I'm having a strange issue-- I'm running sipp 3.1 (w/pcap support) on Win2k3.  
My UAC scenario is identical to the UAC w/media, except that I'm passing a DTMF 
1 pausing 10 seconds then passing another DTMF 1 and the hanging up.
 
Here's the strange thing-- it seems if I play a pcap file (ie. 
dtmf_2833_1.pcap) for the FIRST time in the scenario, it works fine, but if I 
try to play the SAME FILE again, the DTMF tone isn't recognized.  If I play a 
DIFFERENT pcap file, it works-- it's almost as if I can only play a pcap file 
ONCE.  I traced through Wireshark and it does appear that the same file is 
getting sent as designed (I see the UDP/RTP packets go through)... any ideas?
 
I even tried recording my own pcap file of a DTMF 1-- using this file and the 
stock dtmf_2833_1.pcap works great; however, if I try to play either of these 
files later in the scenario, the DTMF tone is no longer recognized...  I 
apprecicate any feedback!
