SIP bandwidth calculator
When planning for your SIP implementation, one key metric you need to have ready is how many concurrent calls you need. This can be taken from your existing ISDN or PSTN setup, making changes where you think you are over or under capacity.
Once you have this figure, your service provider knows how many trunks to configure. This figure also helps your network team work out how much bandwidth they need to allocate for the SIP trunks.
Work through our SIP bandwidth calculator with your information to find out how much bandwidth you need and how it will changes as your business scales up or down.
