An initial request is received to establish a communication session. The initial request contains a communication address of a first communication device. A communication server detects that the communication session cannot be established across a primary network. In response, the initial request is repurposed by changing the first communication address to a second communication address. The changed request is sent to a communication system, which adds a field to the changed request that indicates that the changed request is to be sent via a secondary network. The changed request is sent with the field to the communication server. The changed request with the second communication address is sent to a gateway to establish the communication session across a secondary network. A portion of the communication session is established using the second communication address. The first communication address is sent in the portion of the communication session using Dual-Tone-Multi-Frequency (DTMF).

Communication failover in a distributed network

Methods and systems for supporting the alternate routing of calls between endpoints, such as session initiation protocol (SIP) endpoints, are provided. An inner gateway alternate route (IGAR) application is invoked when the primary, Internet protocol, communication network is overloaded or otherwise unable to handle a call. The IGAR application assigns incoming and outgoing trunks, and serves as a contact point for session managers in routing the trunk call.

Alternate routing of voice calls in a heavily loaded SIP network

In one embodiment, an enterprise network is provided that includes a mobility agentassociated with a switch/serveror. The mobility agent creates a visitor application recordassociated with a second communication device. The visitor application record is associated with a first subscriber. A second subscriber is normally associated with the second communication device, and the first subscriber with a first communication device. In response to creating the visitor application record, the native communication device record is associated with a virtual communication device having the same public and/or private numbers as the second communication device
