Good Luck! Hi Radman,

Good Luck!

Then they can roam to any campus where DHCP will assign them a local IP address and local 2245 gateway but the phone will connect to their "home" Call Server across the wide area network. We've actually been very successful in our deployments. The early firmware for the 221x wireless phones didn't have the partial DHCP option available so we pushed Nortel hard to get that feature set into the phone firmware. It sounds like your physically moving folks between Call Servers? If you're doing that you'll need re-configure the wireless phone. I'm not sure if Nortel is looking to deploy the Nortel-i2004-B DHCP option string on the wireless phones which might give you the ability to remotely reconfigure the device. Good Luck! Hi Renier,

For some reason the users love to move between sites and with the full DHCP option on, its frustrating because you have to go out and change the users Node ID on the phone to the specific site they moved to. Is there a script you can write for when a phone changes from site on a HA system that it can automatically assing the site's Node to the phone also? Hi Micheal

Just be aware of the following post I made recently, <a href="http://blog.michaelfmcnamara.com/2008/08/adac-and-vlan-configurations/" rel="nofollow">http://blog.michaelfmcnamara.com/2008/08/adac-and-vlan-configurations/</a>. If you make VLAN changes after you enable ADAC you can run into issues later on. Good Luck!

I'm planning to upgrade the 5520 to version 6 (after learning from here that was already out). Already downloaded it. Let's hope everything goes according to plan! Let's hope BCM450 behaves as well as CS when it comes to ADAC. Dan.- Thank you very much! I’m planning to upgrade the 5520 to version 6 (after learning from here that was already out).

This document is still applicable for the most part. If you are running software v5.1 or later on the ERS5520 then you don't need to work about the MAC address ranges. Let me know if you have any questions. Good Luck! Hi Dan,

Every since release 2.3 (latest release that just hit the streets is 3.0) you can configure "almost all" the options via DHCP. There are obviously a few options you can't still configure via DHCP because the phone wouldn't be able to get a DHCP response. <br /><br />You can read my post entitled "<a HREF="http://michaelfmcnamara.blogspot.com/2008/05/nortel-ip-phones-unistim-release-v23.html" REL="nofollow" rel="nofollow">Nortel IP Phones - UNIStim release v2.3</a>" for a list of all the DHCP options.<br /><br />Thanks for the comment!
