What's the difference between VoIP and fixed line? Please answer it.

There are the following differences between VoIP and fixed telephone:

1. Physical properties: VoIP calls the other party's fixed telephone and mobile phone directly through the Internet, including domestic and international long-distance calls, while fixed telephone calls are fixed in a certain location and are mostly used in enterprises.

2. Cost: The cost of VoIP is 65,438+00% to 20% of that of traditional telephone, while the fixed telephone generates different costs according to the time and place of the call.

3. Usage: Internet phone can download the software from the computer, buy the Internet phone card, and then communicate with the other party (fixed phone or mobile phone) through headphones. The fixed phone uses the microphone in the phone to modulate the current and voltage on the telephone line through the vibration of sound, that is, the sound is converted into a voltage signal, which is transmitted to the other end of the phone through the telephone line, and then the voltage signal is converted into a sound signal through the microphone.

Generally speaking, VoIP has higher portability and lower cost, while fixed telephone has higher stability and adaptability.
