Answer:

3.1 Mbps

Explanation:

Voice comes in 8000 Hz frequency, so 16000 samples required each seconds.  

1 sample if of 8 bits.

16000 sample if of 128000bits.

these bits is send per second.

so bandwidth required is 128kbs for single voice.

for 24 it is 24 x 128 kbps

= 3072 kbps

= 3.1 mbps
