First of all, check that calls from all the DN keys show the correct extension number when you call another digital set with a display fitted.

Find the FFC code for "Do Not Disturb" and check that the feature hasn't been activated by mistake.

Also change or add in the FFC code for Call Forward Hunt Over ride (CFHO). Try e.g. ##

Then change the TN of the extension in the CLS from CFHD to CFHA

Once that's done, from another extension dial e.g. ##3900
