Voice over Internet Protocol (VoIP) utilizes the Internet’s ability to packet-switch, helping provide efficient business phone service.
What are the benefits of VoIP phone systems?
- Packet Switching allows numerous telephone calls to occupy the same amount of space as one circuit-switch network.
- VoIP only sends “noise” data, eliminating dead space and unused airtime. For example, 10 minutes of conversation transmission data, can really occupy only 3.5 minutes of actual usage. Utilizing business VoIP allows several additional calls to conveniently fit into that same amount of time.
How does VoIP work?
- When a receiver is picked up, it sends a signal to the ATA.
- The ATA then receives this signal and forwards a dial tone, allowing the caller to confirm he/she has an Internet connection.
- The caller then dials the number of the receiving party. The tone is immediately converted by the ATA into digital data, which is then temporarily stored.
- The phone number data is then sent via a request form to the VoIP’s call processor. This process confirms the information is being presented in a valid, readable format.
- The call processor rapidly determines where to map the entered telephone number. When using VoIP technology, translating the number directly into an IP address completes mapping. This then connects both devices, resulting in a soft switch connection. Then a signal is sent to the receiver’s ATA, resulting in the phone ringing.
- Once the receiver answers the phone, a connection is established between both computers. Each system understands and deciphers the data packets that are rapidly being sent from each computer. Because each system is equipped with VoIP, the computers expect these packets of information, essentially processing them much like a web page or an email. The systems then implement or establish two channels, one for each direction of communication.
- During the conversation, the systems transmit packets rapidly back and forth to one another. These data packets are received and immediately converted into analog auditory signals. The ATA helps keep the circuit open and initiates forwarding information packets from the IP host to the receiver.
- Once the call is complete and both parties hang up, the circuit is closed between the ATA and the telephone.
- The ATA then sends a signal directly to the soft switch, terminating the session.
Many businesses find themselves switching to VoIP hosted technology because they understand the basics of technology. By taking their business one step further and migrating to advanced VoIP technology, telephone networks have the ability to communicate the same way that computers do with one another.
Additionally, many companies that have switched to VoIP business services have saved thousands of dollars on traditional telecommunication expenses and greatly boosted employee productivity.
