[asterisk-users] many sip dialog/ opened channels.

[Catalin S.]

Hello,

I'm using asterisk with 84 extensions (aprox 45 always connected). When i
look to the opened channels i sow many channels opened without reason even i
don't have any active calls.
Is there someone else that en-counted the same problem? Is there any fix to
this bug? I have the following settings:
