A system and technique for analyzing incoming packets. The path taken by
incoming packets can be analyzed from a near end without having access to
the far end. This can be done even though packets sent to the far end
from the near end, take a different path than that used by the incoming
packets. The process is started by an RTP no op packet sent from the near
end to the far end. The no op packet request the far end to initiate a
trace using a series of media packets that have sequential values in the
TTL field. The results of the trace are either send from the far end to
the near end and a report is complied at the near end, or the results of
the trace are compiled into a report at the far end and the report is
sent to the near end.
