Why BOOST saves you money — and why per-seat providers can't offer it.
Base Capacity
You set a base of concurrent lines that covers normal call volume.
Real-Time Detection
BOOST detects spikes the moment concurrent calls exceed your base.
Automatic Expansion
Capacity expands instantly for the spike, then scales back down.
Per-seat providers bill every employee whether they're on a call or not. BOOST bills concurrent usage — most teams never have every seat on a call at once.
