This voicemail greeting will be played for both external calls (originating from outside your company) and internal calls (people call from another extension within your company). If you expect to receive most of your calls from clients and partners, it is best to have someone to handle urgent calls by setting up the general voicemail greeting accordingly.
When you create a voicemail message, the next thing you need to ensure is that your prospects are aware that they have reached the right person so no confusion takes place.

Recognize Their Need. When someone calls your business, the voicemail should give them a sense of validation. This means that your voicemail should extend gratitude for their interest in your business, or an apology for not being there to answer your call. These two simple courtesies can go a long way in the creation or establishment of client/business trust. Make it Informative for the Caller. Your voicemail must include all the information the customer will need for your particular business. For instance, if you’re a brick and mortar establishment, it’s wise to include your store hours. It’s also a good idea to leave them an alternate way to contact you, especially if it’s after hours. After all, you don’t want to miss just one potential customer. Here are some suggestions for elements to include in your voicemail: Business name Hours (if brick and mortar) Alternate method of contact, such as email Your name
