New Revision: 228691
URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=228691
Log:
Created standard location to add options to chan_dahdi for ISDN dialing.
Dial(DAHDI/g1[/extension[/options]])
Current options:
K(<keypad_digits>)
R Reverse charging indication (Collect calls)
The earlier Dial(DAHDI/g1[/K<keypad_digits>][/extension] format was
variable and did not allow for the easy addition of more options.
The earlier 'C' prefix character for reverse charge indiation would
conflict with the a-d DTMF digits if ISDN uses them.
