As You see, FS replies with +OK. But the variable is unchanged.

SET, part one

Send:
sendmsg YjJjNzJlOTQ0YWE1N2I2MGVlYTAwMzI2NWFjMmY4ZjM
execute-app-name: set
execute-app-arg: Caller-Privacy-Hide-Number=true
call-command: execute

Part of received headers (JSON output):
...

{ name: 'Caller-Privacy-Hide-Number', value: 'false' },

...
{ name: 'variable_Caller-Privacy-Hide-Number', value: 'true' }

...
Variable is not overwritten. Instead a new "variable_" is created.

SET, part two

Send:
sendmsg NmJmZWU5YzMwYTlkMTk2MDg0ZmIzZmQwMTFiMTFkMmM
execute-app-name: set
execute-app-arg: privacy_hide_number=true
call-command: execute

Part of received headers (JSON output):

...

{ name: 'Caller-Privacy-Hide-Number', value: 'false' },

...

{ name: 'variable_privacy_hide_number', value: 'true' }

...

Again, variable is not overwritten. Instead a new "variable_" is created.

Can it really be true this is not possible?
