3CX + T46G with EXP40

[Headon_Support]

Hello,

i've tried to autoprovision a T46G with the EXP40.

The BLF Buttons on the Phone itself works perfect.
But its not able to get the EXP 40 provisioned over the 3CX.

When i remember right, it worked perfect for the T2X and T3X series.

Does somebody has the same issue, or the is it possible to get the XML Code for the EXP40?

Thank you very much.
