Establishing Authentication with Cisco H.323 Gatekeeper
You can configure the CiscoATA to establish authentication with a Cisco H.323 Gatekeeper. The
Cisco ATA supports two authentication methods:
•Cisco registration level-security
•Cisco admission-level security (per-call basis)
To configure either authentication method, use the following procedure:
Procedure
Step 1 Set the UseLoginID parameter to 1. This setting indicates that the LoginID0 and LoginID1 fields will be
used for Cisco ATA H.323 registration.
Step 2 Set the UID0 and UID1 parameters to the E.164 phone numbers that are assigned to the FXS ports on
the Cisco ATA.
Step 3 Set the LoginID0 and LoginID1 parameters to the H.323 ID. The H.323 ID is use d when the Cisco ATA
registers with the H.323 gatekeeper. This ID is also used as the accoun t ID for the RADIUS server.
Step 4 Set the PWD0 and PWD1 parameters to the passwords for the Phone 1 and Phone 2 FXS ports (the
passwords in the RADIUS server), respectively.
Step 5 Set the NTPIP and AltNTPIP parameters to the IP addresses of the NTP servers in your network.
Step 6 Select the authentication method using the AutMethod parameter (0 indicates no authentication; 1
indicates the Cisco registration level security method; 2 indicates the Cisco admission level security
method).
Note The authentication methods are Cisco Proprietary H.235 implementations, which use the Cisco
access/clear token structure rather than the VocalTec crypto token structure.
