[cisco-voip] Hookswitch problems on IP phones

[Mike Armstrong]

We're starting to see problems with the hookswitches on 7910 and 7940 
phones.  First occurrence was a couple of weeks ago, now 2 more in the last 
week.  Is this a trend, I wonder?  (Phones are about 5 years old.)  Symptoms 
are that when the phone is lifted off-hook, the switch only goes off-hook 
for a brief instant, then goes back on-hook.  The caller only hears a brief 
click followed by a dead line, and the callee gets a bum rap for hanging up 
on his callers.  One of my guys suspects the spring in there is weakening. 
Is anyone else seeing similar problems?
