ABSTRACT:
Methods and systems are described for performing alternate routing of communications in a network. The system initiates a communication from an origination endpoint in a packet-switched network, such as a VOIP network, to a destination endpoint, and determining, according to selection criteria, whether to route the communication to the destination endpoint using at least a second circuit-switched network, such as the PSTN.
