The problem there is that VoIP traffic is much more sensitive to network bumps and potholes than most general office traffic. That translates to garbled conversations, difficulty connecting over Wi-Fi, or (worst case) dropped and lost calls. If your business is small and your network is essentially contained in one or two wireless routers, then your configuration and testing headaches might be fairly easy (though still there). For medium and larger networks, these tasks can be complex and time-consuming, which translates into added cost in terms of man-hours.
Instead of stating the obvious, enhance your message with information your callers can use, such as how to reach someone immediately, when you will be returning calls, or where they can obtain after-hours service. Services that offer multiple custom greetings like Tendant allow you to store multiple greetings so you can have a greeting just for a holiday that you can use every year. Specify the information you want callers to leave. Your voicemail greeting presents a great opportunity to gather important details that will help you better serve your customers. This may include account numbers best times to return the call, and of course, a brief summary of the issue or purpose of the call.

But with integration being at the heart of VoIP and UCaaS, you can't make a purchasing decision here without thinking about the future. On one side, consider each vendor carefully to see what they've done over the last half-decade in terms of product development and keeping up with VoIP and UCaaS trends. On the other side, think about what you'll need in the next five years.
