I would like to start learning unity, but I'm really confused about which version to study on. What version of unity is commonly installed for medium size businesses. If I understand and know Unity, would this mean as well that I know U express and Unity connection or each of these 3 products work and are configured differently.
an other question, Cisco replaced unity by unity connection in the CCIE blue print, does it mean Unity is a dying product ??
I'm a newbie in IPT, so any comment is welcome.
thanks in advance
