When you leave a voicemail do not use your full name because that immediately raises a red flat that you are a salesperson making a cold call. Instead, say your first name only followed by your company name. This will make your customer feel that you are much more familiar with each other than you really are. Saying your last name would defeat the whole purpose of demonstrating familiarity.
If you create a call answering rule but don't specify an action, your caller will hear the following prompt: "You have reached the mailbox of . Please call back later. Goodbye." and the call will end.

If you want to improve your voicemail performance, get deliberate in your practice. This means creating a highly structured practice routine that offers ample opportunity for repetition and immediate feedback.
Here’s the thing: no matter how perfectly-crafted your sales voicemail is, plenty of people are still going to ignore it or stop listening midway through. That’s actually okay, though. We already know that other types of messaging, like emails, get a higher response rate. But where voice messages win is in quality – when you do get a response, that means the person has a very high level of interest.
