[svn-commits] rmudgett: branch 1.4 r1511 - in /branches/1.4: pri.c pri_internal.h q921.c

[SVN commits to the Digium repositories]

Author: rmudgett
Date: Tue Mar  2 17:47:12 2010
New Revision: 1511

URL: http://svnview.digium.com/svn/libpri?view=rev&rev=1511
Log:
Restore ability to change the Q.921 K value.

The Q.921 rewrite only used value of PRI_TIMER_K right after it was set to
the default.  The Q.921 window size was thus no longer alterable by the
user.

(closes issue #16909)
