INTRODUCTION:
Mobile phones use GSM and VOIP uses IP network. So instead of the phone breaking up your voice and sending it over the air, VOIP breaks it up and sends it over the internet.
So if you can use a mobile you can use VOIP.. As for call quality.. Generally similar to a mobile phone call. Like mobiles though it can vary.
TERMS:
ATA – Analog Telephone Adaptors, box that plugs into your network on one side and a phone on the other.
Softphone – Similar concept to the ATA but runs as software on your computer.
VSP – Voice Service Provider, the company that provides the VOIP facility.
PSTN – Public Switched Telephone Network (ie a normal phone line)
Broadband – Highspeed internet, much faster than using the older dial up modems.
Router – The box most people have which connects them to broadband internet.
Skype – Well known VSP great for free computer to computer calls, but call rates to land lines are not so competitive. Also doesn’t use standard codecs so cannot use standard ATA’s. Codec – Software for the conversion of analogue (voice) to digital. Most commonly used in Australia
