Hi,
our VOIP works perfectly also with a Modem connection or ISDN ( of course we have special telephones in this case) because of the high compression of the voice.
In my opinion, of course the most convenioent is using it with a DSL or more and a flat fee connection.
In this way the cost of the telephone call is zero and one can talk as long as he wants also in an intercontinental call.
The quality is amazing, I would like to show it, we will demonstrate it in Geneva in October at the Telecom show.
And the price of the hardware is nothing compared to the ones of Cisco and Nortel, which do not even work.
A telephone call consumes around 20 K ( some say 6, 8 k, but that is with a software and the quality is terrible) considering that with a slow ADSL you have 256/128 you can see that the amount of bandwidth is more than enough.
We do not have delays or echoes which are the most disturbing features in a VOIP.
We also can have a 1.000.000 bit encription which is practically unhackable.
I can assure you, it is just a matter of time, but the Telecoms can say good bye to all their sucking and cheating ( at least that is the behaviour of the Europeans).
We will finally be able to call when and how and how long….
