Endpoint registration feature description

Prolog information
When an endpoint may power up, reboot, or carry out another operation requiring it to register to the Device Adapter, the following occurs:
  • The endpoint tries to register.
    • The registration request is only sent if the set has a node ID and TN configured, and some mechanism to reach the servers. This may use DHCP or provisioned IP addresses.
    • The endpoint initiates UNIStim registration with the Server 1.
    • If it is unable to register there and “Server 2” is configured on the endpoint, it will attempt to register with Server 2.
    • If it has not yet registered, it waits a period and retries, starting with Server 1.
  • The Device Adapter load balancer assigns the request to a selected Device Adapter instance, based on keeping as even a loading as possible on the cluster.
  • The Device Adapter instance initiates SIP registration with the Session Manager on behalf of the endpoint.
  • The Session Manager registers the endpoint and sends the configuration information of the endpoint (key map, etc.) to the Device Adapter.
  • The Device Adapter accepts the data and completes the UNIStim registration with the endpoint.
The Device Adapter follows the CS 1000 endpoint handling.
Password protection using the Node password (IP Phone Installer Password) controls who can change the TN on the IP Phone. The IP Phone Installer Password protection controls registration with a virtual line TN on the Call Server. The password can be set on the Device Adapter through CLI commands such as nodePwdSet. The password is stored as plain text on the CS 1000 disk but encrypted on the Device Adapter.
When password protection is not enabled, a UNIStim IP Phone displays the node ID and Terminal Number (TN) of the IP Phone for five seconds as the IP Phone starts. When the password protection is enabled on the Device Adapter (or IP Line Gateway in the CS 1000), the node and password are displayed. If the data was already set, the phone waits for 5 seconds, and if the user does not begin changing anything, the registration proceeds.
The user may choose to configure the IP connectivity, Node ID, and TN of the endpoint during registration. If the Node is to be changed, the user does so. Otherwise, the user may change the TN.
If the control password is enabled, the user must enter that before changing the TN; on successful password entry the TN can change. If the password is disabled, the TN can be changed immediately.
If the Node password is configured on the Signaling Server, once the endpoint logs in the IP Phone Telephone OptionsSet Info menu does not display the Set IP Information or Ethernet Information options.
Note:
The Avaya Aura® SIP phone user enters an extension number and password during registration. It does not have a node and TN.
