6. "Hi, this is [your name]. I'm either on a call or away from my desk. Please leave your name, number, and a brief message and I'll get back to you. Thank you."
17.01.2019. This is audio from a telephone scam. When the phone rings the caller ID is visible and it looks like its a call from a local number in your area

It is a voice message for the caller when you aren’t there to receive the call. Caller can leave a voicemail message for the person for which he/she has made this call.
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.
