Legacy Phone System Support — Central Coast

We Still Support the Systems Others Have Abandoned

Mitel, Toshiba, Nortel, Panasonic, Intertel — if your business still depends on a legacy phone system, CENCOM's team has the parts, the expertise, and 40+ years of hands-on experience to keep it running.

Repairs & Parts Moves, Adds & Changes No Forced Upgrades 24/7 Local Support

If It's Still Running, We Can Keep It That Way.

When a manufacturer ends support, it doesn't mean your system has to stop working. CENCOM has been installing and maintaining these platforms since they were new — and we stock the parts, know the programming, and carry the expertise to service them long after others have walked away.

03

What does legacy support actually include?

CENCOM's legacy support covers moves, adds and changes (MACs), repairs, parts replacement, system programming, troubleshooting, and routine maintenance. We also provide honest assessments of your system's health and remaining useful life.

No. CENCOM will never pressure you to upgrade. If your legacy system is meeting your business needs, we'll keep it running. When you're ready to move to a modern platform, we'll help you plan a smooth migration — on your timeline, not ours.

My manufacturer no longer supports my system — what now?

That's exactly what CENCOM is here for. Nortel, Toshiba, and others have ended support for their legacy PBX lines — but that doesn't mean your system has to stop working.
