Lines and IP Bandwidth Calculator
Each VoIP calculator is presented inside a tab at the top of the application. The Lines and IP Bandwidth Calculator works out the bandwidth that you should provide through an IP-based network for a given number of voice channels. The calculator works up to 100,000 Lines and 20,000 Mbps.
You can also perform reverse calculations to work out the number of voice paths that can be derived from your existing IP-based connection.
Erlangs and IP Bandwidth VoIP Calculator
This calculator returns the bandwidth that you should provide through your IP-based network to transport a known traffic volume in Erlangs or CCS. The calculator works up to 25,000 Erlangs and 20,000 Mbps!
Again, you can perform reverse calculations to work out the busy hour traffic that can be offered to your existing group of lines derived from an IP link of a known bandwidth.
