Click-to-Call Test numbers
The following phone numbers should all display as "clickable." (In Chrome they will display on the page as clickable, in Firefox, you must hover over the number to see it.)
If the above numbers are not clickable, check to make sure that the OnSIP click-to-call Icon says "on". If not, click on it to enable it.
If the above numbers are not clickable and you have installed the Skype click-to-call plug-in, you must first uninstall the Skype plug-in.
If the numbers are clickable, but your phone does not ring, try re-entering your credentials in the properties section of the plug-in.
