Re: [SR-Users] kamailio/asterisk no call with sound if use rtpproxy/rtpengine

hih thanks for your respond, but seems you dont paid attention to my problem, with ports opened and redirected to pulbic ip with the AWS firewalling (tech support) call have sound, but and later NAT traversal with rtpproxy as i understand in simple we must have: phone/caller-->[-->rtpproxy->kamailio->asterisk->kamailio->rtpproxy -]->phone/dest then there's no sound...
