Hello Everyone, I have configured my NAT like this: cfg.stun_srv_cnt = 4; cfg.stun_srv[0] = pj_str("stun1.l.google.com:19302"); cfg.stun_srv[1] = pj_str("stun2.l.google.com:19302"); cfg.stun_srv[2] = pj_str("stun3.l.google.com:19302"); cfg.stun_srv[3] = pj_str("stun4.l.google.com:19302"); cfg.stun_map_use_stun2 = PJ_TRUE; media_cfg.enable_ice = 1; It works fine with two PJSIP clients but when using with a client that do not have NAT (same LAN) or with termination there is no audio. Please help... Thanks, Dan -------------- next part -------------- An HTML attachment was scrubbed...
