest assure business will continue without interruptions.
Stand-Alone Survivability (SAS) Application Overview
The Standalone Survivability Application is an essential feature for enterprises and service providers that deploy a distrubuted IP-PBX solution as it is based on the SIP Back to Back User Agent Functionality (B2BUA). This enables the service back up for SIP clients in case of a network failure. The Media Gatewaty must be installed as a CPE in the customer premises or branch office in order for SIP IP Phones and SIP Soft Phones to be backed up.
Once the SAS feature has been configured on the Media Gateway, the SIP clients register with their central SIP Proxy (the IP Centrex server or the enterprise central IP-PBX) via the Media Gateway that acts as a proxy for all SIP registrations. In the case of connectivity loss with the centralized IP Centrex application or IP-PBX platform, the Media Gateway takes control, enabling new phone registrations and internal calls in the disconnected site. PSTN connectivity will also be backed up if there is a local PSTN connection in the gateway. During network downtime, basic call control features are provided by the Media Gateway, and full functionality is restored once the network has recovered.
