Change the access vlan to the data vlan, remove the switchport mode
trunk and it will work wonders; a non-dot1q client won't negotiate a
trunk and will get the native.  A phone will get a trunk and I think
that's what you want...

Subject: [cisco-voip] problem with phone getting DHCP address from
voicevlan

We have a number of new phones with a problem whereby they get a DHCP
address from the data VLAN not the voice VLAN. The only way to make it
work
is to remove the data VLAN, let the phone upgrade and then everything
works
after replacing the data VLAN even after erasing the phone
configuration.

Here's the specific phone load information:

App Load ID: P003030IMFG2

Boot Load ID PC0303010200

Version: 3.1 (MF.G2)

Here's my switch config:

interface FastEthernet1/0/40
 switchport access vlan 1220                  *this is what I remove to
make
things work*
 switchport mode access
 switchport voice vlan 3104
 srr-queue bandwidth share 10 10 60 20
 srr-queue bandwidth shape  10  0  0  0
 mls qos trust device cisco-phone
 mls qos trust cos
 auto qos voip cisco-phone
 spanning-tree portfast
end

I believe this only works with a phone attached. We want our ports to
work even without a phone.
