New Revision: 196273
URL: http://svn.asterisk.org/svn-view/asterisk?view=rev&rev=196273
Log:
Add callbacks to increase/decrease analog_ss_thread counts from within sig_analog. This is a lot of code to do so little, but should be done this way until the analog_ss_thread in chan_dahdi completely goes away.
