Are voice greetings for business phones really something that a person should be investing in? It really comes down to whether or not a person feels like they are talking professionally or not. Some people will have a professional record everything, while others might just have them write a certain script that can be used.
If a person uses a voice that is not their own to record a greeting, it can be beneficial depending on the tone. Those people who might not have the best voice speaking wise could really benefit from something like this.
A script is something that can also be very beneficial. Instead of relying on thinking of something on the fly, a professional will be able to help out with exactly what is needed from a business point of view. It is definitely something to consider for the most part.
