So you must go route 2, easy peasy

David told you how to do it with FS, I told you, how to do it with Asterisk,
(if you wait a couple of hours, message will be approved and posted on the list)

We give you hints about your options to solve your issue. And there is much
more ways of solving the issue.

As I told you before, could also be done with Kamailio, but with TONS of hours of work,
that no one will do it for you. Just because there are other tools out there (B2BUAs),
that better fit the needs.

So, if your are unable to follow a hint, read the docs, try the things on your own
and ask the right questions on the right place, better you hire someone 
that could solve it for you.

Good try.

It's really simple, for someone that knows how things works. With a minimal of dialplan
programing knowleade of Asterisk, FreeSwitch, YATE, SEMS, etc. and how to interact with
that B2BUA from outside the SIP channel.
On the other email I pointed you how you could solve it with Asterisk, using 
CDF+AMI PlayDTMF command

Giving you a hint, doesn't mean solving you the problem. Means, you must do
you homework.
