  • System and method for providing a compatibility feature in a session initiation protocol (SIP) environment
    Patent number: 7778274
    Abstract: 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.
