Capacity#
Capacity determines how many inbound calls a DID number can receive at the same time. Without sufficient Capacity, calls that exceed the limit are rejected — meaning real callers hear a busy signal or get disconnected before reaching your system.
DIDWW gives you three channel types to match your traffic patterns and control costs:
Flat-rate — Fixed monthly channels for predictable call volumes, assigned to a single DID or shared across multiple DIDs through a Capacity group.
Pay-per-minute — Metered channels for variable or unpredictable traffic, billed per minute with no setup or monthly fees.
Hybrid — Flat-rate channels for baseline traffic with metered channels as automatic overflow, so you pay a fixed rate for expected volume and only pay extra when traffic spikes.
Note
Capacity applies to inbound calls only.
