Configuring GrandStream HandyTone 486(487),286(287), ATA for 3CX Phone System

IMPORTANT This guide has been tested with firmware version 1.1.0.37. Be aware that different firmware revisions may have different web interface formats and functionality. This FAQ is based on a new ATA OR one that has been reset to factory defaults.

How to factory reset:

  1. Connect an analog phone to the HandyTone phone port. Pick up the headset and press “****”. This will start up a Voice Prompt Menu. Now press “99”. Dial the now the MAC of the device, where|
    a. A=22
    b. B=222
    c. C=2222
    d. D=33
    e. E=333
    f. F=3333

  2. For example, if the MAC address is 000b8200e395, it should be encoded as “0002228200333395”

How to setup ATA for FAX:

  1. Connect the LAN to the Wan port of the HandyTone
  2. Connect an analog phone to the HandyTone phone port. Pick up the headset and press “****”. This will start up a Voice Prompt Menu. Now press “02” to listen to the IP address that was assigned to the device by the DHCP server
  3. Enable the wan side Web access, dial “****” and then “129”
  4. Launch a browser and go to the IP Address determined or configured in steps 1. The default username is “admin”
  5. Select the “Advanced Settings 1” tab.
  6. Set the “SIP Server” field to the IP Address or FQDN of the server on which 3CX Phone System is installed – in this example 10.172.0.2
  7. Set the “Outbound Proxy” field to the same value as in step 13 above
  8. The “SIP User ID” field should match the “Extension Number” field of the extension created for this phone in the 3CX Phone System Management Console
  9. In the “Authenticate ID” and “Authenticate Password” fields enter the ID and Password that you entered for the extension in the 3CX Phone System Management Console. These fields must match the Authentication ID and Password set for that extension in the 3CX Phone System Management Console
  10. The “Name” field is optional. A suitable value would be the name of the user using this phone
  11. Set the “Preferred Vocoder” to choice 1: PCMU, choice 2: PCMA. The settings for choices 3 to 7 will not come in use since they will not be used by 3CX Phone System
  12. Set “User ID is phone number” to “Yes”
  13. Set “Sip Registration” to “Yes”
  14. Set “Unregister on Reboot” to “Yes”
  15. Set the “Register Expiration” field to a suitable value. For testing purposes you may want to use 60 seconds, but once configuration is tested a larger value would be more appropriate to limit unnecessary network traffic. A good setting for general use could be 3600 seconds (1 hour)
  16. Set “Allow outgoing call without Registration” to yes
  17. Set “Enable Call Features” to “Yes”. This setting enables features like transfer, on hold etc from the analog phone connected to the FXS port of the device
  18. Set “Send DTMF” to “in audio” or “Via RTP (RFC 2833)” or both. SIP info is not recommended although 3CX Phone System can support it
  19. Scroll to the bottom of the page and click the “Update” button. You will be prompted to reboot the device. Click the “Reboot” button
  20. After the HandyTone has restarted, switch to the 3CX Phone System Management Console, and click on the Phone System -> “Line Status” (the default page). In the section “Extensions”, your new extension connected to the PBX should be listed with a green status light
