ASTloop/ASTblind : hack or feature ?

[tarikzz]

Hello,

I can see weird outgoing calls, related to ASTloop/ASTblind.
I read that these IAX users are legitimate but i cannot understand why they are currently being used for what seems to be outgoing calls from my server, destinated to the same server (kind of loopback calls).
I have sometimes a dozen of calls like this at the same time, on a particular extension (usually 3117, and sometimes another one)

Also, these calls are placed while i don't even have any agent using the 3117 extension.
So it doesn't seem to be a legitimate conference feature or something like that.

Is this behavior normal ? Here are opened channels related to this extension :

Code: Select all

vicibox8:~ # asterisk -rx "core show channels"  | grep 3117
IAX2/127.0.0.1:41569 3117@default:1       Up      Dial(SIP/3117,60,)

Thank you

They are used primarily for blind monitoring of agents. Are you doing that on your system?

[tarikzz]

Thank you Matt. Did some tests and yes, that was the blind monitoring system.

I had multiples calls with the same extension because the supervisor was monitoring the agents one after the other, which was opening a new line in Zoiper, putting the other ones active - on hold.

Thanks again for the quick help
