Hello, we are using a SIP intercom, which has an open speaker and microphone. On the other side, we run a PJSUA application. Now we notice our sound gets distorted rather quickly. Both sides have AEC enabled, I see the AEC in PJSIP created in the logs. Is there any way, to tweak the AEC? How can I configure it and can it be done real time? Next is, we would like to add video. What do I need to do, to make PJSUA negotiate video media and where do I get the port and stream values when that is done? Thanks in advance! Stefan Hobbel
