Also note, this system works over your NETWORK (not your phone wires). It will connect to up to 4 standard phone lines (or Internet-based VoIP service) but the connection between the phones and the UCM6204 "base" are done over a Ethernet NETWORK. The bad news is that if you only have phone lines running everywhere (2 or 4 wires only) then you will have to run new wiring. The good news is that if you already have a computer network and computers at each phone location, these phones can be connected to that existing network. (If you only have one network jack per location, the phones' built-in network switch lets you "pass" the network connection through the phone to your computer so both can be connected).
This is the message that your customers hear when they call during business hours. Greetings often have a short welcome message and list the menu options.

Most business greetings include a simple, firm handshake. Pay attention to names, and always introduce the “less important” person to the “more important person.” Business etiquette dictates that clients should be considered the “more important person,” even more so than the boss. Run this by your boss beforehand, however.
Instead of leading with tired old lines like 'Your call is important to us', brush up on your telephone etiquette and start your voicemail with a thank you.
