More Choices

When you ask us to provide a quote we can prepare two or three different quotes for any budget requirements. 

We'll quote on a new system, using all-new components and phones or a combination of new and gently used off-lease components. Off-lease phones are fully upgradable to the newest relase IP Office and  provide a very affordable system package.

If you have an older Nortel or Norstar system we can suggest upgrades to your existing system. You can even use your Nortel phones on a new or off-lease Avaya IP Office!
