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.
