For example, a message like, “Hi, this is Jim. You know what to do.” Well, not everyone is going to know what to do—i.e. they won’t leave you inclusive information. Additionally, they may not leave you a message at all. Aside from this, humor can again be detrimental to your message, this time lending itself to ambiguity and costing you clarity. For example, if a message read, “Hi this is Jim, sorry I can’t answer your call right now. Please leave your name and number and I’ll call you as soon as I can, but you already knew that right? Do I need to tell you what to do?” This is worse than the previous example as this is confusing and can also come across as rude and unprofessional. Complicating a greeting with phrasing like this is sure to cause some harm. e. Ignoring Personality & Identity: Don’t use computer generated greetings. Some users leave default messages (‘you’ve reached the voicemail box of 777-777-777, please leave a message). Believe it or not, even this can cause problems. Callers may be unsure if the voicemail box belongs to you; therefore, they don’t leave a message. Also, some may even be uncomfortable leaving information through a message in a nameless voice message box. As such, impersonalization can cause ambiguity, which again can hurt the effectiveness of your voice message system. This doesn’t mean you have to make an elaborate greeting if you don’t want to, just insert your voice and name so at least callers know they’re calling the right person.
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.

Solution: Poor sound quality is unlikely the fault of a reliable business voicemail service that uses VoIP technology, Baldwin says. So garbled voicemails are often due to callers’ poor mobile phone reception while leaving their message—and you may just need to call them back, assuming you can figure out their phone number. But if the problem does seem to be your voicemail, make sure you’re using a business phone and voicemail service that uses VoIP and not relying on, say, your mobile phone’s voice mailbox.
