Hello Mario,

hard to say from where the problem originates without more details. Let's begin with network dumps -- send them to us over, we will try to look at them. ("ngrep port 5060" does the job, for example).

What I noticed (which might or might not have been the case to which you are referring) is messages to sip:mko@cs.stir.ac.uk which returns "478 Unresolveable destination". The domain name "cs.stir.ac.uk" is not resolveable:

[jiri@fox log]$ nslookup cs.stir.ac.uk Non-authoritative answer: *** Can't find cs.stir.ac.uk: No answer

Hi,

I have installed SER on linux and created a few users. I can register these users from SIP phones and soft-phones and can also establish connections between them. I have also created a user on the iptel.org server.

I can ring from a client registered with my domain (cs.stir.ac.uk) the client registered with iptel.org. It works perfectly. However, ringing from the client registered with iptel.org a client registered locally doesn't work. Is this a config problem? How can I fix this?

Any help is greatly appreciated!

Best regards, Mario Kolberg
