Hi all, I am facing a issue with start_dtmf_generate when i use opus codec and SIP INFO dtmf. Caller ( opus/dtmf ) ------------------------ Freeswitch ----------------------------- Calleee ( ulaw/inband) Caller is using jssip webrtc and dtmf is in INFO. For inband dtmf generation i am using start_dtmf_generate in caller channel. The setup is working when i use ulaw or ilbc or alaw codec. When i use webrtc with OPUS codec i am seeing the inband dtmf generation is not working. Webrtc with ulaw codec and dtmf INFO is working fine. Version : FreeSWITCH Version 1.6.17~64bit ( 64bit) I am attaching the opus.conf.xml for the reference. Any idea, why start_dtmf_generate is not working with opus codec ?. Do i need to set any setting for opus ?. Regards
