You might be able to pull it off using the various subst and other
But those may not be sophisticated enough to do the trick, in which case
you might just need to pass this SDP body off to a third-party scripting
language like Perl or Python. There, you can make the modifications you
want, return a new SDP body to Kamailio, remove the old SDP body, and
append your new one.
