      Status: Waiting for Feedback  (was: Triage)

Where in the RFC do you see the language about ignoring signal duration less than 40ms from the perspective of the out of band DTMF?

It reads as though it is referring to the detection of the inband DTMF and conversion into out of band DTMF.

>          Components: Resources/res_rtp_asterisk
>    Affects Versions: GIT, 16.10.0, 17.4.0
>         Environment: CentOS 7.6

> The minimum RFC2833/RFC4733 DTMF signal duration should be 40ms, however Asterisk processes packets with the duration less than this.
> Any packets less than 40ms should be discarded and therefore ignored when using the Read and Background applications.
