摘要： 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.

摘要： According to an embodiment of the present invention, an apparatus for addressing compatibility in a session protocol environment is provided that includes a communications platform operable to communicate with a first endpoint and a second endpoint and to recognize signaling capabilities of the first and second endpoints. The apparatus also includes a media termination point (MTP) operable to communicate with the endpoints and the communications platform, the media termination point being provisioned by the communications platform in a stream that involves the first and second endpoints if a signaling compatibility issue is present amongst the endpoints. If an out-of-band digit from the first endpoint is received by the communications platform, the out-of-band digit is sent to the MTP, which is operable to inject a digit associated with the second protocol into the communication session such that a mapping occurs between the digits for the first and second protocols.
