Grandstream GXP Series Setup Guide

Prerequisites

Before you start, you need to know your VoIP username, password and the server that your number is connected to. You can do this from your Goldfish account, by clicking My Goldfish, then “Your Numbers”, then the telephone number that you wish to connect to. The VoIP username and VoIP password are near the bottom of the page, in a section entitled VoIP Settings.

Step 1: Locating the IP Address of your Device

Plug the Ethernet cable into the LAN port on the device and the other end into your Broadband router/Network switch and obtain the phone’s IP address as follows:

Newer Grandstreams (GXP2130/2140/2160)

Press the UP and it will show the IP address of your device, something like 192.168.1.15.

Older Grandstreams (GXP1400/1405, GXP2100, GXP2120/2124)

Press MENU (circle key in between the 4 arrows), select STATUS and then NETWORK STATUS and look for IPv4. The phone’s IP address should appear on the phone’s screen, something like 192.168.1.15. Type the IP address into a web browser’s address bar on your PC/Mac. Should this be correct, it will show you the login screen for your device as shown below.

The default passwords can be found below your login screen, type the password and then press Login. The configuration page should appear. Once logged in, click on the accounts > Account 1 > General.

Configure your account as shown below:

Set “Account Name” to anything you wish
Set “SIP Server” to sbc.goldfish.ie:8060
Set “SIP User ID” to your VoIP Username
Set “Authenticate ID” to your VoIP Username
Set “Authenticate Password” to your VoIP Password
Set “Name” to anything you wish
Set “Voice Mail UserID” to 8000

Once all information has been added, click on ‘Save and Apply’ to save the settings for this section.

Step 2: Setting NAT Traversal

Click on ‘Network Settings’ on the left hand side and enter the following information:

Set “NAT Traversal” to Keep-Alive

Once all information has been added, click on ‘Save and Apply’ to save the settings for this section.

Step 3: Setting the Local SIP Port

Click on ‘SIP Settings’ and the ‘Basic’ and enter the following information:

Set “Local SIP Port” to 8061. Click on Save and Apply to save the change.

** The local SIP port number of 8061 should be used for a single device registered to a network. However, if you have multiple devices on the same network, the local SIP Port MUST be unique. For example, the first phone registered would, as above, have the local SIP port of 8061. The second phone registered would need to have a different local SIP Port registered, which would be 8063. A third phone would be registered against the local SIP Port of 8065, so on an so forth.**

Step 4: Setting SIP Security Settings

Click on ‘SIP Settings’ and then ‘Security Settings’ and make sure that ‘Check SIP User ID for Incoming Invite’ is set to Yes.

Once all information has been added, click on ‘Save and Apply’ to save the settings for this section. Upon this, click on ‘REBOOT’ in the top right hand corner to reboot the device.

For older Grandstream handsets

Configure your account as shown below:

Set “SIP User ID” and “Authenticate ID” to your VoIP Username
Set “SIP Server” to sbc.goldfish.ie:8060
Set “Authenticate Password” to your VoIP Password

Step 2: Setting the local SIP Port and NAT Traversal

Configure your Local SIP Port and NAT Traversal options as shown below:

Set “Local SIP port” to 8061
Set “NAT Traversal” to Keep-Alive

Step 3: Configuring the DTMF mode

Configure your DTMF settings as shown below:

Set DTMF to “via RTP (RFC2833)”

Click UPDATE at the bottom of the configuration page, then click to view your changes and then click REBOOT on the phone menu screen. Make sure you click UPDATE before clicking REBOOT to make sure your changes are implemented correctly.
