I would like put something in place.
This how it would work :
- The client call us
- He is asked for a pin number (any, 6 digits)
- [option - the digits are controlled]
- the digits are put in the sip header
- a call is make to an extension with the modified sip header
I took a look at IVR and Call Flow Control but I did not found what I’m searching for.
I already nearly made it with 3CX but this system do not allowed to modify headers so it was useless.
First question do you think I can do such a thing with Freepbx?
If yes Do you have an idea on how to?
Many thanks by advance.
