Cisco IOS: TCL Script not working after upgrade to sr4300-universalk9.16.09.06.SPA.bin — 3

We have a ISR4331 that we use as a voice gateway. Currently it is on version isr4300-universalk9.03.16.04b.S.155-3.S4b-ext.SPA.bin. The TCL script send a tone to an FXO port at certain times that we use as a shift-bell. I would like to upgrade to isr4300-universalk9.16.09.06.SPA.bin but when I do the TCL does not function.

Because this is a production system we need to troubleshoot during non-business times.

After the upgrade, it doesn’t even initialize the call

I ran a kron debug and found:
