For each master!!!!!! In my local server on the local area network (LAN) built a opensips server (IP) and port is mapped to the network, set up after the completion of the mobile terminal (linphone) and PC (x - lite) can normal login, can also talk to each other, but the mobile end use 3 g network can't log in, can't voice calls, and then I set up on the server again RTPProxy, PC can then breathe through mobile terminal (wifi and 3 g, 4 g), but still couldn't get through PC phone end, mobile phone and mobile phone can't with each other (dial-up no response), and the server log as follows, this phenomenon is why each master, please? How to solve?
