[Freeswitch-users] Problem with conditions depending on values generated by dialplan

[Anthony Minessale]

Yes, you seem to understand it perfectly. (one man's problem description is
another man's documentation)

The dialplan is a state of the call (ROUTING) that comes before EXECUTE.
The reason you are having problems is you are confusing the dialplan with
asterisk that treats its dialplan as
a scripting language.  The FS dialplan is like a pre-processor for the call
that scans the entire thing and compiles it
into a single list of instructions before changing to EXECUTE and actually
executing the instructions.

The best way to fix the problem is to shift the paradigm in your head to
match the one in reality.

The best way to do what you want is to set the variable as you do now then
transfer the call to another extension.
Since that action will put the call back into ROUTING the next extension
will see the variable.

Also you can use the execute_extension application in a similar manner to
transfer without actually transferring.
