ASTloop/ASTblind : hack or feature ?
Posted: Mon Mar 11, 2019 7:06 am
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 :
Thank you
