Martin,
I have implemented a Call Manager Express system which I must say was very
simple with basic CVOICE-type knowledge. It is very reliable and cost
effective for a small location under 200 phones or so.
Have you looked at the CCME product?

If you are migrating from an existing solution to a new solution, then I would strongly suggest evaluating what your current system can do now and what the proposed system can do very carefully. Take promises of features with a grain of salt and don't expect those to come to fruition any time soon - plan on deploying what you can see in front of you. And don't underestimate the importance of any one feature - or in our case any one person that might be using that feature. ;)

In the case of forwarding secondary lines they will point you to the user's phone configuration web page - since there is a solution, there has been little effort to including that as a feature. In the case of a PLAR, you have to create a special class of service for that phone which only contains one dialable pattern - a lot of work if you have a lot of PLARs with different destinations. Other systems have a dialdown field parameter. In actuality, many of the features you might need require seperate classes of service definitions to make them work. That's one of the things that I don't like. Not scalable in my opinion.

Phone upgrades in particular seem to change quite a bit of the asthetics of the phone without any sort of documentation whatsoever! Enterprise and System Parameter changes are not documented in new releases so you have to sort through them to see what might be missing or added - with over 300 of them, it is time consuming.

> Hi Again,
> Does anyone have experience with comparing Nortel's VoIP solutions with Cisco's? I am currently evaluating the two beasts and so far have only got my hands on Cisco's CCM 4.0(1) and a Unity Server. I must say they are pretty slick products. I have no experience with Nortel equipment as of yet, and would like to know if there are any caveats to either one that would rule it out of the comparison.
