I swapped out a dead TVS100 to a TVA50 on a KXTD1232.

It was fairly simple configuration and it seemed to go ok. 2 custom service menus, 1 day and 1 night. They use the same company greeting with the only difference is at night calls go straight to the VM instead of the extension 1st.

I can't get the KXTD to change to Night service or synch the time?
The TVA is set to synchronize
The TVA is set to PBX CONTROL
The TVA is set to KXTD DPITS integration.
If I let the timer do the change it works fine but if I use PBX control the phones go into night but not the TVA

I must have missed something but Panasonic Tech support line won't talk about the TD series anymore.

Thanks for any clues.
