I'm communicating with MS Speech Server 2k7 - my SIPp calls are successfully
connecting and I can replay the RTP traffic so I know things from a connection
stand point are very good.
The issue I'm running into is that it seems I can't send two of the same DTMF
digits for the same call - it's like the digit will no longer be recognized
after it was used once. For example, when I connect with the IVR, I send a
DTMF 1 (though pcap play) which gets successfuly processed by the IVR. If I
try to send another DTMF 1 for the subsequent menu, the IVR will not respond to
it. If I send a DTMF 2 (after the first DTMF 1), it is recognized and takes me
to another menu. Anyone run into these problems? I've verified in Wireshark
the DTMF digits are indeed being sent. It's almost as if EACH DTMF digit sent
needs to be unique somehow.
What's even stranger is if I record my call via xlite and SAVE each DTMF digit
sent through the softphone and use it in my SIPp script (instead of the DTMF
digits that come in the pcap directory), everything works fine.... the only
problem is that this is seriously labor intensive and not sure why I have to do
that.
However, if I send the same DTMF digit that I re-created from the softphone,
the same issue occurs (ie. it's not like I can just re-record the DTMF tones
generated via the softphone).
Thanks in advance!
