SIP to SIP calls

Hi,

Could anyone tell me if it is possible to make SIP to SIP calls with Asterisk?

Is it possible to dial something like this: sip:@somedomain.com

How would asterisk need to be configured to make and receive such calls (I believe you do not need a provider since the calls are all over the internet)

Thanks,
Dario

Yes, Asterisk may do this. I recommend having a look here:
