Bandwidth usage in VoIP
Every single VoIP call (agent-CTArchitect, supervisor-CTArchitect or CTArchitect-Phone network) requires a certain amount of bandwidth. The requirement mainly depends on two factors:
- Chosen codec with compression (G.729) or not (G.711).
- Voice activity detection (VAD).
The voice bandwidth usage would be as follows (with more information here):
| Codec Type | Voice Activity detection | Estimated bandwidth usage (per call) |
| G711 A-law | Off | 90 Kbps |
| G711 A-law | On | 55 Kbps |
| G729A | Off | 33 Kbps |
| G729AB | On | 24 Kbps |
