Alex,
OpenSIPS is a SIP proxy. DTMF method you're mentioning is RTP-based. So,
you need to make sure you're passing RTP streams correctly. And on
client side this should be configured as well.
But just to highlight again, DTMF (unless SIP INFO) is not a question
related to OpenSIPS.

Hi All. We have an issue where when we send a call to our client, they say
the DTMF is not working and we've confirmed that to be the case. Our
carrier is sending over RFC2833. How can we set the DTMF mode in
OpenSIPS? What is the recommended approach?
Thank you,
Alex
