Hello, I try to invite a user into a conference by loopback/255 8000 Conference 255 is the user, I invite the user via loopback as that way I can also invite external numbers. It processes the user's local dialplan correctly (as if the user was normally dialled), however it only offers L16 codec, so the Phone fails. I can see no codec negociation on the debug console. If I call the phone from another phone, then codec negociation is taking place. If I invite an external PSTN user into the conference then codecs are set correctly (L16+PCMA+PCMU etc) Is there a way to explicitely set the codec for the conference? <!--<param name="disable-transcoding" value="true"/>--> is not set is, still commented in the internal profile. In vars.conf.xml only only PCMA and PCMU are set. Best regards Peter
