Summary:                    sip show inuse count is negative
Description: 
I have a bunch of snom 360s and asterisk-1.6.0-rc6. The snom BLF LEDs
monitor hints. However, the hints are getting confused and inverting state
sometimes. That is, unused extensions are being shown as in-use, and
vice-versa.

If I run "sip show inuse" during these times, I see entries like this:

steerpike*CLI> sip show inuse
* User name               In use          Limit
mjc_server                0               10
mjc_library               0               10
mjc_lab                   0               10
mjc_office                0               10
mjc_home                  0               10
* Peer name               In use          Limit
mjc_server                0/0/0           10
mjc_library               0/0/0           10
mjc_lab                   -1/0/0          10
mjc_office                0/0/0           10
mjc_home                  0/0/0           10

Note the "-1"! This is nonsense, and results in an "in use" hint:

steerpike*CLI> core show hints
                    601 at internal            : SIP/mjc_office&SIP/m 
State:InUse           Watchers 11

where the defined hint is:

exten =>
601,hint,SIP/mjc_office&SIP/mjc_home&SIP/mjc_lab&SIP/mjc_server&SIP/mjc_library


Somehow, the call count is being decremented by 2 after a hangup (from 1
to -1). Call counts should be clamped at zero, I would suggest.

This problem did not occur on the same system when we had 1.2.x and 1.4.x
running.

This also happens on 1.6.0.1.
