[asterisk-users] Asterisk unable to register to tnet.it

[Giorgio Incantalupo]

Hi,
I cannot make my Asterisk register to tnet.it, an italian SIP provider.
I tried many register string formats and tried to set realm and 
outboundproxy (sip.tnet.it) too but without any result.
Still I cannot register (but for example messagenet works fine).
Is there anybody who tried this provider and successfully registered to it?

Thank you.

Giorgio.
