Please read http://wiki.freeswitch.org/wiki/Mod_skinny/Development#TODO
and keep in mind that some other features are closely related to Busy:
- CFwdAll, CFwdBusy, CFwdNoAnswer:
- DoNotDisturb: this also affects ringing
- Ring policies: they will be easily implemented once the busy state
is available
- "Better behavior (when: other leg busy, ...) ",
- maybe more

Of course, you don't need to implement all those at once.

There must be two things:
- set call state to busy accordig to various conditions (the busy
trigger) on the called phone (using switch_channel_hangup, around
skinny_ring_lines or related)
- handle this call state on the calling side (probably already done in
mod_skinny.c line 784, function channel_on_hangup_callback)

You can ask on @freeswitch-dev mailing list (or IRC), to code it the
right way (the busy management should work from and to mod_sofia
also).

> Thanks for your response.

Thanks for you proposal ;-)

Once you have something working, put it in Jira. I will review and commit.
