Hi, I want to set a variable to a certain value within one callflow - (the variable will be a mobile phone number) and then use that variable within another callflow that will be accessed by another call maybe hours or days later (to transfer a caller to that mobile phone number). I have tested this and the variable seems to be reset after each call. What is the intended scope of lifetime of a VAD variable? Do I need to persist the variable in an external database or in the 3CX config.? Many thanks.
