Hello everyone,
Im struggling to configure SIP trunk between Shoretel Mobility Router and my CME running on ISR3945E. They are in a same room, directly connected. Voice tasks of this kind are something I dont cope easily with, as I come from switching/routing domain, and do voice on pretty much trivial basis.
Anyway, SIP as a protocol is already running on my CME, since I have few SIP extensions live using X-lite software. Could someone kindly guide me through the process of making this SIP trunk work, pointing to local IP address of Shoretel router?
Googe presented me with this piece of config, and I wonder if that`s all to it:
dial-peer voice 1234 voip
description ** SIP trunk **
destination-pattern 8...
monitor probe icmp-ping
session protocol sipv2
session target ipv4:xxx.xxx.xxx.xxx
dtmf-relay rtp-nte sip-notify
codec g711ulaw
no vad
Do some ports need to be specified also? Something else I missed?
Thank you,
Milos

Hi Milos,
Do you have the following configured
voice service voip
allow-connections sip to sip
SIP Trunks on CME are typically configured under sip-ua configuration mode. Here's an interesting document

This whole SIP thing turned out to be much easier than I expected, having SIP as a protocol already up and running on my CME. It was just a matter of adding a dial-peer voice rule and specifying the IP address of other device.
There is probably some optimization I could have done, but Im not fixing if it`s not broken, for now at least
