I'm looking for a solution to the following problem, and would appreciate any help somebody might be able to offer me...
We're currently using the Avaya 406 with 5602s, and, at the office, it works fine. We have the 406 doing DHCP for all of our IP phones, and it works. When trying to deploy these phones remotely, and using DHCP over VPN between 2 sonicwall devices, the phones will not pull an IP from the DHCP server. It seems that the Avaya DHCP server will not serve leases via a relay - I can see the relay IP requesting DHCP leases via ethereal. Also, when I change the DHCP server address on the sonicwalls, the phones do get IPs - just from the other DHCP server, on the other network - so I know the configuration is working. Is there a way to tell the Avaya DHCP server to stop doing that, and to honor any request? If not, then, is there a DHCP server that you'd recommend to replace the Avaya internal one? Requirements dictate that it allows for adding option 176 to the DHCP server, for use with IP phones, which a lot of the freeware ones do not. Windows XP is what our voicemail server runs, and I have a linux server on the network. I'd be happy with anything that will run on either.
Thanks!
