Unexpected control subclass '-1'

[binbash]

I've installed two vicidial installations and seemed to always find this error.

Can someone tell me why this keeps showing up on the CLI ?

I tried to google it, but could not find anyone with the same problem

Thanks

That is pretty much normal as well. Another Asterisk warning that doesn't seem to cause any issues unless you see hundreds of them per second.
