I could register using credentials shared by Denis from an Amazon EC2 instance (which is on public IP) but not from my local home machine which has a dynamic IP (behind the broadband provider's NAT).
The scenario where it worked went like this:
FS -> IPTEL SIP Request: REGISTER sip:sip.iptel.org;transport=udp
IPTEL -> FS SIP Status: 401 Unauthorized (0 bindings)
FS -> IPTEL SIP Request: REGISTER sip:sip.iptel.org;transport=udp
IPTEL -> FS SIP Status: 200 OK (1 bindings)

@Brian, you better take some rest.
