[asterisk-dev] DTMF Gereration duplicated. Why?

[Paul Cadach]

Hello,

I'm not sure but at least RFC2833 allows to not mute audio stream when sending RFC2833-coded DTMFs. But if you have enabled inband DTMF detection together with another sort of DTMF information - you will have duplicates, of course.


WBR,
Paul.

  Hi,

  no, I don 't... My callback receives from hardware the DTMF signal as soon as it is detected. Checking another channels implementations, I think I need to *mute* my channel during dtmf... Is it correct?

    Do you have support for variable-length DTMF with BEGIN and END events of DTMFs?

      Hi,

      In my custom channel, when it detects a DTMF, it sends a AST_FRAME_DTMF to Asterisk. My problem is when I have to bridged channels. When the user press a DTMF in channel A, channel B receives it duplicated (or splitted??). 

      My *send_digit* callback always returns -1 to avoid Asterisk to generate DTMF.

      Someone has an ideia about?

      Best Regards
