Hi can some one help me . I am using kamailio 4.1.3 and having one way
audio issue.
Scenario is
Pjsip 2.0 based UA (private IP)------->Router(publicIP)--------> Kamailio
(with RTP proxy)-----------> Third Party_Sip Server ------>PSTN
UA is registering fine with sip server but when i make a call they can
hear but i can not hear the other party .
What i found is in SDP first c=IN is private ip of UA and second c=IN is
public ip of UA i dont know if this is the cause
When I trace the call on sip server , sip server is sending RTP to UA
private ip so
it is not reaching kamailio back to forward to UA .
I am attaching the kamailio configuration file as well as SIP/SDP trace
user agent private ip : 192.168.1.4
User agent public ip : 61.61.61.61
Kamailio IP : 81.81.81.81
Sip Server IP: 71.71.71.71
(* ip addresses are not actual ips)
Please reply with detailed instructions to fix this isue
