When reading conference bridge on pjsip.org/pjmedia/docs, I see these 2 port. What are they, are they the same ? When running pjsua_app, I use "cl" command to list port in conference bridge, I see pjsua_var.mconf->master_port->info->name = "Wave mapper" pjsua_var.mconf->ports[0]->name = "Wave mapper" pjsua_var.mconf->ports[1]->name = "ringback" pjsua_var.mconf->ports[2]->name = "ring" pjsua_var.mconf->ports[3]->name = "sip:voip1 at freesipserver.com" And it says ports[0] is transmitting to port[3], and port[3] is transmitting to ports[0] Any answer is highly appreciated, thanks in advance. -- Khoa Pham HCMC University of Science Faculty of Information Technology -------------- next part -------------- An HTML attachment was scrubbed...
