Hello Charles,
Thanks for your reply. Could you please elaborate on your idea? My call flow is:
sipp SUT
INVITE ---------->
100 <----------
180 <----------
200 <----------
ACK ---------->
[ NOP ] <<-- pcap play audio (30 mins)
[ NOP ] <<-- pcap play video (30 mins)
Pause [ 4000ms]
[ NOP ] <<-- pcap play DTMF, triggers the first
re-INVITE on the SUT
INVITE <----------
200 ---------->
ACK <----------
Pause [ 30:00] <<-- here all the INVITEs arrive
BYE ---------->
200 <----------
The problem is, during the second Pause (30 min) there is a re-INVITE every
2min30. I could just wait for an INVITE 12 times and deal with each of them,
but 2min30 is only the default case, in other words it can be set to anything
at all...
Thanks
Marek

Marek,
I would try inserting an optional receive, and some goto labels.
