Action URL - Incoming Call

[Futureweb]

Hello,

using Yealink T46G Phones on 3CX with XML-Push of Caller Information.
It's already working on the "Call established" Action - XML information is shown on the Phone.
But it's not working on the "incoming call" Action ... Phone simply doesn't show any Information ...

Using the same URL for both Actions ... and the Request is sent to the Server (see it in the Apache Logs)

Is there any Problem with showing XML Information on "incoming Call"?

Thank you
Andreas Schnederle-Wagner
