New Revision: 378081

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=378081
Log:
chan_local: Parse dial string consistently.

* Fix local_alloc() unexpected limitation of exten and context length from
a combined length of 80 characters to a normal 80 characters each.

* Made local_alloc() and local_devicestate() parse the same way.
