I've been seeing this lately on Cisco 7940, seems to happen on two of  
the three at a location I deal with. They worked fine for years and  
then all of a sudden this just started happening. Rebooting the phone  
will cure it for a period of time, but it always comes back, and  
always to the same two phones (although not always at the same time).  
I don't think anything changed when it started happening, but I can't  
say for sure.

It may also happen on a Polycom at that location as well, reports on  
that one have been sketchy, so I can't be sure it really is versus  
they are hearing a 2nd call ringing and just think the phone is stuck  
ringing. (I do know for a fact it happens with the Cisco and is not  
simply a 2nd call).

I had figured it was the old version of Asterisk I'm running and the  
fact that the server has had several power failures so who knows the  
health of the machine and install. But if it is happening to others,  
my assumption may be wrong.
