1200 series phone

[mevans1974]

Hi We have a 1200 IP phone on a BCM with Nortel 4526T-PW switch
the problem is we can't get the switch to work correctly
The customer has 2 Vlan on their network Vlan1 Data Vlan 3 Voice

all the phone that is plug into the core switch is working with no problem any phone that is plug into the Nortel switch do not work..

I setup the 2 vlan in the nortel switch and I put all the ports in both vlan but I don't think the trunk port is working correctly.on the port that is coming form the core switch

You sound correct. The port that connects the core to the nortel has to be a trunk port with both VLAN's assigned. Could be on either port, the core or the nortel. What type of core switch?

The core switch is cisco 4500 series L3

Do you have the command to setup trunking on the nortel switch..
