How Much Bandwidth Do I Need for VOIP? - Phone.com
https://www.phone.com/much-bandwidth-need-voip/
Phone.com uses codecs that require approximately 100 kilobits per second (kbps) traveling up from your phone line and down to your phone line per second for each call. So if you have three people, all on calls at the same time, the minimum requirement is 300 kbps up …

of the spectrum, the telephone network carries frequencies no lower than 220Hz, and most commonly only as far down as 280 or 300 Hz. In contrast to this telephone performance, we find FM radio and television spanning 30Hz to 15 kHz, CD audio covering 20 Hz to 20 kHz, professional and audiophile audio 20 Hz
Bandwidth: Important factor for cloud telephony | NFON ...
https://www.nfon.com/en/get-started/cloud-telephony/lexicon/knowledge-base-detail/bandwidth/
The bandwidth of an analogue telephone is located between the lower limit frequency of 300 Hz and the upper limit frequency of 3,400 hertz (a bandwidth of 3.1 kilohertz), which is high enough quality to transmit a voice that can be understood. However, high-quality HD telephony uses a …
What is the bandwidth of audio? - Quora
https://www.quora.com/What-is-the-bandwidth-of-audio
Audio bandwidth is normally described as a frequency response. The range can be anywhere from 25 Hz to past 20 kHz, Which is the average normal hearing range of the human ear, stated as 20 Hz to 20 kHz. Frequency response also needs to be expressed in the range of flatness.
What Are VoIP Codecs? [Bandwidth & Comparisons] | G12 ...
https://www.g12com.com/voip-codecs/
Audio is encoded in a frame, and each frame contains about ten milliseconds of audio with about 80 samples. The single direction bitrate for this non-HD codec is 8kbit/s. With a higher compression rate, you can make more network calls at one time. However, not every VoIP can support those G.729 codecs.
sampling - Why is telephone audio sampled at 8 kHz ...
https://dsp.stackexchange.com/questions/22107/why-is-telephone-audio-sampled-at-8-khz
The analogue telephone system had a brick wall filter at 3.9 KHz. This passed all necessary info for intelligible speech and allowed bandwidth packing. Many people have been brainwashed in their thinking about necessary bandwidths. Bandwidths of 20-20,000 Hz are great for music, but completely unnecessary to reproduce human speech.

A telephone line has a bandwidth of almost 2400 Hz for data transmission. The total bandwidth required for AM can be determined from the bandwidth of the audio signal: BWt = 2 x BWm. The bandwidth of a signal depends on the amount of information contained in it and the quality of it.
Wideband audio - Wikipedia
https://en.wikipedia.org/wiki/Wideband_audio
The range of the human voice extends from 100 Hz to 17 kHz but traditional, voiceband or narrowband telephone calls limit audio frequencies to the range of 300 Hz to 3.4 kHz. Wideband audio relaxes the bandwidth limitation and transmits in the audio frequency range of 50 Hz to 7 …
