Ooma Office is engineered for great voice quality but you will need a high-speed Internet connection. You should have at least 256 kbps upstream and downstream for each simultaneous call during peak usage times. For example if you have 8 users and you think up to 3 people will be on the phone at the same time during your busiest time, you would need 3 * 256 kbps = 768 kbps of upstream and downstream bandwidth.
