It depends on what kind of platform. For 3500XL/2900XL devices you will have
to set up the port/interface fro dot1q trunking and set the native vlan for
the data vlan. Non-Cisco IP phone such as Avaya are configure-able to send
vlan ID in their packet. For set command switches such as Cat4K, Cat6Ks all
you have to do is set the regular vlan for data and set the auxiliary vlan for
the voice vlan. This is done so you can plug-in a PC to the IP Phones data
jack. I have been told that Avaya advice not to use auxiliary vlan for now
since they have not tested but I find it to work just fine. But you can also
trunk the port using dot1q and making the data vlan the Native vlan. This
helps?

Subject: Problem relating to Interoperability of Cisco IP phones with
non-Cisco switches
How do you set the operational VLAN and admin VLAN on a Cisco IP Phone if the
switch you are connecting to network with does not support CDP? Normally a
Cisco IP phone learns about what VLANs it is using through CDP communication
with a Cisco switch.
I wonder if you can have the CallManager tell the IP Phone what VLANs it is
using. I have not found anything indiacting that this can be done. Even better
would be being able to set the VLANs on the phone itself.
Thanks in advance,
