Most businesses will automatically play a recording if you try to call their office when they are closed. An after hours announcement is a professional way to notify callers of important details, rather than making them wait for the call to failover to a voicemail box or other destination.
If you're looking to go all out to give the best possible first impression to your customers, hire a professional voice actor. Our customers love the voices available on Fiverr, a website that matches businesses with creative talent. You can get a professional recording done for as little as $5. If you're looking for a high-end product, check out The Voice Realm which offers the best voice talent on the planet. The quality is astounding.
