Abstract
A method to be executed in a session initiation protocol (SIP) environment is provided that includes detecting, by a first agent, a potential lost connection associated with a signaling path. The signaling path couples a first endpoint and a second endpoint and is operable to exchange signaling data. The potential lost connection is associated with a call between the first and the second endpoint, the first agent being associated with the first endpoint. The method also includes communicating a reinvite to a second agent that is associated with the second endpoint in order to determine whether the call between the first endpoint and the second endpoint is active.
