[OpenSIPStack] Double DTMF

[Whit T. <de...@wh...>]

I'm trying to play DTMF tones out of ATLSIP, into asterisk and out to the
PSTN via a SIP trunk. I know there are several dtmfmode configurations to
use such as info or inband but I'm getting some strange behavior. 9 times
out of 10 I'll get double tones when using SendINFOTone. Then, using
SendRFC2833Tone it sometimes doesn't even play anything at all to the called
party. I tried using an X-Lite Softphone to eliminate it being an asterisk
issue and it works fine so I wonder if there is something strange happening
here with ATLSIP. Any suggestions or is anyone else having these problems?
