[asterisk-users] DMTF Mode

[Dan Journo]

I'm really struggling with this DTMF issue.

In order to test it, I've tried a few different providers and DTMF RFC2833 does work with any of them, even though a few of them insist that it is.

Is this a bug with 1.4.36?
Has anyone else experienced this problem?

The Asterisk CLI is showing the DTMF signals properly, the tones just don't get repeated to the opposite end of the call properly.

Any help would be greatly appreciated!
Thanks
Dan
