Configure Grandstream General settings

Setting up VoIP account

On this page, you will find the settings for Grandstream devices. This configuration is based on Grandstream GXP2120 and GPX2140. Depending on the type of Grandstream and software version, it may look slightly different from the images below. For setting it up, it is important to copy the data exactly as shown in this example.

How to set up a Grandstream

• On the display of your Grandstream, you will find an IP address.
• Enter the IP address in your browser.
• Login with 'admin' and password 'admin'.
• If this does not work, for newer Grandstreams, the password is located at the bottom of your device.
• If you have ever had to set your own password, use that. If you cannot remember it, then a factory reset is the only solution to log in to your Grandstream.

• Go to Settings.
• Go to Preferences.
• Click on Date and Time.
• Fill in NTP server ntp.voys.nl.
• Specify the correct Time Zone and that you want a 24-hour display.
• Optionally, indicate whether you also want the date to be visible.

Setting up VoIP account

• Go to Accounts.
• Choose Account 1.
• Choose General settings.

• Open a second browser and go to freedom.voys.co.za
• Go to "Admin".
• Go to "Voip-Accounts".
• Go to the Voip-Account that you want to configure to your device.
• Go back to the Grandstream page.
• In the Account Name field, enter the Voip-account number.
• In the SIP-server and Second SIP server fields, enter sip.voys.co.za.
• In the SIP User ID and Authentication ID fields, enter the Account ID.
• In the Authentication Password field, enter the password of the VoIP-Account.
• In the Name field, you can give your device a name. Examples include: your own name, Reception or the internal number of the device (e.g. 201).
• Press Save and Apply.
• The red VoIP-Account dot should now be green.

Basic Settings

• Go to Network Settings.
• For DNS mode, set it to SRV.
• For NAT Traversal, select Keep-Alive.
• Click on Save and Apply.

SIP Settings

Go to Basic Settings under SIP Settings.

• Set SIP transport to "TLS/TCP".
• Check if SIP URI schema when using TLS is set to "sip".
• Set keep alive interval to 15.
• It is also useful to adjust the local SIP port.
• It is recommended to separate the local SIP port for each device. The Local SIP Port depends on your VoIP account ID. For example, if your account ID is 123400007, you would enter 5067 here. You take the last digits of your VoIP account and add it to 5060. Then you get 5060+007=5067. This makes each Local SIP Port unique and easier for your router.
• Click on Save and Apply.
