test it out with rfc2833 with sip since it is the most common of them all

Ok, with SIP you can send the DTMF in 3 flavors. You need to know how
your SIP telephony gateway providers send and expect the DTMF. You
configure that in Asterisk file sip.conf, look for the peer parameter
"dtmfmode", valid values are:

dtmfmode=info
Use SIP INFO messages to send, this is out of band

dtmfmode=rfc2833
Actually i dont know, but check RFC2833 :)

dtmfmode=inband
The DTMF digits are sent in the same stream that the audio. This means that
if the audio codec is of low quality, DTMF may not pass.

dtmfmode=auto
Asterisk is supposed to detect the correct DTMF mode to use, actually
I havent used this one, but you can give it a try :)
