New Revision: 53714
URL: http://svn.digium.com/view/asterisk?view=rev&rev=53714
Log:
Adding a hook in rtp.c so that the midcom module registers to the core
and the SIP module checks whether or not we have midcom loaded.
Also, add a notifier so that RTP.c can notify SIP if the netsec
module is unloaded by force.
Thirdly, add a shutdown mode in res_netsec, so that no new calls will be handled
by the midcom device during shutdown.
