IPKall is a public switched telephone network to voice over IP call forwarding service. Users may register with the service to obtain a phone number chosen from several Washington State LATA prefixes and have all calls to that number forwarded to their Session Initiation Protocol or Inter-Asterisk eXchange uniform resource identifier, including an Asterisk server. The telephone company that provides IPKall numbers is International Telcom.
IPKall's popularity stems from the fact that it is probably the only remaining, widely accessible VoIP service offering free-of-charge PSTN numbers.
[edit] Business model
The IPKall business model appears to be based on its ability to charge termination rates for calls reaching its subscribers, estimated at about $.01/min,[1] as the service is free for end users. Direct customer support is not provided, but IPKall representatives answer some inquiries at an online forum.
