Hi all!
Cisco phone 7960 is not receiving an ip add. We have tried a factory reset but both methods do not seem to work. DHCP requests sent to the router from this phone are ignored. Other phones are all functioning properly. Port configurations are correct. please help troubleshoot
interface FastEthernet0/6
description To Internal voice and Data

switchport access vlan 131
switchport mode access
switchport voice vlan 11
mls qos trust device cisco-phone

DHCP settings for the router:

First Method:
Reset the 7940 and 7960 IP Phones to the Factory Default
In order to perform a factory reset of a phone if the password is set, complete these steps:
The phone begins its power up cycle.
The Headset, Mute, and Speaker buttons flash in sequence in order to indicate that the phone waits for you to enter the key sequence for the reset.
If you repeat a key within the sequence, for example, if you press 1223456789*0#, the sequence is still accepted and the phone resets.
If you do not complete this key sequence or do not press any keys, after 60 seconds, the Headset, Mute, and Speaker buttons no longer flash, and the phone continues with its normal startup process. The phone does not reset.
If you enter an invalid key sequence, the buttons no longer flash, and the phone continues with its normal startup process. The phone does not reset.
If you enter this key sequence correctly, the phone displays this prompt:
Keep network cfg? 1 = yes 2 = no
If you press another key or do not respond to this prompt within 60 seconds, the phone continues with its normal startup process and does not reset. Otherwise, the phone goes through the factory reset process.
Second Method:
Method 2

Faith,
I had a similar problem as this years ago with 7940/60s.
The phone had stopped sending tagged packets within the voice vlan.
Try these adjustments to your config
!
switchport access vlan 131
shut
no switchport voice vlan 11
switchport access vlan 11
no shut
!
See if the phone then finds an address and registers with the CME.
Then put the port on the switch back to normal
!
switchport access vlan 131
shut
no switchport access vlan 11
switchport mode access
switchport access vlan 1
switchport voice vlan 11
no shut
!
Regards,
Alex.

Is the phone in a seperate VLAN from the DHCP server? If so have you configured ip helper-address on the phone's vlan

Hi Alex!

Hi aokanlawon!
I think it's safe to say that the dhcp configurations on the router are correct since there are several other phones in the branch and all are connected to that one switch which is connected to the call manager!
But yes, the issue is with the ip adds. The phone was connected to a different subnet before. Tat was why I tried doing the factory reset! This helped because now when I do a show cep nei command on the switch, the ip address is gone! But the phone still cannot Get the right configurations.
We also tried changing the FTP server but we were unable to do it even after following the instructions on Cisco com

Alex!
Thank you!!! It worked. At the end of it all, i changed the access vlan back to 131.
