Quintum’s Tenor-S Survivable VoIP Switches provide local IP endpoint registration and call routing functionality in the event that communication with the central proxy is lost. In these circumstances the Tenor-S takes over as the local routing engine, supporting the local IP phones, and in addition providing gatewaying capabilities to enable IP phones to place calls out over the back-up PSTN connections. The Tenor-S continues to monitor the status of the central SIP proxy and, once communication is reestablished, passes routing responsibility back to the central proxy. Handles: FXS FXO VoIP SIP SVS |
