Nortel to Cisco migration - PBX Info :: Your Free PBX, PABX and Telephone Information Resource

We currently have 7 Nortel systems deployed throughout the US and Mexico. We have a Nortel CallPilot voicemail system. Two sites are building new facilities and we are considering implementing Cisco IPT there. We would put a call manager cluster at our main site (where
voicemail is) and make the other site a remote (I think there are 2 flavors of Cisco remotes). The 2 sites would be connected via MPLS.

If you have transitioned from Nortel to Cisco I would be particularly interested in your experience as it pertains to:

System capabilities and features

Ease of implementation

Support and maintenance

Uptime and reliability

Problems and challenges you had to overcome in transition

Do you use Cisco for all of your Data gear as well? That is an IMPORTANT question to answer, as it can seriously affect system performance and reliability.

What does Call Manager offer you that your Nortel system does not? There must be a reason to want to make a change... I assume you want to connect all the sites in an MPLS cloud and IP telephony makes the most sense to do that.

I came from a LARGE SCALE Call Manager deployment (65+ sites) through an MPLS cloud. I have lots of experience in some of the ups and downs...
