Permanent forward T41S

[microdata]

Permanent forward is set to on
on code is set to forward.always.on_code
off code is set to forward.always.off_code

Target is set to the mobile phone number, i tried it in the national and international format.

If i call the number of the T41S it shows the call on the display and is not ringing but the mobile phone does not ring ether.

Are there any special settings for the Provider "Deutsche Telekom" ?

You would have to follow up with your provider to see what signaling/packets they are getting back from the phone and if there is anything special needed. Only the provider will have the information you need to track this and figure it out (unless you are running your own PBX, in which case you need to check the PBX logs).
