Hello,ycaner! 

Now I use a real IMS user data to register this user(for example
18616278715) to China Unicom's IMS through kamailio. 

I can register successsfully, and can make call using this number, the
callee can pick up phone. However 
neither party can hear counter part. 

So, this should be rtp problem. And I captured a .pcap file on port 5060
like below. In this, I see in SDP information 
it says 192.168.199.124, it's a  private address. So maybe the callee can't
setup a circuit to this ip, and thus no media was transfered? 

Should I uncomment RTPPROXY_ADDRESS, as in my pcscf.cfg there are two lines.
If I should do this, what ip and port should I use to replace
"udp:10.1.2.186:22222 udp:10.1.27.217:22222" ?

# IP-Adress(es) of the RTP-Proxy 
##!define RTPPROXY_ADDRESS "udp:10.1.2.186:22222 udp:10.1.27.217:22222" 
##!define RTPPROXY_ADDRESS "udp:10.1.2.186:22222" 

This is the .pcap file captured on port 5060.
