Components Used The information in this document is based on these software and hardware versions: • ATA 186 with version 2.12 • Cisco 3640 with Cisco IOS® Software Release 12.1 as a gateway • Cisco 2600 with Cisco IOS Software Release 12.2 as a gatekeeper The information presented in this document was created from devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If you are working in a live network, ensure that you u

IP addressing can be done statically or dynamically, as explained in the Cisco ATA 186 Basic Configuration document. In the previous screen, the static IP address is used. 2. In the Cisco ATA 186 Configuration window, configure these fields: ♦ UID0 and UID1 Configure the E.164 addresses of voice ports 0 and 1. Both voice ports can not have the same E.164 address, as the ATA 186 can not hunt if one of the ports is busy. If both voice ports are assigned the same E.164 address, the call will always

GKOrProxy Configure the IP address of the gatekeeper. ♦ Once this is done, anything that is dialed from the ATA 186 voice ports is sent to the gatekeeper. 3. Click the Apply button and then reload the page. The ATA 186 takes 10 seconds to reconfigure itself. These examples are relevant configurations for the Cisco IOS gatekeeper and gateway: 2610−Gatekeeper interface Ethernet0/0 ip addreinterface Ethernet0/0 ip address 172.16.13.12 255.255.255.224 half−duplex h323 interface h323 h323−id pr

Note: The ATA 186 registers for the two voice ports separately. The ATA 186, therefore, gets authenticated twice as different H.323 terminals, as shown in this debug: 4w4d: AAA/AUTHEN/CONT (3800768902): continue_login (user='atagw1') 4w4d: AAA/AUTHEN (3800768902): status = GETPASS 4w4d: AAA/AUTHEN/CONT (3800768902): Method=LOCAL 4w4d: AAA/AUTHEN (3800768902): status = PASS 4w4d: AAA: parse name= idb type=−1 tty=−1 4w4d: AAA/MEMORY: create_user (0x83149EFC) user='atagw2'ruser='NULL'
