I defined a keys on 5324 to switch the day mode to Day and Night 1 mode.
I set "Dialed Day/Night Service - Activate" feature access code to **5 and the keys defined as CDE Speedcall to **50 for the Day Mode key and CDE Speedcall **51 for the Night 1 key.
The both keys work fine, but require pressing Cancel key or hang up. I wonder if there is any way to avoid pressing the Cancel key?
From the system help, there is step 4) to hang up:
To change the mode of service on a local node:
1) Lift the handset.
2) Dial the Dialed Day/Night Service - Activate feature access code.
3) Do one of the following:
Press 0 for Day service.
Press 1 for Night 1 service.
Press 2 for Night 2 service.
4) Hang up.
