I have a 7961 that when you lift the handset it does not pick up the calls but works fine on speaker. Anyone think this might be something other than the hardware failing?

Hi there,

This is almost certainly a hardware problem with the Hookswitch. After deploying Cisco IP Phones for the last few years we (and many others) have found this to be the most common hardware problem. There is a "Best Practice" for cleaning the Hookswitch contacts (link below) that does work . Usually the phone has to be replaced/RMA'd.

If you don't have smartnet on the phone and you want to buy the parts to fix this let me know and I'll send a link

From this interesting Tech note;

WOW Rob, (+5 )

Self Cleaning Hookswitch Contacts

The hookswitch contacts design uses a wipe action to self-clean the contacts. Periods of nonuse of the phone allow air impurities such as dust and other contaminants to hinder contact performance, which results in intermittent operation. Press and release the hookswitch rapidly a dozen times or so to clean the contacts.

This is what Ive been doing for years.

I did not know about the document
