You can enable or disable a greeting using the radio buttons at the top of the pane. The standard greeting cannot be disabled, however, the alternate greeting can be enabled in its place. Choose your own recording or use the system default.
Each of the Button fields corresponds to a number on the caller's phone keypad. In this example, we're using Button 1 for sales ("Press 1 for sales"). For the key that corresponds to your IVR announcement, from the dropdown select Time Switches, then New Time Switch. If you would like to always route to a queue, instead of a time switch, select Queues, then New Queue and skip to Queue Setup below.

In previous blogs, I’ve mentioned the importance of making a good first impression on a potential client. Most of the time, the first contact will be over the telephone. Since we are often in session, it is very likely that the first time a client hears our voice is on our voicemail greeting. This is why a professional greeting is so important. Identify yourself because you need to reassure the client that they have called the correct number. Clients will be a lot less likely to leave a message if they wonder who will get it. Use a warm friendly voice to say something like, “You have reached xxxx, licensed mental health counselor.” Tell clients what to do if they are in crisis. Although it seems obvious to us, clients may not realize that it could be several hours until we can return their call. I suggest something like, “If you require immediate assistance, please dial 911 or go to your nearest emergency room.” Ask for what information you need. Yes, the obvious name and number, but if it would be helpful to get their insurance information, ask for that, too. Give clients an idea about when you’ll return their call. Common business practice is within 24 business hours. Any extra messages or information you’d like clients to know. For example, if you are no longer accepting a particular insurance plan, the end of your voicemail greeting is a great place to convey that information.
