The 7935 IP Conference Phone is not registering, which causes problems with the voice VLAN

Core Issue

The concept of voice or auxiliary VLAN does not directly apply and can cause problems because the Cisco 7935 IP Conference Phone has no 10/100 port to connect a PC to other similar Cisco 7900 Series IP Phones.

Resolution

To resolve this issue, remove references to voice VLAN or auxiliary VLAN from the port on the switch that the Cisco 7935 connects to and put that port in the VLAN whose number corresponds with the voice VLAN.

This is the configuration for Cisco IOS  Software products:

configure  terminal

interface 0/x

switchport access vlan z

no switchport voice vlan z

no switchport mode trunk

no switchport trunk encapsulation dot1q

end

This is the configuration for Catalyst Operating System (OS) products:

set port auxiliaryvlan x/y none

set vlan z x/y

set trunk x/y off
