Next steps

• If the trunk has Disabled status, Enable or disable an outbound trunk before sending calls. Status behavior is listed in Status values.

• For a trunk that uses Credentials & IP-Based authentication, DIDWW generates SIP credentials after the trunk is created. To view them, View outbound trunk credentials, then configure the credentials in your voice equipment.
