[Freeswitch-users] [OT] How do I port my home phone number to a SIP address?

Hi, guys, This might be a little off topic, but I think many experts here may know this already. :) I have a VOIP server set up and running. Now I start to think how to port my home phone number to this server. Basically what I want is if someone calls my home phone number I like to see a SIP connection to my own VOIP server. Currently I'm using bbtalk as my home phone service. I'm pretty much sure they don't provide this service. Who would be able to provide this service? I live in USA. Thanks in advance. Jun
