Speed Requirements - Ensure Adequate Internet Speed

Internet access is a requirement for any VoIP service and the broadband pipe should be of a sufficient capacity to be able to service your voice and data requirements. Calculating the exact bandwidth required for a particular deployment is somewhat subjective - bandwidth can vary during the day, and internet use is typically bursty - however the information below can be used as a rough guide.
Voice channels represents the maximum recommended number of simultaneous calls that can be made over the broadband pipe
- Max users is calculated based on a ratio of between 2 and 3:1 of users:voice channels
- Dedicated connection assumes no data / internet traffic on the broadband pipe
