Love them or hate them, voice mail systems are a great way to free up staff time and ensure your callers always get an answer. Nothing says "we don't care" like a phone that just rings out. Voicemail and IVR Systems are there to cover the calls when you or your team can't. They can answer the call and guide the customer to the right department, they can comfort them while they wait and if nobody is available they can take a message and pop it in your inbox (and you don't have to pay them a salary either).
The perfect employee.
