[asterisk-dev] Many sip dialog/ opened channels.

[Eric Wieling]

SIP channels are created of a variety of reasons.  The ones below are created because of a registration this is normal.  To see a list of calls (channels associated with a call), use "core show channels"

I find it odd the peer is shown as <guest>.   Are those IPs listed actual real IPs or did you mask them?  If they are real, I'd say your server is under attack.

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:
