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 [login to view URL] 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: with [login to view URL]: 000178: Dec 28 12:23:38.577: %SYS-5-CONFIG_I: Configured from console by onyx on vty0 ([login to view URL]) 000179: Dec 28 06:25:00.001: Major 1, Minor 0 000180: Dec 28 06:25:00.001: Timer Event ShiftChange10 000181: Dec 28 06:25:00.001: Kron delay for next ShiftChange10 86400000 000182: Dec 28 06:25:00.002: Call parse_cmd 'csim start 7777' 000183: Dec 28 06:25:00.004: Kron CLI return 2 '' 000184: Dec 28 06:25:00.004: Major 4, Minor 7 000185: Dec 28 06:25:00.004: Respond to end of CLI Process 000186: Dec 28 06:25:00.005: Call parse_cmd 'csim start 7777' 000187: Dec 28 06:25:00.007: Kron CLI return 2 '' 000188: Dec 28 06:25:00.007: Major 4, Minor 7 000189: Dec 28 06:25:00.007: Respond to end of CLI Process on the box : application service paging flash:[login to view URL] param prompt-1 flash:[login to view URL] ! kron occurrence ShiftChange1 at 6:00 recurring policy-list ShiftChange ! kron occurrence ShiftChange2 at 9:00 recurring policy-list ShiftChange ! kron policy-list ShiftChange cli csim start 7777 cli csim start 7777 !
