asterisk users - Feb 2007 - SIP interface status and calllimit

There is an issue when using call-limit for a SIP interface in
sip.conf.  The call count does not properly reset when some calls
end.  The problem happens regardless of which side of the connection
ends the call.  It happens on all calls including calls from SIP
interface to SIP interface (with no reinvite) within the same Asterisk
server.  I have not been able to determine a definite pattern.  I can 
call from one interface to another 50 times before it happens and 
sometimes it happens after only 2 calls.

We have to enable call-limit for our customer service queue agents so 
that the ringinuse option in queues.conf will work properly.

Has anyone else seen this issue?  Any ideas?

Thanks,
James Fromm

This doesn't really help you, but might help others when deciding how to 
design their Asterisk system.  On our phones we set call waiting off and 
each line appearance registers as a separate SIP user.  This avoids all 
this silliness with call limits, group limits, etc.  This also allows us 
total control about which call appearance a call shows up on, roll over 
and hunting features, etc.  It does require a little more work in the 
dialplan, but for our needs it is well worth it.
