Summary:                    Hints/extension state random in 1.6.0.15
Description: 
I am getting lots of these:

  == Extension Changed 771[Hints] new state Ringing for Notify User
785-000413233e36-1 
  == Extension Changed 772[Hints] new state Idle for Notify User
792-00041327d17e-1 

The hint extension seems fairly random, and every time it obviously
notifies all watchers. The state also seems random. Nothing is happening on
the system to explain this behaviour.

The problem appears on the three different production systems temporarily
running 1.6.15. My test system with only 4 connected phones does not
exhibit the problem, unfortunately.

1.6.13 is fine; I have downgraded back to that for now. 1.6.1.6 is fine
too.

I tried reverting these two changes: r205414:r205415 r204753:r204754. No
improvement.

---------------------------------------------------------------------- 
I am able to reproduce the problem on one of our test systems in
1.6.0.16rc1! I did the following:

a) started asterisk
b) connected to the console with asterisk -rvvvvvvvvvvv
c) made sure the phones were registered, and that both hints for 202 and
204 were correctly in state Idle.
d) Made a call from 204 to 204, but cancelled the call before it was
answered
e) Now both phones are stuck in State:InUse&Ringing

I have uploaded a dump of all sip traffic from the time Asterisk was
started and till the end of the test, along with the console output from
the test. Let me know if you want sip.conf and extensions.conf as well.
