I've tried two different numbers and they both fail. I can make regular mobile calls but not VoIP calls via my SIP softphone (media5fone). What do you mean if my phone is registered?

A sip phone register to SIP server with a username and password - that is what I mean with registered.

Note that iptel.org does not allow you to call to pstn, unless you have your own pstn gateway configured. You can do voip calls for free.
