The HandyTone 286 manual can be found here.

Configuration Details

STEP 1 - Connect your router with the supplied Ethernet network cable to the HandyTone. Now connect your phone to the HandyTone. Finally plug the supplied power cable into the HandyTone.

STEP 2 - Wait 60 seconds after plugging your HandyTone in.

STEP 3 - Pick up the phone connected to the HandyTone and dial the * key on your phone 3 times (* * *).

STEP 4 - Have a pen and paper ready. You will hear a message - "Enter a menu option", then enter 0 2 on your phone. You will now hear a message giving you the IP address of your HandyTone such as - "192.168.001.010" write this number down.

STEP 5 - Open a web browser on your computer such as Internet Explorer and enter the IP address you heard in step 4 as the address (I.E. where you would normally enter www.yahoo.com). Please note: some browsers will require you to remove leading zero's ( 0 's ) in the IP address. For example if you heard "192.168.001.010" you should change this to "192.168.1.10".

STEP 6 - You should now see a page that looks like this:

STEP 7 - Enter the password for the HandyTone in the password field. The default administrator password for the HandyTone is "admin" (without quotes).

STEP 8 - After entering the password you should see a screen that looks roughly like this:

Step 9 - Click on Account 1 to configure your first line.

Step 10 - Fill the followings fields.

• SIP Server: atlanta.voip.ms (or use one of our multiple servers)
• SIP User ID: 100000 (Replace with your 6 digits Main SIP account UserID or Sub Account user name, i.e. 123456 or 123456_sub)
• Authenticate ID: ********* (Replace with your 6 digits Main SIP account UserID or Sub Account user name, i.e. 123456 or 123456_sub)
• Authenticate Password: ********* (SIP Account Password)
• User ID is phone number: No
• Name: (Enter any name you like)
• SIP Registration: Yes
• Register Expiration: 3 (This setting is in minutes not seconds)
• NAT Traversal : No
  • Notes: NAT Traversal can be set to Yes if you are behind a router (even if you do not set a value in the STUN server field). Indeed according to the reference guide, with no specified STUN server, then the phone will only periodically (every 20 seconds by default) send a blank UDP packet (with no payload data) to the SIP server to keep the mapped port open on the NAT.
• Home NPA: Empty (Some tests show that this field should be kept empty or you will encountered difficulties with some numbers ending with a busy signal [tested with 418 in home NPA, and a 1-877 number] )

Message Waiting Indicator
