Because of the nature of voice data, VoIP traffic requires regular transmission of small data packets. These packets can often be delayed by other large data packets on the network which take more time to send over a low bandwidth link. While these packets are being transmitted, no VoIP traffic can be sent, introducing jitter to the call.
If you limit yourself to only use 70% of your available bandwidth, you can reduce the risk of this jitter affecting the quality of the call. But bandwidth can be expensive so this could be a costly option.
VOIPBOX optimises the way data is transmitted over the network.

|---|---|---|---|---|
| Without VOIPBOX each call uses | 42.4kps | 106kps | 63.6kps | 42.4kps |
| With VOIPBOX each call uses | 8.1kps | 64.1kps | 32.1kps | 3.1kps |
| Calls per 256kps | 28 | 3 | 7 | 17 |

Improving call reliability and security







"Since installing VOIPBOX we've seen a massive improvement at our call centre. Very few calls get dropped now and the negative impact it was having on customers has disappeared."

"SpiriTel looked at VOIPBOX as a solution to provide additional channels of VoIP capacity for sites that had limited available capacity or where the cost to provide that capacity was too prohibitive."
