CCM4.2 Intergration with Nortel Meridian Option 11


Please I need assistance with this setup.

We have a 2811 that we are trying to configure as an MGCP gateway to interface a Cisco CCM into our Nortel Meridian PBX

Currently the E1 interface remains down, and in an alarm state

I will appreciate if ther is any documentation to use for this particular Nortel PBX for integration with CCM 4.2 using MGCP gateway..

Re: CCM4.2 Intergration with Nortel Meridian Option 11

Hi Deji,

We tested using the following protocols, ESS5,NI2 and D100 (DMS-100).

The only one that has ever worked properly for us was DMS-100! .

Here are some great docs (have a close look at the White Paper);

Cisco Unified CallManager

Case Study: Nortel 61C PBX to Cisco IP Telephony Migration

From this good doc;

Nortel Meridian PBX and Cisco CallManager Integration

Hope this helps!

Re: CCM4.2 Intergration with Nortel Meridian Option 11

How about any docs in how to integrate a 2821 with a nortel 11c. In this case the 2821 will emulate network for the nortel.meaning that when nortel phones dial out to the pstn..they will go out to the pstn via a pri in the same 2821...also when an inbound call from the pstn needs to be routed to a nortel user, the did will come from the same pri at the 2821. Any configs will be greatly appreciated.

You mentioned E1 so i assume you are in europe, i have this setup with CCME working. The router config may help i at least know the basics here are correct.Ill also attach the pinouts for a cable to a dual PRI card.

BTW the T203 timer was crucial to getting the circuit up and running.
