numbers.credential_limit_reached
This number already holds the maximum number of active SIP credentials.
This number already holds the maximum number of active SIP credentials.
numbers.credential_limit_reached means the number already holds as many active SIP credentials as it is allowed.
A number can have several SIP credentials, one per device, each with its own password. There is a cap on how many can be active at once.
Revoke a credential you no longer need with DELETE /v1/numbers/{id}/sip-credentials/{credential_id}. Revoked credentials do not count toward the cap, so this frees a slot immediately.
To avoid reaching the limit, read the allowance before you create. GET /v1/numbers/{id}/sip-credentials reports both figures as active_count and limit.
If a lost password is why you wanted a new credential, you do not need one: POST /v1/numbers/{id}/sip-credentials/{credential_id}/reveal returns an existing credential's password without disturbing the device that uses it.
