Hello, I am trialling the new mod_verto endpoint and so far it's been fantastic, definitely a great addition! I am trying to figure out what I am doing wrong in terms of codec settingss as I can only get it working with opus, PCMU will simply throw INCOMPATIBLE_DESTINATION if the channel is answered. On the very same system I don't have any issues getting PCMU over webRTC by using sofia's own WSS binding. Below are my codec string settings for verto (dropping opus will result in failure): <param name="outbound-codec-string" value="opus,PCMU,PCMA"/> <param name="inbound-codec-string" value="opus,PCMU,PCMA"/> Thank you! -- Best Regards, Ciprian Dosoftei The information transmitted is intended only for the addressee and may contain privileged and/or confidential material.
