Forward calls to a pre-determined number during a power outage or when the connection to the cable modem is lost so you will never miss a call.
Choose your busy greeting from the drop-down menu next to If busy use greeting from: System—This plays the system default greeting. Personal—If this option is selected, choose the file to upload.

When you slow down your speech, you are giving the caller time to acknowledge the information that you are giving. Therefore, breathe naturally.
Humor also leaves a lot of room for misinterpretation—which subsequently weakens sincerity and authority. A caller can be very turned off by merely misinterpreting your joke. Why take this risk? Additionally, this could even cause callers to question your character. Say, for example, the president of a company’s mobile phone voicemail greeting was funny. What’s to happen if the caller didn’t like or get the joke? What if they found it offensive? Another scenario is that a caller is reaching out to you for the first time—i.e. they have no idea regarding your personality. What next? The point is, with this type of greeting, humor is bound to be more divisive so just avoid it altogether. c. Poorly Pacing Your Message and Bad Time Management: Don’t speed through your message. Speak clearly so callers know what to include in their message and when to leave the message. At the same time, don’t drag your message out. No one wants to sit through a diatribe. Just get to the point clearly.
