[svn-commits] wedhorn: trunk r318106 - /trunk/channels/chan_skinny.c

[SVN commits to the Digium repositories]

Author: wedhorn

New Revision: 318106

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=318106
Log:
Add setsubstate_callwait.

If a call is made to a line that already has a call and the device is
offhook (ie activeish call), the call is set to CALLWAIT rather than RINGIN.
