Hi

well, pcap feature does not stand for a true RTP stack.
Packets are replayed without doing any change to RTP header.
Here comes the trouble:
rfc2833 packet must be sent in a rtp flow. If for example you try to
send two 0, the same packets ** with the same timestamp ** will be
sent, and they should be discarded by a standard RTP stack.

One way of solving that would be to concatenate pcap files and fix RTP
headers at script load time.

 

I just record another chip of dtmf with the same digit inside. and play them back sequentially. May this helps you.
