hi guys, <include> <extension name="welcome_ivr"> <condition field="destination_number" expression="^samira$"> <action application="lua" data="welcome.lua"/> </condition> </extension> </include> i have created lua script like this: /usr/local/freeswitch/script/welcome.lua #!/usr/bin/lua local sf = string.format function binary_op(a, b, callback) return callback(a, b); end function plus(a, b) return a + b end function minus(a, b) return a - b end function times(a, b) return a * b end print(sf("Plus : %d", binary_op(5, 5, plus))); print(sf("Minus: %d", binary_op(5, 5, minus))); print(sf("Times: %d", binary_op(5, 5, times))); the result of running that is 3 number, but how can i get the 3 number in dialplan of freeswitch so that use the result of this number on it ? thanks so much
