Well, you are right. Looks like the problem is not with authorization
but in the line

  Contact: <sip:gw+1.2.3.4 at 5.6.7.8:5080;transport=udp>

that the gateway would like to see as

  Contact: <sip:username at 1.2.3.4>

I've found (almost undocumented) parameter extension-in-contact, but
it still gives

  Contact: <sip:username at 5.6.7.8:5080;transport=udp>

(1.2.3.4 is my IP address, 5.6.7.8 is gateway's one). Any idea how to
overcome this?
