Hi, I am creating a conference bridge and adding 3 call media ports to the conference Slots got created as 1,2,3 respectively for the calls. Now to talk between all three i am using api "pjmedia_conf_connect_port()" Since this API is unidirectional ,i am connecting slots like 1 to 2 2 to 1 3 to 1 3 to 2 2 to 3 1 to 3 using the above API, but if i do this then i am getting echo. Please advise what i am doing is correct or not and how to avoid this echo All i am trying to do is to talk between all 3 people using PJSIP conference without any echo. Thanks & Regards, R.D.Mano
