What are the ongoing costs associated with using VoIP?
Once you have all the equipment, you will be able to make free calls (the only cost is that of having your Internet connection) to other VoIP users using a SIP service provider. A SIP service provider acts as a proxy between you and the person you want to call. Once the call is established, the data is sent between you and the person you called, not through the SIP provider. Many SIP providers offer the ability to call VoIP users who have registered with a different SIP provider. Some SIP providers make money through advertising on their website, and by offering customers premium packages which give you the option of making calls from your computer, to normal telephone lines – the prices of which are generally cheaper than traditional telephone companies, even for STD calls in Australia!
