Method for rerouting communication in a unified communications network

A method for rerouting communication in a unified communications network, the method comprising:

• receiving an inbound call at a first session border controller;
• determining, at a redirect server, a redirect number mapped to an inbound call number associated with the inbound call;
• routing the inbound call to a first call destination based on the redirect number, wherein routing the inbound call to the first call destination comprises:
• opening a first call connection leg from the first session border controller to a proxy server for the inbound call;
• opening a second call connection leg from the proxy server to a second session border controller for the inbound call;
• and
• opening a third call connection leg from the second session border controller to a call destination server for an outbound call based on the redirect number to terminate the inbound call at the first call destination;
• receiving, at a transfer server, a transfer request from a server associated with the first call destination during the inbound call;
• determining, at the transfer server, a new destination number for transferring the inbound call;
• transmitting, from the transfer server, an out-of-band transfer request to one or more servers maintaining the inbound call;
• dropping one or more connections associated with the inbound call to the first call destination based on the out-of-band transfer request;
• and
• rerouting, at the first session border controller, the inbound call to a second call destination based on the new destination number identified in the out-of-band transfer request.
