Abstract
Various embodiments provide methods and systems operable to receive a VoIP signaling packet, the VoIP signaling packet including information indicative of a request for trace information, to append trace information to the VoIP signaling packet; and to route the VoIP signaling packet with the trace information to a next network element on a path to a destination node. If an error condition is encountered, the VoIP signaling packet with the trace information is routed to a previous network element on a path to a source node.
