If you've got a true phone system (PBX, KSU, or any system with
a central computer "brain") then yes, the TV6000 hardware will work
seamlessly with your system.
If you have "off the shelf" phones rather than a true phone
system, then we'll provide you with the TV6500 hardware. The x500
adapter was designed to be a universal solution for providing
music-on-hold to analog and non-KSU phones. Since it’s introduction
in 2001 the x500 has been field tested on virtually every multi-line
phone ever sold. Out of these hundreds of phones, there are a very
few phones that the x500 either won’t work with or require special
attention to function properly.
