SIP server, VOIP

Hi everyone,

What I want is to have SIP address the same as my email – sip:julian@hostname.com. This would ring my softphone (Ekiga) whenever I'm online, or redirect to my cell if I'm not (via the SIP > PSTN service at www.callwithus.com). Does anyone have experience doing something like this?

There are a whole bunch of different SIP proxies/servers out there, but a lot of them seem to do a lot more than I need. Any suggestions?

Yours

Julian
