[Asterisk-Users] direct ip-to-ip call

[CuPoTKa]

Hello!

I'm searching for a way to call ATA (IAX or SIP) that is not registered 
with any server or proxy.

Is it possible to make such a call from a softphone to an ATA just with 
IP? Something like (sip:// or iax://)1111 at 210.12.34.45 (where 
210.12.34.45 is ATA's public ip)?


Regards,
CuPoTKa.
