My company has a sip trunk to our voip provider and everything works great. They don't use credentials to authenticate, just based on our ip address. Recently we started working with an IVR vendor to setup a sip trunk between our UC560 and an on premise Asterisk server (I don't have control of the Asterisk server). Here's what I've entered on on the UC560:
dial-peer voice 2222 voip
description IVR System
session protocol sipv2
session target ipv4:10.27.75.25:5060
session transport udp
incoming called-number 351
voice-class sip dtmf-relay force rtp-nte
ip qos dscp cs5 media
ip qos dscp cs4 signaling
When I place a call to 351 I receive a busy signal immediately and the IVR vendor says they don't see any traffic hitting their server. I've included a couple of debugs captured during the failed call. If someone could have a look and point me in the right direction that would be awesome. I probably left some important info out so please let me know if I can capture anything else.
According to the voice_debug the UC recieves a "403 From: URI not recognized". It appears the device responding does not like the URI that the UC sends. The far end device is not allowing the connection from the UC. Hope this helps.
Thanks for responding and checking the debug. Obviously I have to work with the vendor of the IVR system and I'll share this information with them. In the debug are you able to see what far end device is responding? I just want to make sure the traffic is destined for the right place and not trying to use my PSTN sip trunk. Thanks again for your help!
