Nortel vs. Cisco IP Telephony deployment
|
|
| Steve G 2005-05-28, 5:45 pm |
| 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.
Background:
Deployment size will be 10,000+ phones at the end of the project.
All cisco Data network is existing.
40 WAN locations (Frame Relay) would talk to a Centralized CP and have SRST
enabled routers.
Any help would be great. +s and -s of the two products would be
appreciated.

| Overall I have been impressed with cisco CallManager and Unity. There have been things which I have not been pleased with, but let's be serious, every vendor/product has their weaknesses. 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. ;)
There are many features that are common place in other PBXs that for some reason are not in the cisco product, e.g. forwarding from secondary lines and PLARs, and require additional steps and or programming to make things work. 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.
The other thing I've found difficult to deal with is the lack of documented changes in the upgrade cycle. There are some documented changes but many are missing. 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.
Your deployment is similar to ours, except ours is a central campus with ~7500 phones. We've deployed 6 servers - publisher, TFTPserver and four subscribers, two each for our distinct groups - business and residence. An upgrade can take the better part of the whole day.
I'm sure others will join in in the discussion..... ;)

| Thanks for the reply Lelio. Today we are a Nortel PBX shop, so Nortel is
deffinatly a player. Perhaps the largest + that cisco has going for them is
their presence on a weekly bassis. By making hardware readilly available and
coming on site every week to help with LAB and design puts them
way ahead. I can't remember the last time a Nortel Rep was at our location
to see how they can sell us products in the future. cisco may not be
the absolute best in any 1 area, but they will support the heck out of
their products. At least that is my experience.

| Its kind of funny as I follow this thread. I am in EXACTLY the same
situation right now. Except we are small shop with big needs. We are
moving, have an old Norstar system that has been very reliable and
currently entertaining bids from Nortel and cisco for a VOIP system.
Cisco has broken their backs to get our business while Nortel is more
interested in talking bad about Cisco. cisco is currently in a major
lead for the very reasons you say below. I get the sense that Nortel
could care less.
It also seems to me that there are more 3rd party products readily
available for cisco systems than there are Nortel. Maybe I am wrong and
its just another point that Nortel hasn't let us know about.

| 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?

| I would agree. While we were going through the migration phase there was a
strong cisco presence. Unfortunately, we've seen that presence wane now that we
are fully deployed. Unless of course, we start talking about buying a new
product... ;)
We've picked up quite a bit of experience from the migration, so our requests
now have become quite a bit more complicated and are more design related, which
may be at the root of the problem, however, sometimes, we just need a pointer in
the right direction.
We've (or I've) been getting much of that from this list where I once got that
from our SE team pointing us to different internal cisco resources via
conference call, etc.
I like reading documentation like everyone, and expect that I have to do my
part, but a half hour discussion with a knowledgable rep can give you a
headstart that no documentation can.
