Hi, My application requires adjustment of the volume level of audio to the sound card of multiple calls independently. One call may have a volume level of 80% and another 120% and be connected to the same sound card. pjmedia_conf_connect_port has a parameter for this, but it is not implemented yet. Are there any foreseeable difficulties in patching pjmedia_conference to support this? An alternate solution is to 'nest' conference bridges and set the master port volume of the nested conference. regards, Nishant
