For a small business, what is better - VOIP or physical phon

Hi Guys,
I am starting a small business with three employees. I would like to know whether it would be best to have a VOIP system or actually put in phone lines with a phone system. I will be working in the office and at my home at times while the others will be in the office mostly.
Regards,
