7940G handset does not respond when answering a call

[tangonm45]

I have had over 20 phones that I had to replaced over the past year that will not answer a call with the hand set. I can answer a call with the speaker key everytime but when I pick up the handset it does not repsond. Is anyone else having this problem. I have reset the phones to default settings and I have tried different software loads and it does not help.

Hi Nick,

I am just guessing here, but it seems like you are running into a common problem with the Hookswitch mechanism in Cisco phones. Have a look at the following doc:

Cisco 7900 Series Unified IP Phones

Best Practices for Cleaning and Troubleshooting Cisco IP Phone Hookswitch

http://www.cisco.com/en/US/products/hw/phones/ps379/products_tech_note09186a00801c0810.shtml

The recommended method has never worked for me, but the phones can be RMA'd.

Hope this helps!

Rob
