Scratching the surface of VoIP

July 3, 2006

My previous post I mentioned VoIP, since this blog is about explanation….

VoIP is a way of converting and carrying your voice over the Internet, usually it is then converted to your conventional land line to your
destination. Some of the jargon words you might encounter are PTSN,TERMINATION, SIP. Lets take one of these words at a time
then carry on with the explanation since we will use some of these in it.

  • Termination is where your Internet phone call gets converted to a conventional line then to its final destination. Lets say
    I want to make a call a from a city in Michigan to say London in the UK using VoIP but the destination phone is the old
    phone network. I pick my VoIP phone up, dial the number, it then goes over the Internet to a termination point in London
    where it gets converted from VoIP to the old phone system, that termination point then links my VoIP call to the old phone
    network. The caller on the other end does not know any different, to them I could be using the regular system, since I am
    using VoIP I am saving a considerable amount of money since my call is over the Internet.

  • PTSN , I really should of explained this first, would of saved me some typing in the previous explanation, oh well:) This is
    your old phone system technology (Public Telephone Switched Network), its what is used now, unless you use VoIP then you have
    it in your home.

  • SIP, Stands for (Session initiation Protocol), its one of the protocols that VoIP uses to communicate with, you will hear “I bought a
    SIP phone..” A phone you can plug into your network and call away with, as long as you have a provider of course. Some VoIP providers
    offer ATA devices (Analogue Telephone Adapter) which makes your regular phone into a VoIP phone. Its just a black box than you plug
    your network in and your regular phone into, some of these boxes act like regular routers also.

There is not many perquisites with this technology, but one, you need a broadband connection, DSL or Cable, since a Dial-up connection
just doesn’t have the bandwidth to allow a two-way conversation, even if you have a Web accelerator this will still not help since it deals
with the web browsing..

Local number porting is a way of changing the destination of your local number, instead of it going to your regular provider it will go to your
Now we have the outline on how it works, lets pretend for a sec here we decided to get rid of our normal phone provider and opt to go VoIP.

Firstly you choose a provider, since Vonage maybe the best way to go since its a plug and play affair.. A few things that you need to make sure
with your provider of choice is if they can port your local number, since you are getting rid of your old system you still may want to keep your
old number. This is perfectly possible, plus you can get a new number, infact many numbers, even a 1-800 number.

VoIP provider, this can take up to 10 days, it really depends on your provider. In the meantime some providers will provide you with
a temporary number for your area, a DID this is called, you can have as many DID`s pointing to you as you wish.

I think I have covered the foundation, Later I`ll post how you can do some real swank things with VoIP and your own home phone system, my
goal with this blog is to answer any question or elaborate on any posts so please go ahead and let me know.

Be safe..
