1) Test Internet connection
1 call = 100 Kbps (up & downstream)
Pay attention internal calls should also be taken into account!
If you have a lot of concurrent calls (incoming & outgoing calls) make sure the bandwidth of your Internet connection is enough
If your Internet connection is or will be shared between DATA network & VOICE network, it’s crucial to prioritize the VOICE traffic
If you are unable to prioritize the VOICE traffic you will have to foresee a dedicated Internet connection for your VOICE traffic only
