Common Questions About Legacy Systems

Can you really fix my 20-year-old Nortel system?

Yes. We maintain a large inventory of refurbished parts and have certified technicians who specialize in older Nortel/Norstar architecture. We can often fix systems that other vendors suggest replacing.

Do I have to switch to VoIP?

Not necessarily. While VoIP offers modern features, if your current digital or analog system meets your needs, we can help you keep it running. We can also discuss hybrid options if you want to slowly transition.

What happens if my system fails completely?

We offer 24/7 emergency support. In many cases, we can replace the main processing unit (KSU/PBX) with a refurbished unit to get you back up and running with minimal downtime.
