Here is "official" config expamle for esterisk:

Hi.
There is a manual maybe you can refer to: www.openvox.cn/pub/manuals/Release/Engli..._Asterisk_Server.pdf

I saw this manual before but it didn't help me
Just look at .../asterisk.tgz please

Hi.
what do you mean "make it from the web-GUI without config-files editing"? For out geteway, you can edit your sip trunk and your routing rules in web-GUI, you can find them in the manual.

I mean: configure connection to external SIP without "ADVANCED/Asterisk File Editor" submenu
Or... I shuold edit line "register=>..." manually anyway. Right?

you can set Registration in SIP - SIP Endpoints, if you want to use a sip phone or pbx to register to your gateway, you can set it as "Endpoint registers with this gateway", if you want your gateway register to anther pbx, you can set it as "This gateway registers with the endpoint", or if you want to config it as ip to ip, you can set it as none.
