Factory-trained technicians. On-site inventory. 24/7 support.



When you need support, you need it right now. We get that. That's why we always maintain an extensive on-site inventory of replacement parts and components - even for older systems. Our service department is open round the clock, seven days a week, so you'll always get the support you need. What's more, we offer training on every system we install. We even provide customized user guides. 


Central Telephone is there when you need us. Now that's good business.
