[svn-commits] wedhorn: trunk r316994 - /trunk/channels/chan_skinny.c

[SVN commits to the Digium repositories]

Author: wedhorn

New Revision: 316994

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=316994
Log:
Add setsubstate_busy.

Move handling of setting busy state from skinny_indicate to it's own sub.
Also, modified behaviour to not hangup the sub and let the dialplan
have a chance in doing what it wants (eg busy(10); hangup() in the dialplan
now gives a busy indication for 10 secs and then hangs up.
