[OpenSIPS-Users] DTMF Issue

[Ihor Olkhovskyi]

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.
