No matter what your call processing components, from Auto Attendants, to IVR, ACD and Voicemail, your organization should present a unified sound that represents your brand. Phone menu prompts, produced professionally, give your call processing clarity and brand identity every time your customers and prospects call. The way your organization is heard, especially during first impressions, can directly impact client successes and failures.
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).

You might also consider giving them the option to skip your voicemail message completely by pressing another key (again, check with IT). You also want to make callers aware what you will return their call, instead of telling them that you will try to return their call--and let them know when you are likely to do it, if possible. If necessary, provide additional or emergency information in your voicemail greetings. My dentist, for example, lists his cell phone number for emergencies.
On the Greeting page, under both the Business Hours and After Hours tabs, choose whether you want to use the default greeting, upload an audio recording, or record your own greeting. Click Next. 8
