Shameless plug: you may find SippyCup will help make creating load test profiles easier: https://mojolingo.github.com/sippy_cup <https://mojolingo.github.com/sippy_cup>

I don’t know about making the ports random, but you can allocate a unique port-per-connect by passing the “-t un” flag to sipp. Did you really need them random, or just unique? And out of curiosity, why?  Most of the time, the default of “-t u1”, which is a single UDP port shared for all dialogs, works fine.

This gets tricky because SIPp isn’t a real UA.  However, you can write a SIPp scenario that sends a REGISTER then waits for an INVITE.  The Sippy Cup documentation has an example of this.

> (c) Can I play an audio file (or an mp3) after the call starts from both the caller and callee?

You can replay audio in the form of a pcap file. If I need real audio, the easiest path is usually to place a real call with tcpdump running.
