<BODY>
After working diligently with techs from two separate ATA manufacturers, we're pretty convinced that the process of sending RFC2833 DTMF digits outbound, from Asterisk to an ATA, is broken.<BR>
<BR>
Note that I'm not saying that the code in Asterisk -- ast_rtp_senddigit() -- is necessarily broken. We have one vendor claiming it is, and another saying that they don't handle inbound RFC2833 well in the first place.<BR>
<BR>
What I'd really like, is to apply a patch so that, instead of calling ast_rtp_senddigit, we instead generate and send an inband DTMF tone (for a duration of, say, 250ms).<BR>
<BR>
Can anyone please advise a shortcut to do this? I don't mind getting my hands dirty (dirtier) with the Asterisk code, I've gotten this far hacking ast_rtp_senddigit to pieces and back, several times over.<BR>
<BR>
Thank you,<BR>
<BR>
