New Revision: 319087
URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=319087
Log:
When a error in T.38 negotiation happens or its rejected on a channel the
state of the channel reverts to unknown this should be rejected.
this is important for negotiating T.38 gateway see #13405
This patch adds a option T38_REJECTED that behaves as T38_DISABLED except it reports state rejected.
Trivial Change to res_fax to honnor UNAVAILABLE and REJECTED states.
(closes issue #18889)
