Dialogic Media Gateway - Incompatibility with IE10; Bottom of browser window is blank after logging into the DMG1000/2000
Symptom
When using Internet Explorer 10 (and later versions) and Firefox, a blank web page is displayed when logging into the WebUI for Dialogic 1000 and 2000 Media Gateways with software version SU10 or earlier.
Reason for the issue
Some web browsers or web browser versions are incompatible with the DMG1000 or DMG2000 Gateways and may have display issues with the WebUI web page. Below is a summary of the supported browsers as of February 2016.

Solution
Running the web browser in Internet Explorer compatibility mode will typically resolve the issue and display the DMG1000 or DMG2000 Gateway webUI correctly. Other web browsers such as Google Chrome may have plugins that emulate Internet Explorer and allow the use of compatibility mode.
The following article available from Microsoft as of Feb 2016 describes how to set compatibility mode using Internet Explorer (select the pull down for appropriate IE version when you go to the article): http://windows.microsoft.com/en-us/internet-explorer/use-compatibility-view#ie=ie-11
