1.  iptel was doing maintenance/reconfiguring on 11 September.  I don't have an OBi registered to there but I do have iptel as a PBXes trunk and that had problems for most of the day.

2.  If you are still not registering try removing the 'sip' and just using 'iptel.org' in the server fields.

Have you tried this?

AuthUserName = myusername
URI: <blank> (or default)

If still not working, try this:
Service provider proxy server: iptel.org

(Keep everything else same as what you have)
