How VoIP differs from your "normal" phone line....

In the last blog I mentioned VoIP uses the internet to make / receive telephone calls. This has many interesting ramifications that make VoIP useful for business continuity.

It is becoming well known that making calls over the internet can be cheaper and indeed free if made from one PC to another. This is because the call doesn't need to route through a public telephony provider's network as with regular telephony.

However, if a call is routed to the a recipient who uses regular telephony, the call will have to "break out" of VoIP into the public telephony network.

Conversely, if a call is originated from the public network and destined to a VoIP user, the call needs to "break in" to the VoIP network.

Confused? It's like starting a journey by train and continuing it by road. Start on VoIP, end on the public network and visa versa.

Now here's the big difference - a user can login to a VoIP account where ever they have a suitable internet connection. Calls will be delivered to where they are logged in.
