Skypejournal mentions a hack to create a SIP address that will ring to your Skype name using the Net2Max.com service. It’s a rather tedious process, but there is a nice step-by-step write-up to get things set up.
I tried it and it does work. As the guide suggests, it might take some time for the stuff at Net2Max.com to get provisioned, but I went through all the steps (well done by the way), and at first it didn’t work, but I waited a few hours, and then it did work! By placing a call using PhoneGnome to the SIP address sip:MYNUMBER@sip.syd.net2max.com presto! I get an incoming call on my Skype client (from an odd username).
I wonder how many concurrent calls this system can handle? One would assume they’re using some kind of hack into multiple instances of Skype running on PC’s somewhere in their datacanter to bride the calls from SIP to Skype. I’d be very curious to know exactly what they’ve got there. Does anyone know?
Overall though, it is very cool. The steps are somewhat involved, but the above write-up is good, and you only have to set it up once. If you have a way to dial to a SIP address, you can skip the whole discussion of dialing a SIPbroker access number and such. Instead, simply place a SIP call directly to your Skype account at sip:NUMBER@sip.syd.net2max.com from your SIP client or SIP compatible service.
So when will Skype officially support SIPin and SIPOut? As Phoneboy notes, they say nobody wants it, but services like this suggest otherwise.
