By presenting a clear, welcoming message containing relevant information about your business, you are showing callers that you value their time. If your recording is vague, confusing, or drags on, customers will lose interest and hang up the phone instead of leaving a voicemail message.
One of the chief considerations in recording an answering machine greeting is your audience. Who will be listening to your answering machine or voicemail salutation? Is this a business line or a home phone line? Furthermore, just how much information do you want to give out to potential strangers, like telemarketers, who may be calling your home? Long answering machine greetings may be inconvenient for callers.

Hi, thanks for calling the residence of the Jennings Family. As you can tell, no one’s home to answer your call, but just leave your name, number and message and we’ll get back as soon as we can. Thanks
Your voicemail greeting on your business telephone system is the very first thing your business associates and clients will hear when calling your company. For the first time callers, probably your potential customers, you only got a chance to provide a great first impression that will be provided by your voicemail greeting message. For the ones who frequently call your company, you would want to make your voicemail greeting prompts as efficient as possible in order for you not to waste your client’s precious time in listening to your whole voicemail greetings every time they make a call.
