Hej, I face a little troublesome problem using PJSUA. I have just a little test LAN, including 2 hosts using PJSUA, one server running a SIP proxy including the registerar. The server as registrar as well as as Proxy requires authentication. Now, if I make a call from one client to the other, having specified the registrar and the proxy. The config is like this: --id sip:first at domain.com --registrar:123.100.200.300:5060 --proxy:123.100.200.300:5060;lr --realm * --user first --pword xyz --add-buddy sip:second at domain.com (2nd config on the 2nd host vice versa, of course) So, registering works fine. If I look in Wireshark at the exchanged messages, everything works, the clients first send the INVITE message, a Status:407 "Proxy Authentication Required" response comes back with the valid credentials, they are filled into the new INVITE message and the registration is successfully completed. So, that's the setup. Now I come to the point where I am going to establish a call between the both UA's. The proxy gets the INVITE message for the call, telling me (as before, see above) Status:407 "Proxy Authentication Required". So far I get it. The next (new) INVITE message is created, inclunding now the credentials, and send by the calling UA. It reaches the server, as I see in Wireshark, but no more action can be observed. My Wireshark messages (as the Debug output in PJSUA does as well) looks like: (server==SVR/first host==FIR/second host==SND) Source Desti. Message 1. FIR SRV Request: INVITE sip:second at domain.com, with session description 2. SRV FIR Status: 100 Trying 3. SRV FIR Status: 407 "Proxy Authentication Required" 4. FIR SRV Request: ACK sip:second at domain.com 5. FIR SRV Request: INVITE sip:second at domain.com, with session description 6. SRV FIR Status: 100 Trying 7. SRV FIR Status: 408 "Request timeout" 8. FIR SRV Request: ACK sip:second at domain.com That is the whole message exchange. No INVITE ever reaches the second host. I tried several approaches, also entering the realm by hand, not using the wildcard, using IP addresses in the sip:URI. Absolutely no success. I checked, if the gained credentials are exactly the same, and they match. The network setup works just fine, when there is now authentication in the proxy. I really wonder why? I am pretty new to PJSIP, so I might lack the important part what I am doing wrong. Please if you have an idea, give me a hint, every help is appreciated. Greets, Markus
