My ISP Tiscali (now together with the other dutch provider Telfort) have set up a new VoIP solution, called DigiTalk. They previously used SIPExpress. Now, my asterisk box would not register anymore. Well, that was partly my fault, because I put up records in my hosts file, staticly addressing their SIP Proxy. So now, when I called, I got a recording saying I should reboot my modem, bla bla.

After an evening of trial-and-error, and searching on the net, I have a working configuration again. My sip.conf: (my asterisk box is not behind NAT, and this is not my real phone number. My hosts file has no more related records anymore)
