Asterisk Syntax

[qwerty76]

Hi, there are some providers ( giving phone numbers ), which allows you to register their system to an existing VoIP provider ( = ipkall.com )

ON the main menu, I've got
SIP Phone : 12345678
SIP proxy : sip.domain.com

I personally, would prefer to attached not to an existing provider, but to my asterisk server

- Any idea how I should configure the server ?

ex.
[ipkall]
type=peer
host=ipkall.com
....

NB: Do you think that IPKALL register as : 12345678@sip.domain.com ?
As well, I am not sure about the config on Asterisk for this syntax

Thanks
