All services are provided on a monthly or annual subscription basis. The provider doesn’t offer a free plan, but you can request a demo to explore VirtualPBX’s interface before signing up for the paid service.
This is a tough category because all telephone service companies have complaints on public forums. Remember that people who comment on these forums are more likely to be unhappy with the service, while happy people don't frequently take to publicly announcing their happiness with a product. Acknowledging that all the companies we looked at have some complaints, the winner for best service is Vonage, one of the first phone companies to offer VoIP for business.

Practice makes perfect. Again, another obvious one, but it has to be stressed. If you want your voicemail greetings to come off as genuine, you have to practice. If you simply throw together a greeting that sounds and feels rushed, your customers aren’t going to let you get away with it. You will come off as if you don’t really care, and that won’t convince anyone you’re prioritizing the customer experience.
When’s the last time you cleared out your voicemail box? Do you find that you have to listen to the same message several times just to write down a name or phone number? With a voicemail transcription service, you'll no longer have to deal with these issues.
