Avaya 1608 & 1616 Phones not Auto Booting

We have an Avaya phone system. We have 20 sites and all the site phones boot up, find DHCP addresses and the File & Call server just fine. Yesterday, we discovered that the main corporate site is not working correctly.

As long as the Avaya 1608 & 1616 phones stay connected, they seem to work just fine. If you unplug or reboot them, they seem to pull an IP address, but can't find the File or Call server. If you manually give the phones an IP address and put the File & Call server IP addresses in, it seems to work.

There have been Juniper switch & firewall updates recently, but not on this corporate segment. The File/Call server are on the same local network as the phones having problems. We had moved DHCP to a new server, and even rolled that back to the old server to see if that was the problem (since the old server had not been modified, we just turned off DHCP), no luck.

We restarted the MAS, but haven't restarted the CM server yet. Do you think that will help? If we do restart the CM, do all the existing calls drop? Any other tips?

Thanks.

Although no one responded.. We did figure out the problem.

If someone else has a similar issue, make sure that the DHCP server options are set to STANDARD not MICROSOFT.  That was the root of the whole problem.

Thanks.
