Below are instructions on setting up a Grandstream HandyTone 486 ATA on the 2talk service. For more details on the Grandstream HandyTone 486 product click on the Link below:

The Grandstream site should offer a comprehensive User Guide as well as the latest firmware releases for the Grandstream ATA’s. You may also find that the instructions below apply to the other Grandstream ATA’s such as the 286, 386, 488, 496 models etc. It is recommended that your firmware on the ATA be at least v. or higher. Below are some links to help you get your Grandstream HandyTone486 setup and running:

Quick Install Guide:

Full User Manual:

Firmware Downloads Page:

To upgrade your firmware you first get your HandyTone ATA setup with access to the Internet following the install guide above and then set your TFTP server IP to that specified on the firmware downloads page above. You should be able to connect a phone to the ATA and use the audio menu to find out and setup different parameters:

Press ***02 - To read back the IP address of the ATA (which you can then connect to with a Web Browser to configure)

Press ***16 - To read back firmware version information

Press ***13 - To set TFTP server IP address for firmware upgrade

Read the User Guide in the above link for more information.

Once you have managed to setup and connect to the web interface on your Grandstream ATA, you can then configure it as follows to connect up to the 2talk service:

Step 1: Login to your ATA using a web browser. By default you will only be able to do this from the ‘LAN’ side of the ATA. If you do not know the IP address of the ATA then Dial ***02 to find this out.


The default password on the Grandstream ATA is ‘admin’. If this does not work then you may need to do a factory reset of the ATA to revert it back to the default settings. For more information on how to do this see Section 8 of the User Guide.

Step 2: Setup your basic settings by clicking on the basic settings tab. In here you should have DHCP setup as the default network mode and unless you want your Grandstream ATA to act as a router you should set it up as ‘Device Mode: Bridge Mode’. Here you can also setup the time zone and daylight savings settings as appropriate.


If you make any changes then click ‘Update’ at the foot of the page.

Step 3: Now switch to the Advanced tab. The following screenshots show the an example of the advanced config page in sections. You will need to setup your advanced settings to match these (where appropriate). The main settings you will need to setup are:

Admin password: your-own-admin-password (You should reset this from the default ‘admin’ for security reasons)

SIP Server:

Outbound Proxy:

SIP User ID: your-own-2talk-number (You should enter your own 2talk phone number here. e.g. 028890000)

Authenticate ID: your-own-2talk-number (Again enter your own 2talk phone number here. e.g. 028890000)

Authenticate Password: your-2talk-password (This is the password you received during signup)

Name: your-name (You should enter your Full Name here. e.g. John Smith)

The preferred codec order is up to you. But for most people you should select the lower bit rate codecs first (e.g. iLBC, G729) and then the higher bit rate codecs (e.g. G711):

1. iLBC

2. G729A/B
