In a way it's kind of like an email address.
You know how in my post on HG forums, I said in some cases we can route the call completely over the internet and avoid paying the traditional telcos for the call going on their network? That's basically how we do it...convert the number to a SIP address.
Say you have a friend with software that lets them call SIP address (it's the gold standard protocol for VoIP). If they have your SIP address, they could call you directly using it instead of your phone number.
So if they were in Japan and they wanted to call your US VOIPo number, they would likely pay their phone company international charges to call you since it's in the US. If they have your SIP address and use something to call it directly, the call is directly between you two bypassing the entire phone network and associated fees![]()
