switch traffic and ip phone

Hi,

I have a D-Link switch  connected to the "PC port" of an IP phone. It often causes the IP phone to unregister. I first thought it was BPDU Guard that err-disables the port, but with my actual config, I no longer am sure:

TNSWACCS01A1#sh run int fa1/0/13
Building configuration...

Current configuration : 250 bytes
!
interface FastEthernet1/0/13
description --- Mahmoud Chaabani ---
switchport access vlan 11
switchport mode access
switchport voice vlan 2222
priority-queue out
mls qos trust cos
spanning-tree portfast
spanning-tree bpduguard disable
end


TNSWACCS01A1#sh int statu err

TNSWACCS01A1#
TNSWACCS01A1#

any idea?

Why have you got a switch connected to the PC port of the phone?

This user has many PCs in the same vlan 11, and only one wall jack is available to him.
