Which of the following statements are correct regarding VoLTE?

1.VoLTE stands for 'Voice over Long Term Evaluation'

2.It is a digital packet voice service delivered over IP via an LTE access network

3.It provides more efficient use of spectrum than traditional voice

4.It eliminates the need to have voice on one network and data on another

A1, 2, 3 & 4

B2, 3 & 4 only ✓ Correct

C1, 2 & 3 only

D1, 3 & 4 only

Correct answer: (B) 2, 3 & 4 only

Explanation

VoLTE stands for Voice over Long Term Evolution, delivering calls over a 4G data network instead of a separate circuit.

Statement 1 is wrong because the acronym expands to Long Term Evolution, not Long Term Evaluation.

Statement 2 is correct as it is a digital packet voice service carried over IP on an LTE access network.

Statement 3 is correct since packet voice uses radio spectrum more efficiently than older circuit switched voice.

Statement 4 is correct because voice and data travel over the same LTE network rather than two separate ones.

Older 4G handsets without VoLTE fell back to 2G or 3G networks just to place an ordinary call.
