[SVN commits to the Digium repositories]

New Revision: 278501

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=278501
Log:
Fix invalid test for rxisoffhook in FXO channels

This fixes some cases of no outgoing calls on FXO before an incoming call.

Remove an unnecessary testing of an "off-hook" bit from DAHDI for FXO
(KS/GS) channels.In some cases the bit would not be initialized properly
before the first inbound call and thus prevent an outgoing call.

If those tests are actually required by anybody, they should define
DAHDI_CHECK_HOOKSTATE in channels/sig_analog.c .
