I’m not sure why Cisco didn’t include “custom file” option to update lines like you can phones, but if you have the list of numbers to change call forwarding rules, you can use the following queries which are a part of the numplan table. Call Forward All rules are in another table callforwarddynamic which i’ll cover later:
cfbvoicemailenabled = call forward busy external set to voicemail (boolean)
cfbdestination = call forward busy external destination
cfbintvoicemailenabled = call forward busy internal set to voicemail (boolean)
cfbintdestination = call forward busy internal destination
cfnavoicemailenabled = call forward no answer external set to voicemail (boolean)
cfnadestination = call forward no answer external destination
cfnaintvoicemailenabled = call forward no answer internal set to voicemail (boolean)
cfnaintdestination = call forward no answer internal destination
An example query below:
run sql update numplan set cfbvoicemailenabled = (‘f’), cfbintvoicemailenabled = (‘f’), cfnavoicemailenabled = (‘f’), cfnaintvoicemailenabled = (‘f’) where dnorpattern = “1111111”
