Im very interested in the Exchange Unified Messaging features offered in SBS 2008.
Currently we have a SBS 2003 R2 install, with 5 users, and am interested in upgrading, but i understand we would need to invest in some VOIP hardware. Currently we have two lines coming in. One for internet and calls, and one for receiving faxes.
Can some one please explain to me what hardware we would need and roughly how it works? Ive heard people splash around PBX / IP PBX and ive tried to do some research but still dont understand what they are and how they work? I understand i would also need VOIP phones? Can anyone recommend any models?
Im just looking for some information about hardware requirements for UM, any advice / explanations / experiences would be greatly appreciated.
