>>  We're having an issue with connecting a Cisco ITS installation to * such

>>  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.
