Help debug Sip registration

[Neoscopio]

Some how I'm able to register sip phones and softphones but not as a freeswitch gateway. I've tried several combinations to no avail.

My provider instructions are:

· Endereço Registar (Host): sip.sapo.pt
· Endereço Proxy (Outbound Proxy): proxy.sip.sapo.pt
· Porta Proxy: 5070
· Username: +3513020xxxxx (*)
· Password: [de 6 a 8 carateres]
· Transporte Rede (Network Settings): UDP
· SIP URL: +3513020xxxxx (*)

I've entered this as username: +351xxx, password: xxx, proxy: proxy.sip.sapo.pt:5070 , from domain: sip.sapo.pt
Doesn't work.
I went to advanced and set transport to udp and outbound proxy as proxy.sip.sapo.pt:5070 didn't work wither.
Tried all combinations I could but also no cigar.

Can anyone help me debug this?

Here are some fs_cli logs:

I would send the above to the carrier and let them tell you what is wrong.

Yep, that has been done, they say everything is ok and nothing more, and they don't support fusionpbx. At least for sip phones they are correct. It's just that I can't figure out what sofia is doing different from sip phones or softphones (zoiper is working). Fusionpbx is in a proper server in a datacenter with public IP address. Sip and soft phones are behind nat.
