What is IP telephony?
IP telephony is a technology that allows integrating on a single network both voice and data communications. It uses internet protocol to send voice information.
IP telephony operators are interconnected to public telephony, the place all operators are connected to each other and that’s what allows you to call from your phone to any other company by dialing the appropriate number.
Businesses shouldn’t continue to pay large amounts of money for their phone lines while technology improves and decreases the cost for them. Moving towards IP technology can bring your monthly phone bill down by half.
The main advantages are:
• Simplification of the communications infrastructure within the company.
• Interconnecting and integration between different branch offices and their employees.
• Centralized management via a unified system.
• Free internal calls.
• Integrated numbering plan and communication lines optimization.
• Access to advanced features (voice mail, IVR, ACD, CTI).
• Lower maintenance, management and administration costs.
• National coverage.
• Saving in infrastructure and energy, by integrating voice and data in one service.
How IP Telephony works
In order to send voice over internet, IP telephony transforms the voice signal, which is analog by default, into data packages that can be sent via internet. In the same way, it decompresses these data packages so that voice might be heard by the person on the phone.
Compression and decompression are also done when a call changes from one transmission media to another (internet to cable), connecting operators on different systems through a commutator.
