 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.
