New Revision: 131868

URL: http://svn.digium.com/view/asterisk?view=rev&rev=131868
Log:
Add configuration option to chan_dahdi.conf to allow buffering policy and number of buffers to be configured per channel. Syntax:

buffers=<num of buffers>,<policy>

Where the number of buffers is some non-negative integer and the policy is either "full", "half", or "immediate".
