Internet Telephony FAQ
What is Internet Telephony?
Internet Telephony, also known as Voice over Internet Protocol (VoIP), is a technology that allows users to make voice and video calls using a broadband internet connection instead of a traditional phone line. This technology converts voice signals into digital packets and transmits them over the internet, enabling users to communicate with others worldwide at a lower cost.
How does Internet Telephony work?
Internet Telephony uses a combination of hardware and software to convert analog voice signals into digital data packets, which are then transmitted over the internet. This process typically involves an IP phone, a softphone, or an analog telephone adapter (ATA) connected to a user’s computer or internet-enabled device. The data packets are sent to their destination, where they are reassembled and converted back into an audible voice signal for the recipient.
What are the benefits of using Internet Telephony?
Some benefits of using Internet Telephony include:
- Reduced costs: VoIP services typically cost less than traditional phone services, especially for long-distance and international calls.
- Portability: Users can make and receive calls from any location with an internet connection, providing greater flexibility for businesses and remote workers.
- Advanced features: Internet Telephony services typically offer a range of additional features like call forwarding, voicemail, video calling, and conference calls.
- Scalability: VoIP systems are easily scalable as businesses grow and require more extensions or lines.
What are some limitations of Internet Telephony?
Some limitations of Internet Telephony include:
- Internet dependency: VoIP systems rely on a stable internet connection to work effectively. Poor connectivity or internet outages can cause call disruptions or loss of service.
- Latency and call quality: Call quality on VoIP systems may vary, depending on the speed, stability, and bandwidth of the internet connection.
- Emergency services: Some VoIP services may have limited or no access to emergency services like 911.
- Power outages: In the case of a power outage, traditional phone lines generally continue to work, while internet-based telephony systems may lose functionality unless the user has a backup power source.
Can I keep my existing phone number if I switch to Internet Telephony?
Yes, most Internet Telephony providers offer a process called ‘number porting’, which allows you to transfer your existing phone number to the VoIP service. The process may take some time, and a temporary phone number may be provided for you to use during the transfer. It’s important to check with your chosen VoIP provider if they support number porting before making the switch.
