gdixon Posted May 27, 2016 #1 Share Posted May 27, 2016 Hi, Just wondering if anyone has ever been able to relay the DTMF tones using rfc2833? We have a scenario where calls come in through an internal SIP trunk from a skype for business mediation server. The calls are relayed out through our external PSTN SIP trunk. Call connects and works however DTMF tones when pressed on our skype for business enterprise voice client does not relay through the PSTN SIP trunk. The Swyx server receives the DTMF tones from the skype for business mediation server but does not forward them to the outbound leg of the call. Cheers Link to comment Share on other sites More sharing options...
