Change Background Display On Polycom SoundPoint SIP Phones

Another task I recently completed for a client of mine was to modify the background image for Polycom SoundPoint SIP phones connecting to the companies VoIP network externally. Depending on the model of the Polycom SoundPoint you can modify the background image that displays on the LCD panel using a URL. In this case the phone type was a Polycom SoundPoint 550 and he phones connecting via an external network were not displaying the background image that was set for phones on the internal network. Below is information on where you can find where the background image is set and an example configuration file that explains what could be changed to have different phones locate the background image on the Polycom SoundPoint SIP phones also known as the home display.

The configuration file for their phone was actually using a different outbound proxy and SIP registration server address so they could operate remotely. One of the issues pointed out to me was the fact that the phone’s time was never correct and after some basic investigation I was able to locate the issue which is described below as well as how to override the DHCP NTP address settings via the Polycom SountPoint CFG (configuration) files.
