Voicemail is basically a digital version of an answering machine. When someone calls you, if you are not available to take the call yourself, the voicemail system answers, plays your outgoing message (or a generic message telling the caller to leave a message), and then records the caller's message. You then access the voicemail system (details depend entirely on which system you use) and listen to your messages.
The term Voicemail was coined by Televoice International (later became Voicemail International) for introduction of the first nationwide Voicemail® service in 1980.
To access voicemail messages on a house phone, you typically dial your own phone number and then follow the prompts. Alternatively, you can often reach your voicemail by dialing a specific code, such as *98 or *86, depending on your phone provider. It’s best to check with your service provider for the exact number or code used for accessing voicemail.
Ringless voicemail drops are messages sent to a list of cell phones bypassing the ringing of the cell phone and send directly to the cell phones voicemail. If someone sent a ringless voicemail to your cell phone would never ring and you would just see a notification that you have a voicemail waiting for you. Your business can contact Atlas Voicecom at AtlasVoicecom.com for a demo on how it works.
