[zaptel-commits] kpfleming: branch kpfleming/dtmf-twister r3489 - /team/kpfleming/dtmf-twister/

[SVN commits to the Zaptel project]

Author: kpfleming
Date: Fri Dec 14 17:36:20 2007
New Revision: 3489

URL: http://svn.digium.com/view/zaptel?view=rev&rev=3489
Log:
store the global dial parameters in a structure intended for that purpose, instead of trying to just store/retrieve them from a default zone's DTMF/MF tones (which may not exist)
