Dear yealink,

we have an ip door phone who you can open with a code once you are connected to the doorphone.
I have configured this to a DSS-key on the T26P as DTMF and then the value the doorphone wants.
This has been working like a charm untill yesterday.

Additional information :

Phones T26P with EXT panel.
Software : 6.72.0.50

I have already installed the new software 6.73.0.50 on one phone to test this and with that phone it doesn’t work aswell.

If I press the DSS key where the DTMF is active it doesn’t do anything.
Before you could see that the phone entered the value.

Kind regards
Thomas
