Yuan,

  I know and the goal aof any new feature is to be channel agnostic.
Obviously SIP response codes are VERY SIP specific.  Maybe there is
another way to do it - specify a response label perhaps.  One could
then define this label in sip.conf, iax.conf, zapata.conf, etc to make
it do what it should do for that channel.  That would be cool.
