TCSS — Your Phone Simplified.
Hybrid PBX

Cloud resilience, on-site survivability.

An on-prem appliance for control, paired with hosted trunks and failover for reach — branch offices run on the cloud, headquarters runs on metal, and it all acts like one phone system.

How it fits together

One system, two places to stand

A simple picture of the model — the appliance and the cloud, connected.

On-site

The appliance you own handles local extension-to-extension calling and keeps working through most internet blips.

Cloud

Hosted trunking, failover, and reach across every branch — plus the same web portal used across all TCSS products.

Who it's for

Three shapes Hybrid solves well

Multi-site businesses

Headquarters stays on metal, branch offices run cloud extensions — one system, one number plan, no separate PBX per location.

Aging PBX migration path

Not ready to rip out an existing on-site system? Hybrid lets you move to cloud trunking gradually instead of all at once.

Connectivity-fragile locations

If a single internet drop can't be allowed to take down your phones, cloud failover keeps calls moving while the on-site link recovers.

This one's a conversation, not a checkout button.

Hybrid setups are sized to your sites, your existing hardware, and your failover needs. Talk to sales and we'll design the split that fits — no generic package to force onto your floor plan.
