For me, voicemail protocol doesn’t fall into a “pet peeve” category like a candidate arriving for an interview with bad breath or dirty fingernails. A voicemail greeting tells me something very specific about the communication savvy and sensitivity of a prospective candidate.
5. "Hello, [Person's name] is chasing new adventures and is no longer with [Company name]. Please forward all future requests to [New or interim person's name] at [phone number]. Thank you!"

Enhanced Voicemail lets you listen to messages, create personal or corporate greetings and access your voicemail box from anywhere there's phone or internet access.

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.
