监管如何通过代理服务器发送RTP数据包

[英]Reg how to send the RTP packets through the proxy server

原文 2010-11-24 14:27:47 1 1 c++/ symbian/ rtp/ pjsip

I am using the pjproject1.6 and I could send the sip packets through the sip packets to the proxy server and the rtp packets or not pass through the server. 我正在使用pjproject1.6，可以通过sip数据包将sip数据包发送到代理服务器和rtp数据包，也可以不通过服务器。 Hence the voice could not be heard on both sides. 因此，双方都无法听到声音。

I have checked in proxy server, rtp proxy is running and when proxy server sends 200 Ok, the SDP packets from PJSIP includes the IP address of the proxy server. 我已经检查了代理服务器，rtp代理正在运行，当代理服务器发送200 Ok时，来自PJSIP的SDP数据包包括代理服务器的IP地址。

Still the sound/media are not transmitted to both PJMedia client and reciever. 声音/媒体仍然不会同时传输到PJMedia客户端和接收者。 I have tested the same scenario with the yate client, audio/media is heard both on the sender and reciever. 我已经使用yate客户端测试了相同的方案，发送者和接收者都听到了音频/媒体。

Is there any other config/code change that should taken care from PJSIP? 是否还有其他配置/代码更改应通过PJSIP进行处理？
