Your clients don’t have a lot of time, and neither do you. Use the following short voicemail greetings to get to the point quickly and invite them to leave a message.
Here’s a simple clinician voicemail script if you want to keep your message to the point. Hello. You’ve reached Highland Family Counseling Services. We are currently unable to take your call, so please state your name, phone number, and a detailed message after the beep. We will return all calls within two business days.

Closing out of your apps is like turning your iPhone off and back on — it gives your apps a fresh start. If one of the apps that you have open crashes in the background, it may prevent other apps you have open from functioning properly. It can be difficult to identify which specific app or apps are malfunctioning, so we'll close them all to save time. Double-press the Home button to view the apps your currently have open. Use your finger to swipe up on the apps to close them. You'll know all your apps are closed when you only see a preview of your lock screen.
Context does matter here. If the caller would reasonably expect you to answer the phone (such as if they were calling a store or other place of business), an apology for not being able to get to the phone makes the most sense.
