Technically, transction-wise Client sends method requests, like INVITE and ACK and Server is the party that sends the response messages, like 200 or 486. Most SIP applications are both clients and servers, like user-agents and proxies. Here is a good introduction to SIP http://www.iptel.org/sip/intro and if you still wonder why you don't get the indications you want, please read RFC 3261, especially sections 4, 5 and 17: http://tools.ietf.org/html/rfc3261 -- Pekka.Pessi mail at nokia.com ------------------------------------------------------------------------------ Forrester Wave Report - Recovery time is now measured in hours and minutes not days.
