Preparing Your Network for VoIP
So here’s what you need to do to prepare your circle
. The first and most important step is to try and accurately estimate your usage requirements. For a regular person using Above at home, the upload and download speeds are too insignificant compared to the overall bandwidth available. Even mobile data connectivity is sufficient. However, a large organization can expect a multitude of people to be using the phone lines at any given time and all of it adds up. It also helps to remember that upload speeds are a an order of magnitude slower than download speeds. When calculating the amount of bandwidth necessary for Above, you have to take the lesser of these two into consideration. Once that is done and you have provisioned sufficient bandwidth for it, you’ll want to segregate the Above traffic from all others. This is so that it cannot be affected by any unexpected surge in Internet connectivity like a file download that would completely hog all available bandwidth.
This kind of Virtual LAN or VLAN is a common
best practice when dealing with sensitive real-time communications. For a hosted PBX system, there’s really nothing else you need to do other than to ensure that your Internet connectivity is ready to accept Above traffic. All of the heavy lifting is done in the background by a third-party SIP provider. As long as you keep tabs on Above usage and the amount of bandwidth you have allotted to it, everything else should go smoothly.
