Need to display IP phone name when Nortel phone calls

I am trying to clear up some issue on our VOIP implimentation. We have Nortel phones trying to call IP phones and they do not get the name display of the party they call until it is answered (vmail or user). People want to see the name when the call is dialed. What paramter am I missing to show this? Is it on the D-channel programming in the PBX or the route, or on the gateway config?

Ideas would be helpful..

Re: Need to display IP phone name when Nortel phone calls

The short answer to this is "it depends". What gateway are you using to interface to the Nortel, What version of CM are you using, and what ISDN switch type are you using?

I've sucessfully integrated into Nortels using IOS based gateways and DMS100 emulation. If you have an IOS based 12.2 GW and CM 3.1 or later, I can send you the config. You'll need the Nortel set up to emulate an SL100 trunk.

I am running CM 3.2.2c and using a VG200 (MGCP) gateway running 12.2.11 T3, connected to the Nortel Opt 81. The Route is built as an SL100.

To help narrow down where the issue is try running debug isdn q931 on the VG200 and see if the name is being passed in the initial call set-up message.

If it isn't then the config problem is on the PBX.

If it is, run a debug h225 asn1 and see if the GW is trying to pass the info to CCM.

Even if the PBX is passing the info, it may be being passed in an IE that the GW/CCM don't understand or process.

Re: Need to display IP phone name when Nortel phone calls

When I try and run the debug h225 asn1 or h225 events and place an incoming call to the IP phone from a PBX phone I show no results. Term mon is on. The name does show up on a q931 debug.

debug isdn q931 is ON.
