UCaaS low-volume carries restrictions beyond the volume

The requirementstatement

A UCaaS low-volume registration is limited to a low daily ceiling, a restricted throughput class, one number per human user, and no API or automated traffic.

Why this rule existsrationale

The tier exists for individual humans typing messages, and the conditions enforce that rather than merely the volume — so a business that stays under the daily cap but sends through an API has still breached it. It is chosen for the low cost and the conditions are discovered afterwards.

How to fix itremediation

Use this tier only for human-sent, one-number-per-person messaging. Register a standard campaign for anything automated, however low the volume. Done when no API traffic runs on a UCaaS registration.

Check this yourselfattestation

No tool can settle this one for you. Here is the check, and what wrong looks like.

Does anything automated touch the numbers on your UCaaS low-volume registration?

1Look for API traffic, integrations and scheduled sends on those numbers — an integration somebody added later is the usual breach, and it is invisible in the volume figures.
2The tier requires human-sent messages, one number per person, no automation — staying under the daily cap is not sufficient.
3Register a standard campaign for anything automated, however low the volume.

What wrong looks like: A business well under the daily ceiling has still breached the tier because it sends through an API. The tier was chosen for the price and the conditions were read afterwards.

Notesnotes

Tier conditions applied by the carriers. What the user has to confirm is that nothing automated touches the numbers on this tier — an integration somebody added later is the usual breach, and it is invisible in the volume figures.
