Authenticate the Endpoint at the Gatekeeper with an E.164 Address and

Password

Follow these steps to configure the ATA 186 to register with the E.164 ID and password:

Set the AutMethod field to 1 (the default is 1).

The hexadecimal value that is to be configured for this field is 0x0. This field is set to indicate that the

ATA will now look for the password.

Set the UseLoginID field to 0.2.

Configure UID0 and UID1 with the E.164 IDs for the ATA 186.

The ATA 186 registers as two different H.323 terminals, one for each port.

Configure PWD0 and PWD1 with the password for the each port.

Note: The ATA uses the password to generate the token. This token is sent to the gatekeeper for

authentication.

Configure NTPIP with the NTP servers IP address.

The gatekeeper and the ATA must have clocks synchronized to the same NTP server.

Note: The timestamp is used for token generation. For more information, refer to the Gateway to Gatekeeper

(H.235) and Gatekeeper to Gatekeeper (IZCT) Security Troubleshooting Guide.
