[SIPForum-discussion] Billing system for IP calls

[Mattias Olsson]

Hi,

I now this in not the correct forum but I have to ask anyway. With what
kind of charge system can a company who sales IP telephony bill their
custemers for calls and how can the company handle the traffic? With
calls I meen calls done from a connected WIFI telephone to a cellar
phone or a PSTN connected phone.

Best regards
