If callee is busy or not available, then this additional branch might
still ring giving wrong signal to caller.  Caller should hear ringing
sound only after callee responds with 180 ringing.  So the additional
branch should be added in reply route when SER receives 180.

I too noticed a couple of weeks ago that dsm/mods/mod_sbc was
introduced.  It sounds like a very useful module possibly allowing
implementation of a more flexible sbc than what sbc application offers.

It would be nice to have a Readme.mod_sbc.txt or an example dsm where
mod_sbc is used.
