In pstn when I play a sound file which contains dtmf digits, FS produce
dtmf digits which can be detected on other end. I use sangoma card.
but when I play same file, on sip. no dtmf is generated or detected on
other end.
it simply play a beep sound ...

Can I play a sound file and generate DTMF digits on SIP.
