Frequently Asked Questions
Why is voice calling cheaper than video calling?
Voice consumes far less bandwidth—about 1/10th of what video requires—so data plans charge less and network usage is lower.
Can voice calls work in areas with poor internet?
Yes; VoIP can use adaptive codecs and operate close to the network limits, making voice calls robust even on 2G or weak Wi‑Fi.
Is video call always better for business meetings?
Video enhances collaboration with visual cues but can be overkill for simple status updates; balance depends on meeting goals and bandwidth.
What if my camera fails during a video call?
Most services switch automatically to audio‑only, ensuring the conversation continues if the video stream drops.
