Why is UDP/IP used to transmit and receive packetized voice signals over and IP network and not TCP/IP used in VoIP?

Expert Solution

Generally TCP is called connection oriented service wheareas UDP is calle connection less service , with this defination TCP need live connection like video streaming , where as email uses UDP protocol because it does not need continues connection but whenever need to transfer mail transfer at that time only connection is being established.

Now in VoIP we have different speeds in our network connection suppose source or caller have 3G speed and calee may have 2G connection so calee will get packets late in compare to 3G caller packets so UDP protocol allows late delivery as connection less service is not guarantee for sure packet delivery.

if you have any doubt then please ask me without any hesitation in the comment section below , if you like my answer then please thumbs up for the answer , before giving thumbs down please discuss the question it may possible that we may understand the question different way and we can edit and change the answers if you argue, thanks :)
