Cisco IP phones integrates with Nortel CS1000 VoIP?

[TechCUTelecom]

Hello,

Have anyone done this kind of intergration between two systems? Cisco VoIP and Nortel VoIP?
I current have Opt61C with Succession 3.0 (CS1000M) and Nortel VoIP phones.
The company wants to try Cisco IP phones. If I want to intergrate Cisco VoIP to the Nortel environment, are there any major issues I should concern?
I know a few issues such as:
* CallPilot Voicemail Message Waiting Light.
* Call ID will disappear when transfer calls from Cisco to Nortel or the other way around.
* Blind transfers initiated from the PBX are not supported.

If you already done this intergration, Can you tell me some of your experience about this project? Pros and Cons. Recommend or not recommend.
Thanks in advance.

Are you asking about having the Cisco IP Phones directly connect to the CS 1000, or putting in a Cisco Call Manager (with the Cisco IP Phones connecting to it) and connecting the CCM to the CS 1000? Those are two entirely different scenarios.

Put in a Cisco Call Manager with Cisco IP phones connect to CS1000.

Curiosity question.. Why are you doing this? What does the company think they can do with Cisco IP Phones that they can't do with Nortel IP Phones?

They just want to try something new. Since they heard so much about Cisco VoIP. Also most of our routers, switches are Cisco.

The lemming effect.. Unless you've got money to burn, trying something new without a clear business reason for doing it makes little sense. Get "they" to explain what they hope to achieve.

Check the market share data and you'll find that the vast majority of people also have "most of our routers, switches are Cisco". That doesn't prevent Nortel VoIP (as well as Avaya, Siemens, Mitel,...) from working very well over that infrastructure.

I WORK ON BOTH, AND I REALLY DON'T THINK TO MUCH ABOUT CISCO. THERE ARE JUST TO MANY THINGS THAT THE CALL MANAGER CAN'T DO, IF YOU NEVER HAD A TELEPHONE SYSTEM BEFORE IT MAY BE OK

I have a Business case that requested to interface Nortel CS1000E and CCM + multi gateways. It was a must to integrated it with fully networking features working. Because of the CS1000E don't have any physical trunk, and the customer want to use its Cisco network to interact with, we gain success after 6 months working and Nortel support.
A very strong knowledge of the Cisco environment is required. A strong understanding of IP trace debugging is also necessary. Nortel Rls 4.5 + SS 4.50.75 at least is necessary. 2 specific Nortel patches were necessary: 1 for SS, 1 for CS. 2 different trunks on the Cisco side were necessary: 1 defined as Gateway working with GK, 1 defined as IP Trunk direct to CS (if i remember, because CCM is not my cut of tea...)
Basic calls works fine very quickly. Problem appears when CFW, FDN, HUNT, TRN, Blind TRN, Voice Mail on Cisco side, PCA, and so on....
I don't think you will achieve prefectly unless Nortel will not provide new patches on rls 3.0
Tell me just details you want to know and i will try to help.

Save your time and money! Buy 1140 IP phones w/ bluetooth headsets and an Application Gateway. Then get MS Live Communication Server and do unified communications. Cisco is just legacy VoIP.

If its because you have Cisco data then I would say loose teh Cisco data and install Nortel routers and switches. They are cheaper, faster and better.

BTW, the 1000E does have trunks. Analog directly on the media gateway and PRI's through the 1000T or an AudioCodes PRI gateway. In Rls 5.0 there will be PRI support directly from the media gateways.
