CM 4.0 is not available on product upgrade tool yet. Call your SE and give him your SAU contract number is he requires it to get the media for 4.0. I just upgraded our system that currently runs about 500 phones to 4.0. Upgrade was smooth and things are working great! Except that IP communicator does not work, have to wait for SR 2.
Also did a new IPT deployment on 4.0 for about 200 phones, no problems there as well. Since the product is pretty stable, I am doing all my future installs next month with 4.0.
If any of you plan to upgrade, keep the following things in mind:
1. The way voicemail ports are setup is completely changed in CM 4.0. A new feature called line groups is introduced and voicemail ports are linked to a line group so they can be hunted. Voice mail pilot requires a route pattern that routes to the voicemail port line group.
2. IP Communicator no longer works.
3. Changes in H323 gateway configuration (if you have your gateway configured as h323, if MGCP, no worries).
4. Update TSPs for softphone and outlook dial to work.
5. Attendant console needs to be reinstalled as a new feature called broadcast calls has been introduced (basic queing).
6. If you have CAR or ART installed, uninstall it before you continue and make sure CDR database is not deleted, just the tool is.
AdmanOK, I agree with you by getting your CM upgrade using SAU, its better to be safe than sorry. Cisco is going to get strict in their CM licensing in 5.0, they will make it like unity where PAK is tied to the MAC address to get a license key, so it would be tough for people to buy it from EBAY or wherever.
Computerhigh guy, I agree eBAY gets you things cheap, but just so you know, you can get a 3550-24 SMI for 1200 bucks as well, brand new from a reseller... how? Something called Flip the Switch program that gets you huge discounts on 3500s switches, you just have to know the right people... and you need to take your AM out at lunch more often
