Check the cord between the handset and the phone. That's the thing that goes the most on Cisco phones.

Hi Fernando,

what is the firmware version u are using?

I was just refering the BUG.

No sidetone on 6941 handsets

CSCtr37033

Description

Symptom:
On 6921 and 6941 model phones users do not hear sidetone. Side tone is the very short tail length (<~20msec) echo heard on the handset earpiece. Side tone provides reassurance to the user that their voice was picked up by the microphone.
Conditions:
On incoming calls to 6941 handsets the user is not able to hear any of their own voice through the earpiece. It appears to work correctly on outgoing calls, and other phone types.
This affects 6921 and 6941 model phones running a load earlier than 9.2(2)
Workaround:
None. Upgrade.
