like a desktop PC is connected to the internet by a network cable a Hosted Internet
PBX similarly works in the same manner. Because your PC is connected to a
router all you have to do is simply press a button and your accessibility to the
internet is granted. So long as your service is up and running you will be able
to surf, send email, conduct online video conferences, and just about anything
else you might need or want to do on the internet.
in concept your IP phone is designed like a mini-computer to act as a fully
functional business telephone. The IP phone plugs into your internet router
using a regular network cable and once turned on can make calls, forward calls,
hold calls, transfer calls, check voice mail, and perform all the functional
tasks you expect out of a business phone. As long as the IP phone has internet
connection it will be fully functioning.
This allows an IP phone to work without geographical boundaries, enabling it to be taken anywhere in the world that has an internet connection.
Hosted Internet PBX service does not consume any notable bandwidth until you make an external phone call. Usage includes checking voice mail and dialing internal extensions within different networks.
At the time you receive or make an external phone call the bandwidth usage will be approximately 90kbps (kilobits per second).
If you have 2 external calls running at the same time the bandwidth consumed will be 180kbps until either one of the calls hangs up, at which point the consumption of bandwidth drops down.
This means you will take the maximum amount of external calls that your company receives at the same time, and multiply by 90kbps.
