[cisco-voip] CCM working with Nortel

[Lelio Fulgenzi]

There are a number of options available, it all depends on how quick you want it, how easy you want it and how much you want to pay. ;) Of course, traffic requirements are of concern too. 

Two basic options as far as I see: 

    • traditional TDM/PSTN gateway: T1 to T1, FXO to FXO, E&M to E&M. 
    • IP gateway: H323, SIP, etc. 

When we connected our HiCom PBX to callmanager we used T1 gateways and it works fine. We don't have some features like CallID but I believe that would be fixed with QSIG. But that costs money on the HiCom side. 

If you have these trunks available on both systems, it's usually the easiest to set up. Otherwise, if you have an IP enabled port on your Nortel box, an H323/SIP gateway might be better, but then you have to buy it.;)

CCM working with Nortel 

Hello all 

I have been tasked with see what the options are to link some systems (Cisco Call Manager and Nortel) together so we can dial across each one to the other for office extensions and such. 



I know this is a broad question, but can it be done ( I think so ) and what type of stuff is needed to accomplish it. 



If anyone has a broad overview that would be great.
