To achieve CD quality (16bit/44.1khz stereo) need 1411.2 kbit/s bandwidth, obviously Bluetooth A2DP cannot allow (Bluetooth 2.0/2.1 + EDR The largest carrier rate is about 2.1mbit/s, minus the protocol header, interference, power dissipation factor influence , the actual maximum transfer rate is approximately 1000bit/s), so the audio data needs to be compressed. We know that the same bit rate, different encoding format compression rate is different, thus decoding the quality of the restoration i

We now have a lot of knowledge about VoIP technology, and we are almost at risk to talk about other applications and usage knowledge. In the use of VoIP technology, we will transmit voice signals in the IP network. However, there are also many technical needs to achieve long-distance IP network spanning. ◆ Session edge controller SBC) Technology Session edge cont

Too many VoIP service providers want to sell you their "full solution", from the phone number on your desk, from different sites to the WAN and public exchange Telephone Network (PSTN). However, as I have seen, Unless users and suppliers have full experience and thoroughly checked every detail, the so-called "full set of VoIP systems" will certainly make some mistakes. Enterprises that have trouble with

In the current network communication, the Email service is no longer the preferred communication method. More instant messaging and voice services are emerging on the network. Now let's talk about the technical principles of VoIP for IP phones.Basic transmission process The traditional VoIP telephone network transmits voice in a circuit exchange mode. The required transmission bandwidth is 64 kbit/s. The so

Every organization that is considering deploying a VoIP Phone System has heard the same terrible warning: "routing voice calls over the data network will expose the call content to eavesdroppers ".Although in fact, any phone call is at risk of being eavesdropped to some extent, is the VoIP call system itself at a high risk? In this article, we will explore the ins and outs of

How can I test the VoIP function with an existing PBX or key-press system? There are multiple ways to use the existing PBX system or key-press system to test the VoIP function. How to test the function depends on your purpose. If there are two sites connected with PBX connection lines, but you want to use VoIP so that you can send calls between internal network

The basic idea of the Subband encoding (Subband CODING,SBC) is to use a set of Bandpass filters (Band-pass FILTER,BPF) to divide the frequency band of the input audio signal into several successive bands, each of which is called a subband. A separate coding scheme is used to encode the audio signals in each sub-band. When transmitting on a channel, the code of each child band is composited together. At the receiving end of decoding, the code of each

1995 Israel VocalTec Company launched the Internet phone, not only is the beginning of VoIP network telephony, also opened the telecommunications IP prologue. People will not only be able to enjoy the cheaper and even completely free call and multimedia value-added services, the service content and the face of the telecommunications industry has also changed drastically.

It runs as follows: Gullible users receive an e-mail (or a phone call), are told that his credit card information is being stolen, and then let him quickly dial a phone number. This phone will have computer-made voice prompts, let him enter credit card number and other authentication information and so on.

Background information One feature of VoIP-type apps is the need to keep running in the background to be able to receive incoming calls at any time. Because of this special mechanism that the system provides to the VoIP process, we are unable to completely kill the VoIP process by killing command directly.
