7940G handset does not respond when answering a call

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.

Re: 7940G handset does not respond when answering a call

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

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

Hope this helps!
