[Freeswitch-users] NOT in dialplan expression

[Tihomir Culjaga]

it depends of what you are trying to acheave.... one approach is with regex

check this: http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_regex

you can set a different variable and have it true or false ... than you can
compare for false state...


well .. it is up to you ...
