Hello world, So I am some what of a network administrator at my job. Our network is comprised of windows computers and Macs, but no Linux machines at all. They want me to setup a phone server for there VOIP service we get from our ISP but I have no clue how to use linux at all. Any recommendation on destros for a beginner trying to do advance things. But I would also like to learn Linux in the process. Thanks in advance.
