[Freeswitch-users] Channel Variable: variable_pre_transfer_caller_id_number

Hi, <action application="info"/> when I call the info app in my dial plan then I can see the following vars in my log variable_pre_transfer_caller_id_name: [] variable_pre_transfer_caller_id_number: [18] But when I try to access one single channel variable its always empty. Why? ${variable_pre_transfer_caller_id_number} Thank you for your help.
