The problem is each pcap file has it's own series of sequence numbers. So, if you send DTMF-1 (sequence 1->10) followed by DTMF-2 (sequence 1->10), most servers will chuck away the duplicate sequence numbers. There is a patch you can apply to fix that - http://permalink.gmane.org/gmane.comp.telephony.sipp.user/5751 Alternatively, and this is what I did, send the DTMF digits using a SIP INFO message in your XML scenario file.
