I thought internet based phone (VoIP) calls would be free?
In theory, calls made completely through the internet have little or no cost. So, until all telecom users adopt VoIP, virtually all of your call recipients will answer through a landline or cellular phones, and such calls have to completed via a traditional phone network. Because of this, the VoIP company has to pay termination charges to the phone companies. Ultimately, you are responsible for these termination charges. Even with these charges, VoIP usage is far cheaper than traditional telecom service.
