[Freeswitch-users] extracting sip subject

2) you can do this with regex and substitution in the dialplan.  There
are some complex examples... just wrap () around the parts you want
substitution and then use $1 $2 $3 in your actions.

3) not at the moment, it would probably be trivial to add, but don't
think you need it for this.
