The first, unscripted example is vague and awkwardly worded. The second, scripted example is clear, definite, and smooth. Research some sample scripts for business voicemail greetings before you write your own. And here are some specific voicemail greetings for doctors, lawyers, and dentists.
Timing is everything. The moment you receive the lead alert is the best time to make the follow-up call. If you call them days later, your chances of getting them on the phone are greatly diminished. By calling them right away, you’ll talk to more leads which will inevitably boosts sales. Role-play your voicemail scripts so you sound like you’re making your 20th call, not your 1st. Ask your friends and colleagues for honest feedback on your voicemail scripts. Continually review what’s working and what isn’t -- there’s always room for improvement. If you have the lead’s email address, follow up with an email, and let them know in the voicemail you’re going to do so. If you don’t have an email, let them know you’ll follow up with a text.

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.
To check your voicemail messages from another phone: Call your 10-digit wireless number. When you hear your voicemail greeting, press the * key to interrupt it. If you reach the main voicemail system greeting, enter your 10-digit wireless phone number, then interrupt your greeting by pressing the * key. Enter your voicemail password when prompted.
