Introduction

This document describes how to configure an Analog Telephone Adapter (ATA) to use H.323 clear text authentication when you register with an H.323 Gatekeeper.

Prerequisites

Requirements

Readers of this document should have knowledge of these topics:

• Basic ATA operations such as use of the interactive voice response (IVR) and web browser interface for configuration.

• Basic H.323 concepts.

Components Used

This document is not restricted to specific software and hardware versions.

Conventions

For more information on document conventions, refer to the Cisco Technical Tips Conventions.

Configure H.323 ID for Registration

With the use of the ATA web browser configuration interface, edit the UseLoginID, LoginID0, and LoginID1 fields. The simplest method to use is the H.323 password separator =, whereby the ID you enter is composed of the H.323 ID and the password in the LoginID field. For example, komodo=123 is interpreted by the appropriately configured gatekeeper as H.323 ID komodo and H.323 authentication password 123.

Enable H.323 ID Registration Method

This ATA configuration example shows the log-in credentials for ports 1 and 2, respectively:

• E.164 addresses: 1002 and 1003.

• H.323 IDs: komp1 and komp2.

• H.323 passwords: 333 and 444.

ATA186 web interface fields:

UID0: 1002
UID1: 1003
UseLoginID: 1
LoginID0: komp1=333
LoginID1: komp2=444

This is an example of web browser screen output:

Note: Remember to save the configuration and re-register with the gatekeeper.

Configure the Cisco IOS Gatekeeper

In the Cisco IOS® Gatekeeper configuration, you need to enable H.323 security. Enabling H.323 security is a prerequisite to enable the use of the password separator "=" on the gatekeeper. Each H.323 ID/password pair also requires a username/password pair configured in the global parameters of the gatekeeper.

Cisco IOS Gatekeeper Configuration Example

This is an example of the configuration required on the Cisco IOS gatekeeper in order to enable the ATA you have already configured to register with it.

Note: Only the configuration relevant to this document is shown.

hostname KomodoGK
!
username komp1 password 0 333
username komp2 password 0 444
!
gatekeeper
zone local KomodoGK cisco.com 192.168.1.99
zone prefix KomodoGK 1*
zone prefix KomodoGK 2*
security h323-id
security password separator =
no shutdown
!

Verify the ATA Registers Correctly

In order to confirm that the ATA registers with the gatekeeper with the use of the H.323 IDs, use this Cisco IOS command on the gatekeeper:

KomodoGK#show gatekeeper endpoints

GATEKEEPER ENDPOINT REGISTRATION
================================
CallSignalAddr  Port  RASSignalAddr   Port  Zone Name   Type   F
--------------- ----- --------------- ----- ---------   ----   --
192.168.1.1     1721  192.168.1.1    1739  KomodoGK         TERM
	       E164-ID: 1003    
    H323-ID: komp2
192.168.1.1     1720  192.168.1.1    1719  KomodoGK         TERM
    E164-ID: 1002    
    H323-ID: komp1

Note: The ATA 186 registers as an H.323 terminal (TERM) and not as an H.323 gateway. This is done deliberately so that only the calls intended for the ATA 186 are sent to it.
