And again arguing ... your are asking for the FULL solution, and we refuse to
give it to you.
David have pointed you to a way of how to solve it, you just DON'T undestand
how to do it, but that's your fault, not our.

A B2BUA MAN! ... how many times you need to hear that?

A sip proxy, could not inject things in the dialog whitout braking it, that why
we told you, you need a B2BUA, but it's clear, that you don't get the point.

And I have told you, that and Asterisk its perfectly capable as a client to do so,
the problem is that you NEED TO KOWN how to control Asterisk for that, and I have
told you how. CDF+AMI, there is no prebuild solution for that, so get your hand on
if you are willing to have a solution.
With FreeSwitch it's lot easier to do manipulations on A-Leg or B-Leg of the call from
the ESL than with Asterisk, but both could do it.
