Häufig gestellte Fragen

What bandwidth does a VoIP call use?
A G.711 VoIP call uses about 64–87 kbps. G.729 codec uses only 8–32 kbps with compression.
What is a typical QoS policy?
A common policy: 20% voice, 30% video, 50% data. Voice and video get priority queuing.
Should percentages add up to 100%?
They can, but leaving headroom (e.g., 10%) for management traffic is good practice.
