Hi All

I’m getting tens of thousands of these messages ever hour in the Asterisk CLI for Asterisk 13.22.0:

If an invite is non-critical, why do it then?

What is the purpose of a “non-critical” invite.

My server mostly works, with occassional channels that get stuck and need to be hung up manually, but otherwise is working fine.

I’m trying to identify what a non-critrical invite is, and if it is non-critical, can it be turned off somehow?

Since it is explictily shown as “non-critical” – it means it can be dispensed with, as it is non-critical.

Clearly, it IS critical, since it exists, but why the strange semantic of calling it “non critical” – why do something that is non-critical and therefore not necessary.

Thanks!

Stefan
