Hi all:
I have a cisco 2960 and NEC IP phone. Situation is like this. When I configurated the IP phone to vlan 1 (the default vlan), the phone via IP PBX (NEC SV8300) can work, but when I configurated the IP phone to a vlan 2 or other vlan, the phone can't register. But it can ping the IP phone,and the IP phone is using a static IP addres.
Solved! Go to Solution.

Hi,
1) Can you share the config of your 2960 phone interfaces ?
2)When you say you CAN ping the phone in a NON vlan 1 configuration
where are you pinging it from ?

Hi,
When you change your phone to use a different vlan you
are probably invoking 802.1p vlan tagging
You could try changing the set up of your 2960 interface
Lets say you are going to use Vlan 2 for voip
Try this :-
!
int gig0/0
shut
desc ** NEC IP Phone Port ***
switchport host
switcport voice vlan 2
no shut
!
This will tag the voip type packets to your phone as VLAN 2
You wil also need to make sure that the default gateways ( may be this your 3750) can route between vlans
Hope this helps
