Cách điện thoại IP Điện thoại có dây hoạt động

Điện thoại IP Điện thoại có dây is a different, clearer way of transmitting telephony voice. It works by sending your voice data over the internet. More specifically, it converts sound into digital communications, which are then sent in “packets” using Internet Protocol (IP). This is different from traditional telephony transmissions that are handled on the Public Switched Telephone Network (PSTN). PSTN is also known as POTS, which stands for “Plain Old Telephone Service”. It is an old-fashioned landline telephone system that uses copper wires to transmit analog voice data.
What are the benefits of IP telephony for businesses?
There are many benefits to using a VoIP small business phone system.
It’s cheaper than the traditional phone system. That’s because traditional phone companies have higher costs in overhead, industry regulations, and expensive infrastructure maintenance, much of which is passed on to customers to pay.

Since calls are transmitted over the Internet, the cost of long-distance and international calls is greatly reduced.

Comparison of IP Phones and Ordinary Phone
Compared with ordinary PSTN phones, IP phones have the following advantages:
· Save bandwidth. The bandwidth consumed by the circuit switching telephone is 64kbit/s, while the IP telephone only needs 6-8kbit/s (sometimes even lower than 2.4kbit/s), thus saving the bandwidth and reducing the cost.
·Low cost of calls. The reduction in cost has led to a decrease in call costs, especially for long-distance communications.
·Intelligence can be easily integrated. The IP telephone network inherits the intelligent modules of the computer network and can flexibly control signaling and connections, which is beneficial to the development of various proliferating services.
· Open architecture. The protocol system of IP telephony is open, which is conducive to the standardization of products of various manufacturers and the connection between them.
· Integration of multimedia services. The IP telephone network supports the transmission of voice, data, and images at the same time, laying a foundation for the comprehensive provision of multimedia services in the future.​​
However, it is also obvious that the service quality of IP telephony is inferior to that of ordinary PSTN telephony.
