The bug report certainly describes the symptom...  I will look out for 
it happening again and next time, I will have someone try a couple of 
these, probably beginning with the wall mount tab thing... I suppose one 
could add some weight to the handset, too.

Thanks again!

            CSCto78441 Bug Details

*7962 phones are going off-hook and then on-hook 400 milliseconds later *
*Symptom:*
7962 phones are going off hook and then on hook 400 milliseconds later, 
which prevents the user from answering the call properly. This behavior 
can be seen in the SDI traces:

11:33:42.540 |StationInit: (0000030) OffHook.|1,100,49,1.584290

and then back on hook roughly 400 milliseconds later:

11:33:42.981 |StationInit: (0000030) OnHook.|1,100,49,1.584297

**Conditions*:*
This can occur on 7942 or 7962, and is more likely to occur when the 
phone is sitting at a steep angle and especially with a sidecar attached.

*Workaround:*
1. Invert the wall mount tab to be in wall mount mode.

2. Reduce the angle at which the phone is sitting by two notches. This 
may not be possible if a sidecar is mounted.

3. Do not use a handset, use only a headset.

4. Open a case with Cisco Customer Service or Cisco Technical support to 
have the affected handsets replaced.
