Looking for a great way to improve your business’s communications? The Bismarck Business Phone Systems team is proud of its long-standing reputation as the premier provider in this area. We offer many varieties on Avaya phones, including IP Office 500s–a workhorse that has been around since 1996! Our technicians have decades worth experience servicing these systems and also sell equipment if you need new handsets or upgrades with an existing account from us too; we’ll be happy help evaluate local companies who can provide either type service here locally .
