Guys,
We have an issue where a call comes in to the System and then gets sent back out to an 8xx number. When the callers get the IVR at the 8xx number it is not recognizing DTMF, but it was at the NuPoint.
Working with the SIP Provider and getting packet captures, we don't have an MBG, they are saying that the second call, Forwarded, going out to the 8xx number is not putting any SDP in the message and therefor they are sending it out as an In-Band DTMF call instead of Out-Of-Band.
Does anyone know how to solve this problem as I already have Send SDP in the Initial INVITE set to yes as that was a requirement originally?
Thanks,
TE
