[Freeswitch-users] Setting channel variables using event socket

[Kenn Leth Hansen]

Hi,


I am struggling with the task of setting a channel variable through an
event socket. It seems no matter what I do, FS will not overwrite the
existing variable.

What I have tried so far:

*API*
*Send:*
api uuid_setvar ZWVlZDUwMTUyNjdjNWU4ZTBmZWY4NTQ1ZDA2NmJiYWI
privacy_hide_number=true<cr><cr>

*Reply:*
Content-Type: api/response Content-Length: 4 +OK

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?
