T41P-Call Forward Off Code don't work ??

[flgh]

Hi,
i have a single fon T41P on Digibox Premium (like Bintec be.ip) und use Call Forwarding extern in the German Telekom PSTN with the codes switch on *21*target Number# and switch off #21#. I use not the intern codes of Digibox *11 and #11.
Parameters in Yealink:
forward.always.on_code = 0*21*
forward.always.off_code = 0#21#

When i switch on the Call Forwarding, the function is OK. But the code for switch off dosn't work. In the log of Digibox i can see that the Yealink sends the switch off code with the target Number. I think that is the bug. Can you fix it? In firmware T41-36.81.0.110 it works fine. In all newer firmwares it is not OK.

Trace Digibox:

I read in this Issue the same problem (for T46G) >>> (Why only fixes for 46G and not for all other Products ??):

Not sure, try opening a ticket on the support site and see what they say. If anything this sounds more like a bug/problem on your Digibox as sending the off code along with the number the phone had itself forwarded to makes sense. If your PBX doesn't like the extra digits, it should be dropping/ignoring them.
