CCM 4.1(3) integration with Nortel Meridian Option 11

Unanswered Question
Apr 2nd, 2007

Hi

I have CallManager 4.1(3) on one site and a Nortel Meridian system on another.

I am not supporting the Nortel system but I need to integrate the 2. The Nortel

system is as follows

5 cabinet Option 11, succession 3..with basic feature set.

These will be talking through a 3825 isr router.

There is no requirement to pass phonebook directory traffic to display

extension numbers etc.

The pbx guys are telling me I need to have the Nortel feature set upgraded to

an Enhanced feature set is order to pass qsig messages. I found this odd. Can I

not buy a qsig license?

Thanks

Michael

I have this problem too.

You do not have to use QSIG, you can use any isdn switch-type, I would recommand using National NI, which will give you the caller ID and name. You need QSIG if you require some advance features i.e. MWI from CallPilot VM system, etc.

Hi Michael,

Just to add a note to Chris's excellent info. We run a CCM/Nortel hybrid using DMS100 protocol. Here are some good integration docs;

We are running the setup using a 61c.The connection's between the Nortel(NT5D12Ax Dual PRI cards) and Cisco are PRI's (using DMS100 protocol). We are running 25.40 on the Nortel.

Cisco Unified CallManager

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

From this good doc;

Hi Rob

thanks for that reply. To be honest my main concern is the fact of having to upgrade the Nortel system. Doesnt look like I have to now.
