OCS Gateway Sizing using Erlang B equation

In OCS it is important that we calculate the size of our Gateways correctly when provisioning Enterprise Voice.
We can use Erlang B equation to to this. So, if you go to http://www.erlang.com/calculator/exeb/ then you can use a free online tool to assist you in calulating the Gateway size.
We can use this tool to establish the probability of a port being open. For loads of more information see the website. For more information on OCS see the Microsoft website.
