<div dir="ltr">Hi can some one help me . I am using kamailio 4.1.3 and having one way audio issue.<div><br></div><div>Scenario is </div><div><br></div><div>Pjsip 2.0 based UA (private IP)------->Router(publicIP)--------> Kamailio (with RTP proxy)-----------> Third Party_Sip Server ------>PSTN</div>
<div><br></div><div>UA is registering fine with sip server but when i make a call they can hear but i can not hear the other party .</div><div><br></div><div>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</div>
<div><br></div><div>When I trace the call on sip server , sip server is sending RTP to UA private ip so </div><div><br></div><div>it is not reaching kamailio back to forward to UA .</div><div><br></div><div>I am attaching the kamailio configuration file as well as SIP/SDP trace</div>
<div><br></div><div><br></div><div>user agent private ip : 192.168.1.4</div><div>User agent public ip : 61.61.61.61</div><div>Kamailio IP : 81.81.81.81</div><div>Sip Server IP: 71.71.71.71</div><div><br></div><div>(* ip addresses are not actual ips)</div>
