Hi, 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.
