[App_rpt-users] DTMF digits on IaxRpt

Fri Aug 15 01:48:24 UTC 2014

Somehow this got off on rpt.conf while the original question was about iaxrpt a product written by xelatec which is not open source. If it was someone could probably fix the problem. You need to complain to the developer. The last time iaxrpt was updated was Jan 10, 2011. There are a lot of neat features that could be added to that application like adding the missing DTMF keys and including the ability to control PTT from other windows applications and not have it unkey off focus. If that were done it would work very nicely for digital interface application like fldigi. If you go to the iaxrpt website and register you can use the "call me now" tab to call one of the developers. Whether that works or not is another story but I suppose you could always email at the contact us tab.

Asterisk and app_rpt decodes the A-D keys very nicely. Run the asterisk client and press the keys, you will see them decoded.

Asterisk's "dsp.c" (even the old version in the app_rpt fork, I believe) does indeed already decode them at no additional cost, so I too would have expected them to just come along for the ride.  Does some other part of the system filter them out?

Who cares why -- although I can think of a dozen use cases without even trying hard.  Besides, it costs absolutely nothing when you're already doing the other digits.  Let the man have his tones, I say.
