SYSTEM AND METHOD FOR PROVIDING DEBUG INFORMATION IN SESSIONINITIATION PROTOCOL SESSIONS

摘要

A system and method for providing debug information in messages exchanged between two user agents in a session established in accordance with a sessio n initiation protocol (SIP). In an exemplary embodiment, a SIP request that comprises an additional debug header is generated by a user agent client, fo r transmission to a user agent server. The additional debug header can be used to provide information on errors identified in a SIP response received earlier by the user agent client, for example. This information may be used by a network administrator of the user agent server in the debugging of applications or network maintenance.
