Push XML on T38G

[ruffle]

Yes... but I'm not trying to display preset photos as a screen saver. I want to push/pull stills from the office entrance camera either as a 'screen saver' when it's idle (as I do on Snom 870's) or pushed to the phone when someone comes through the door (external trigger).

If the T38G would accept a YealinkIPPhoneImageScreen from a push XML I could display one frame at least.

I notice that there is an XML Idle Screen and URL on the Account page of the T38G but turning that on and providing a URL to a TextScreen XML file seems to have no effect - the phone doesn't fetch the XML at the end of a call. Anyone got any ideas what this is for and how you use it?
