Handset not active when taken of hook on incoming calls

I got the problem that sometimes on incoming calls on to an IP Phone (7940/60) when i take the handset

the call is not active on the handset. Via the Softkey "Answer" i could take the phone but only on the speaker.

CCM is 3.3(3)sr 3

Phoneload is P00305000301

Did somebody have some issues like this?

Thanks for any information regarding the problem.

Re: Handset not active when taken of hook on incoming calls

This is a problem with the IP phone hookswitch. Most likely you will need a replacement for the phone. There is a Cisco internal field notice which you can give to the TAC engineer when he takes the case.

Thanks for you feedback but i can not get access to

the link you posted.

Domain seams wrong (www-tac.cisco.com).

So maybe you can post it again so i can access it.

Thanks

You cannot access that link, neither can I because it belongs to Cisco's intranet. The reason I gave the link is for the Cisco engineer to reference it if you open a Cisco TAC case.

Re: Handset not active when taken of hook on incoming calls

Since the field notice is internal, I cannot give you more information. This is a manufacturing defect.

Engineering failure analysis has determined that out-of-spec vendor components may have made these early phones susceptible to hookswitch failure.

We have spent several hours troubleshooting this issue, hope you don't have to do that.

You can find at least part of the info here:

http://www.cisco.com/warp/public/788/AVVID/hook_switch.html

If working the hookswitch a dozen or so times manually doesn't clear up the problem, you will have to go ahead and RMA the phone.
