Vista 20SE phone not working

I have a Vista 20SE that had been working for years. All sensors and keypads continue to work fine.
I needed to change telephone connections. Now when I connect incoming telephone line to Terminals 23 and 24 the telephone line goes dead, even without connecting the handset to 21, 22.
Is there a module in the Vista 20SE that I can replace to make the system work or is it that I did not connect the handset to 21, 22?

Properly wired through a RJ31X jack, the alarm panel is the connection between the premise phones and the telco switch. Unless you are using the Ademco module that lets you Arm/Disarm with a premise phone, the wiring below is correct.
