We know your time is valuable so instead of placing you on hold, let us call you back! Please leave your name, phone number, the reason for your call, and two different times that are convenient for you to receive a call back from us. Thank you!” Get a better idea of your caller’s schedule by asking them for a few different times you can call back. Their time is important, too!
If you have a main business phone number that’s shared with the customers or publicly listed, you’ll want to make sure it has a professional voicemail message to greet callers. Here are sample greetings you can use to help you craft your own.

Inserting an entry into the "v_voicemail_greetings" table should resolve the GUI "seeing" the greeting, but there is a voicemail_greeting_uuid column that is a long string of hex. I can randomly generate something, but does anyone know if it needs to be stored/registered/etc elsewhere? Sep 29, 2016 2,686 465 83 Aug 16, 2018 #5
