[pjsip] Authentication Problem with Proxy

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
--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
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)
(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.
