Android phones can access voicemail by holding down the 1 key on the dial pad until the phone dials your 10-digit phone number. You will automatically connect to your mailbox and be prompted to enter your temporary password; this password is the last 4 digits of your phone number followed by the # key.
I can’t come to the phone right now because I’m down in the basement printing up a fresh new batch of 20 dollar bills. If you need any money, or if you just want to check out my handi- work, please leave your name, number, and how much cash you need after the tone. If you’re from the Department of the Treasury, please ignore this message.

The easiest way to record and program professional voicemail greetings for your phone system is to write down a script. Choose someone to record your script - the one who can speak without hesitating or stuttering, has a friendly voice and can annunciate and pronounce each name and word clearly.
For example, you could say something like “Would you like to know how we could do this for your company, too?” in order to incentivize them returning the call.
