Hey Everyone,
I have a functioning integration between CUCM 8.6 and a Nortel CS2100 over a SIP trunk.
Basic flow is like this:
CS2100 --- SIP TRUNK --- CUBE --- CUCM 8.6 + Unity Connection
We had to configure various outbound dial-peers so that when dialing anything on the Nortel side from a Cisco phone DTMF was processed and this works great. Here is an example:
dial-peer voice 12345 voip
description calls to XXXXX
destination-pattern 12345
session protocol sipv2
session target ipv4:1.1.1.1
incoming called-number 12345
dtmf-relay rtp-nte
codec g711ulaw
no vad
So basically dialing 12345 from a Cisco phone routes it to the session target which is an Auto-Attendant on the Nortel from there I can enter DTMF without issue.
Now I have a scenario were I am integrating Nortel phones into Unity and the first step is get the same call flow going the other way so my question is can I do an inbound dial-peer through the CUBE for DTMF normalization and make the session target Unity?

On a CUBE/IOS gateway, each call uses two dial-peers, one for the incoming call leg and one for the outgoing call leg. You can figure out which dial-peer is used for the incoming call leg using the 'debug voip ccapi inout' debug. If you don't already have one matching then create a new incoming dial-peer. Here's a sample incoming dial-peer:
dial-peer voice 1 voip
description Incoming Dial Peer from SIP Server
session protocol sipv2
incoming called-number .
voice-class codec 1 OR codec g729r8 OR codec g711ulaw
dtmf-relay rtp-nte
If the called number are coming in with a specific prefix like an 8 then change the incoming called number to 8.

Then you will need an outgoing dial-peer pointing to Unity

Hi,
That makes sense so this is the inbound DP i created , does it look right?
dial-peer voice 12345 voip
description Inbound test
session protocol sipv2
incoming called-number 12345
dtmf-relay rtp-nte
codec g711ulaw
no vad

Don't forget your session target.

Yes this looks perfect. You don't need a session target for the incoming dial-peer.
