Lots of different ways to do those things... here's one basic example:

; toggle the ivr by dialing this extension                                      
exten => 3950,1,DBget(ISIVRON=FEAT/ivron) ; if success, step 2, else 102
exten => 3950,2,GotoIf(${ISIVRON} == yes?3:102)
exten => 3950,3,DBdel(FEAT/ivron)
exten => 3950,4,Background(npi-ivroff)
exten => 3950,5,Hangup
exten => 3950,102,DBput(FEAT/ivron=yes)
exten => 3950,103,Background(npi-ivron)
exten => 3950,104,Hangup

Then insert something in your dialplan statements to read the DBget
values, and branch as appropriate. 

That example essentially turns an IVR on/off by dialing extn 3950.
