hey everyone,

looks like I found a related problem:


I send this SDP info in my INVITE:
m=image 6000 udptl t38


I receive this SDP info in the 200 OK:
m=image 50682 udptl t38

after that I execute:
<nop>
<action>
<exec play_pcap_video= "t38.pcap"/>
</action>
</nop>


according to wireshark, sipp will send the RTP to port 5068, so it misses 1 
digit in the media port, how can that
happen?

"User Datagram Protocol, Src Port: 6000, Dst Port: 5068"


cheers,

Patrick.
