numbers.e164_taken
The E.164 number is already in inventory.
numbers.e164_taken means the E.164 number you tried to add already exists in Sautikit's inventory.
The box routes an inbound call by the dialed number alone, so a duplicate E.164 across two workspaces would be ambiguous about which one should receive it. Number uniqueness is therefore enforced globally, not just within your workspace — the number may already be:
Double-check the E.164 you are submitting — a typo (missing +, wrong country code, extra digit) is the most common cause. If the number is genuinely already active on this workspace, it does not need to be added again:
