You might already know that the reason is because a cell phone doesn’t transmit all of the sounds that the human voice creates. Specifically, cell phones don’t transmit very low-frequency sounds (below about 300 Hz) or high-frequency sounds (above about 3,400 Hz). The voice can and typically does make sounds at very high frequencies in the “treble” audio range (from about …

It depends entirely on the phone, they will all use different microphones/circuits. Generally, an audio mic will be within a range of 20Hz - 20kHz. Many cheaper mics ( or intended for voice only) will have a lower cutoff frequency of 15kHz or less.

400 Hz in frequency (audible tone) its output is connected to electrodes 1 and 2 in the audio plug of the first phone through a 15 kΩ resistor as explained earlier. In the second phone a 400 Hz tone must be heard. Then, a frequency sweep is made -keeping the 100 mV amplitude in all the frequencies—from 50 Hz up to a frequency which the listener

The frequency response of telephone and communication equipment is usually in the range of 300 to 3000Hz. It's a rule of thumb but may vary with specialized equipment. A 7 Hz signal is difficult to reproduce with small speakers and conventional audio equipment. I've hooked up audio signal generators to amps and speakers before and watched the
