VoIP information: phone service and inter-connection with the PSTN solved

The blue area in the figure represents the area surrounding the VSAT terminal.  It might be a small community, commercial area,  large office, call centre or internet café. A number of analogue phones or VoIP phones are connected via Quintum equipment to the VSAT modem. Satellite dish "Site A" in the figure is a representation of the VSAT terminal, while "Site B" represents the large Hub Teleport site where the calls may go direct to other VoIP phones connected to the internet or to conventional PSTN telephones anywhere in the world.

Our clients install VSAT hubs in order to have a direct connection to the US Internet. With this Internet connection they have the ability to install analog telephone lines connected to a VoIP gateway.

If the client is a sub office of a large company, VoIP provides them with free calls to their head office. Depending upon their need they may have from one to 30 lines in use at any one time. We call this on-net traffic termination.

In most cases our clients wish place calls to people who do not have similar VoIP systems. We can handle this process as well!

We use a carrier grade telephone switch that has the ability to convert the VoIP signal back into normal telephone calls and place the call to the called party, anywhere in the world. The call to our US switch is free but we do charge for the second leg of the call, from our switch to its final destination.

Consider the economies of someone in Botswana, Africa calling by VoIP to a bank in the States or Europe. The first leg of the call comes via VoIP through our satellite to our switch for no charge. The second leg of the call to Europe or the USA will incur a charge is 5 to 10 cents a minute. You could say that the total call from Botswana to the US is only 5 to 10 cents a minute. By comparison their local telecom is likely to charge the Botswana client one dollar a minute.

Quintum VoIP equipment

The largest family of VoIP routers is the Cisco 5300 and 5350 series. The 5300 can be configured for 4 T1 or 4 E1 digital lines and are perfect for high volume digital environments, such as telephone companies.

The majority of our clients operate Cyber Café’s with 8 to 16 analog telephone connected to a PABX. In this case the Cisco product is unsuitable, instead we recommend the Quintum Tenor A800 VoIP Gateway. Quintum will connect directly to analog lines and the units are reliable and easy to configure.

If the bandwidth is sized correctly the voice quality is excellent using either Cisco or Quintum products.

An independent testing company evaluated the Quintum product range and produced a favorable report.  Contact us to discuss your VoIP needs.
