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 Soho66 account, by clicking My Soho, 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 inbetween 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.

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.**
