Claim:
A method for session initiation protocol (SIP) server identification comprising: tallying a plurality of distinct uniform resource indicators (URIs) associated with one or more source IP address in a plurality of SIP request messages to produce one or more first tally count; tallying a plurality of distinct URIs associated with one or more destination IP address in the plurality of SIP request messages to produce one or more second tally count; tallying a plurality of distinct URIs associated with one or more source IP address in a plurality of SIP response messages to produce one or more third tally count; tallying a plurality of distinct URIs associated with one or more destination IP address in the plurality of SIP response messages to produce one or more fourth tally count; and identifying a SIP server candidate corresponding to an IP address upon the corresponding first tally count exceeds a first threshold, the corresponding second tally count exceeds a second threshold, the corresponding third tally count exceeds a third threshold, and the corresponding fourth tally count exceeds a fourth threshold.
