Description:Hi,
does Asterisk supports fax detection through faxdetect option if CNG signal is coming in RFC 2833 RTP Event? I have WorkCentre 3220 trying to send FAX to may Asterisk 11.16.0 (faxdetect = yes). The CNG tone is coming to Asterisk through RFC 2833 RTP Event, and Asterisk seems to ignore it, event when i sent DTMF mode to RFC. When CNG comes in RTP stream everything works fine.

I'm attaching trace from this scenario.

So what's the point of  Information Request Type? :)

The Information Request type is a legacy left in the issue type scheme for the project.

Ok, can You tell me who can decide that this is or is not a bug, or maybe a new feature? I can tell for sure that Asterisk does not detect Fax CNG tone through faxdetect option if this tone comes in RFC 2833 RTP Event.

It would be a new feature. The res_rtp_asterisk module does not currently support it.
