Abstract:
1. A method, comprising: recording context information for a first call session between a first call terminal and a caller; storing the context information with a context identifier; generating transfer error context information having the context identifier, a transfer error context header with a resource identifier of a resource to transfer the first call session to in the event of a transfer failure event, and a set of error codes, wherein an error code defines a transfer failure event that automatically initiates a transfer failure recovery operation; sending the transfer error context information to the first call terminal; attempting to transfer the call session to a second call terminal; receiving a code indicating that the transfer did not occur; comparing the code to the set of error codes in the transfer error context header; and automatically initiating a second call session with the resource identified by the resource identifier when the code matches a code in the set of error codes.
