It is unlikely that a real client would re-use the CallID given to it by SIPp
in the Register and Subscribe messages. (Indeed purists would argue that it
would be a breach of protocol to do so.)
What you need to do is to start a new SIPp Server process to receive the
Invite. If timing permits you could terminate the SIPp process that sent the
Register and Subscribe and start a new one. If it does not or you need to
re-Register etc., then you need to have two ports available, one for the Server
SIPp and one for the Client SIPp.
