Hi,
Although I apply the patch, I don!t have any DTMF event when remote device
sends dtmf. What should i do to have MEDIA_REMOTE_DTMF event work with sipxtapi
3.2 stable branch.
Regards,
Mert
Hi,
here is a patch for the DTMF problem.
I am still trying to figure out how to best solve the supervised transfer
problem.
