Ok.. I am forwading to a Big project. I haven't worked with Nortel EPBX and phones. So I am to confirm abt the configuration before jump to the site. normally this command,
switchport priority extend trust - instructs the cisco voip phone phone to trust on priority set bey attached PC to phone and pass the traffic unchanged. Is it needed for nortel phone also. What is the setting on Nortel phone?
Pls reply..
From a document i read, it looks like the Nortel phone will trust the dot1p settings from the downstream pc by default. So, you dont need this command. However, the article also says that for the Nortel phones to work, the switchports have to be configured explictly as trunk.
Iam only familiar with Cisco IP phones and hence might not be able to help much. Hopefully there are other experts out there with Nortel IP phon experience.
Dont think the switch port needs to be explicitly set to trunk. Voice vlan / Aux vlan configuration should work.
And to TS, your config looks fine. However, I am not sure if the Nortel phone will let you configure static IPs on startup. The earlier models had to boot using a DHCP IP before we could access the configuration screen!

If you just want to plug an unconfigured Nortel IP phone to the Cisco switch and expect it to a DHCP address from the Voice pool, this will not work. Basically, the phone will pull an ip from the data pool just like any other pc or workstation. Usually these phones will get an ip from the data vlan and look for a specific DHCP option (176 for Avaya phones, Option 144 or 191 for Nortel phone) to obtain the vlanID of the voice vlan. However, since you are using the switch for DHCP, i dont think you can configure it for these DHCP Options.
