This is an update to a fairly old post I made a few years back now providing an example dhcpd.conf configuration file for use in an Avaya (formerly Nortel) IP telephony environment. I was recently working on a few things and discovered that the Avaya IP phones ignore the next-server option within my dhcpd.conf file. A few tests and I quickly found that I needed to define the tftp-server-name option with the IP address of the TFTP server (see the global section of the dhcpd.conf file below).
If time allows I hope to post an update in the very near future covering the new Nortel-i2004-B option string. While working with the SIP 4.0 software release in the past few articles I did learn that the Avaya SIP IP phones can utilize a new DHCP vendor class, Nortel-SIP-Phone-A which can allow you a little flexibility when configuring them via DHCP and TFTP.
In the same file below I setup four DHCP scopes; one for 2111/2212/6020/6040 wireless handsets, one for i2002/i2004/1100/1200 series IP phones, one for 1100/1200 series IP phones running SIP and one for all other devices (laptops, desktops, etc). Just a quick note about the example below, you’ll notice that I have no pools in the 192.168.1.0/24 network. All the pools are in the 192.168.25.0/24 network.

Hi Machael, I need your help to configure Avaya Wireless phones 6140 with w2245 and BCM 400(Call manager) Microsoft windows Server2003 R2 (DHCP Server). I need to configure Option 60, Option 151 in DHCP server so that Wireless Phones can see W2245 while comming through DHCP server, When the handset is in DHCP mode it gives “No SVP IP” error.
Pl. help you are my last hope Avaya support is hopeless.
Waiting for your reply i need to implement tomorrow.
