The dial key doesn’t work in the phonebook. The round button just edits the contact details. Forced to type the number even if it is in the phonebook.
To be sure I understand-
You enter the directory and use the navigation keys to locate and highlight the contact of interest and when done, you then press the SEND button and nothing happens?
Yes, I locate contact whether I press green button or the menu Dial or the menu Edit and dial or Dial then green button the number is not dialled. Even if I select specific number eg Work the phone does not call it.
The # key is not enabled because it is needed for ITSP commands and call transfer.
Update the firmware as you are a few behind and then test.
