    - union: A SIP endpoint which is the address of your SIP infrastructure. SIP endpoints can be one of two types: static endpoints or registered endpoints. | Endpoint | Description | | -------- | ----------- | | Static endpoints | Static endpoints are defined by a static value which can either be an IP address or a domain name. | | Registered endpoints | Registered endpoints use a credential list to determine the endpoint. | ---
      - object
        - `address` string, required: The address of the SIP endpoint can be an IP address or a domain name. EST uses IP authentication and will only accept calls from the specified address or domain.
