My PC has to connect via Data port in IP phone and not to switch directly???

i have a Cisco phone 7941 connecting to a Cisco 2960 switch port. My voice vlan is 50 and data vlan is 1.

the corresponding switch port settings are:

interface GigabitEthernet1/0/30

switchport mode access

switchport voice vlan 50

no snmp trap link-status

spanning-tree portfast

My PC is hooked in the data port of 7941 phone. It is fine.

The problem is, when the phone is removed, I use the same cable to connect PC to the same wall port hence the same switch port,

the port shows

BNEPSYS-SW09(config-if)#do sh int GigabitEthernet1/0/30

GigabitEthernet1/0/30 is down, line protocol is down (notconnect)

I then remove switchport voice vlan 50 and it means it is in data vlan 1, it still shows the same status.

although down/down usually means physical problem, i did change the cable/switch port/pc, the problem is the same.

Does the PC have to connect via IP phone port and it can't connect to switch port directly? what's wrong here?

any advice will be much appreciated.

have you tried setting the port speed to full 100?
