Re: [Sipp-users] Problem with recv

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Alice's message will have a different Call-ID than Bob's existing call. 
Therefore the message will not be identified as part of the conversation.

You can use three or fou r SIPp instances for this to work.
1. Bob's Registration
2. Bob's Message Receive
3. Alice (or Alice's Registration and Send)
