T48G - Fails to hangup call (disconnect) when handset is placed in cradle

Hi,

When sending an image to the T48G, the phone will not terminate the call when the handset is placed in the cradle. The user does not notice the call is terminated.

We are sending XML via a NOTIFY message as follows:

<?xml version="1.0" encoding="ISO-8859-1"?>
<YealinkIPPhoneImageScreen doneAction="" destroyOnExit="yes" Beep="yes" Timeout="60" LockIn="no" mode="regular">
<Image verticalAlign="middle" horizontalAlign="middle" >https://www.voiceelements.com/pbx/yealink/browserxml/tsunami.jpg</Image>
</YealinkIPPhoneImageScreen

The XML and the works correctly and the image is displayed. Its just when you hang up there is a problem.

Please advise.

Thanks!
