While you’re updating your voicemail greeting, make sure you let callers know when they can expect to receive a call back from you or from someone else from your company. Most professionals opt for a 24-hour callback window. Clearly state this in your voicemail greeting to set expectations with your callers.
Ok so let’s say you’ve made a few calls and have left several messages and you don’t want to leave another one… if that’s the case, at least hang up before the end of their “leave a message after the tone” instructions so that they don’t get notified of a voicemail just to hear you hanging upon them.

In the Calling User Portal, you can manage your voicemail settings, like when you want your voicemail to be active, message storage settings, and how you would like to be notified of new voicemail messages. You can also set up your voicemail greetings.
