Gatekeeper Mode (#20) allows the user to make a direct call to another user with ADSL dynamic IP address registered in the gatekeeper. The IPTEL with dynamic IP address will register its current IP address to the gatekeeper under the assigned alias name and alias telephone number. When the Gatekeeper Mode is enabled, you may dial the alias telephone number to call the party with its alias telephone number registered in the gatekeeper. A Gatekeeper is needed for users with ADSL Dynamic IP. For Gatekeeper (GK) Mode VoIP calls, you need to provide IPTEL for the followings; the gatekeeper IP, the alias name, the alias number, and the Time to Live (TTL). The Time To Live defines the time period of IPTEL for repeat registration to the gatekeeper. You may display or change the Gatekeeper IP, TA alias name, and alias number from the PC Telnet Commands. 9.10 Gatekeeper Command Mode Enter #200 to disable gatekeeper mode.

Note that you need to press the “#” to complete configurations from the telephone set. it is not needed in PC telnet session. 10

PPPoE (#05) allows IPTEL users to connect ADSL dynamic IP without NAT router as follows. For ADSL dynamic IP users, the Internet Service Provider (ISP) will provide user a PPPoE username and a PPPoE password for connection to Internet. With the username and the password, PPPoE will be able to get a dynamic IP from ISP. To enter the username and the password into IPTEL, you need to run “telnet 192.168.1.150” from PC Windows [Start] [Run] screen, assuming that the current IP address is 192.168.1.150. The default IP address for IPTEL is 192.168.1.150. If you forgot the current IPTEL IP address, you may enter the new IP address from telephone set by using #11 commands. Example: ADSL dynamic IP with Gatekeeper Mode registration 1. Run From PC: Telnet 192.168.1.150 2. #051 Set PPPoE 3. #06abc@efghijk Enter PPPoE Username “abc@efghijk” 4. #07xxxxxx Enter PPPoE Password “xxxxxx” 5. #201 Set Gatekeeper mode 6. #21061066159237 Enter Gatekeeper IP Address “61.66.159.237” 7. #21voip Enter Alias Name “voip” 8. #24123456 Enter Alias Number “123456” 9. . Exit to enable PPPoE Note that the new dynamic IP from ISP will replace for the IP 192.168.1.150 after enabling PPPoE, and the “telnet 192.168.1.150” will not be valid any more until disabling PPPoE by pressing #050# from the telephone set. Now your registered VOIP alias number is 123456, and you may have your friend dial 123456 to call you at this IPTEL. 11 IPTEL PC Telephone ADSL Modem IPTEL IP: 192.168.1.150 (#11) Subnet Mask: 255.255.255.0 (#12) Router IP: 192.168.1.254 (#13) LAN
