How to set up the SJphone application
Getting started
A softphone is a piece of software that, when downloaded to your computer and combined with our free trial, enables you to experience Internet telephony technology without purchasing additional hardware. You will require a suitable headset with a microphone, or a USB phone device.
You can download SJphone for a number of operating systems at here.

Basic configuration
- Press the Menu button on the main display. This is the button in the middle of the phone that looks like a screwdriver

- Select ‘New’ from the Profiles Menu, then give the profile a name such as ‘Gradwell’, Select the Profile type ‘Calls through SIP Proxy’
- Select the ‘SIP Proxy’ tab from the Profile Options displayed
- Set the Proxy Domain to the registration server name that you would have been advised to use in your welcome email, such as newsip.gradwell.com. You need to ensure the port number is set to 5060
- Set the Proxy for NAT to the outbound proxy you would have been advised to use, for example natproxy.gradwell.com, and set the port number to 5082
- Select the DTMF tab and set "Send DTMF as" to be RFC2833
- Select OK and you will be presented with the Service information screen
- Enter the extension number that you wish to use and your password, select the tick box "Save service information permanently" then click on OK
- Close the menu window using the cross in the upper right corner
SJphone should now register to our network and enable you to make and receive calls, in order to test the quality of your audio you can dial 160 and follow the instructions.
Advanced settings and troubleshooting
If the SJphone software does not register, then you will need to check your personal firewall settings on your PC to ensure that the software is not blocked from accessing the Internet.
If you experience any audio problems such as one way audio, then you will need to ensure that your network is configured correctly - this is called port forwarding and further information is available in our wiki article Firewall and NAT Settings.
