[Asterisk-Users] Cisco DTMF Issue

[Josh J. Zuerner]

We're having an issue with connecting a Cisco ITS installation to * such that DTMF tones are passed to *.  DTMF tones aren't passed to voicemail or to any of the interfaces behind *.   On the Cisco Side:   dial-peer voice 8 voip  destination-pattern 9999$  session protocol sipv2  session target ipv4:172.16.1.249  session transport udp  dtmf-relay rtp-nte  codec g711ulaw  no vad   We have also tried using rtp payload-type nte to adjust the nte port value to 101 versus 100.  SIP Notify doesn't work, cisco-rtp doesn't work.  I have tried every possible dtmfmode= option [inband, rfc2833, or info] within this SIP device.  Toggling session transport udp, no vad, and the codecs seem to be no use.  I'm frustrated and puzzled.  If anyone can provide some guidance, I'd be very grateful!  We're trying to get this up and running this morning.   Josh
