cmd Math is deprecated in Asterisk 1.2. use func Math insteadSynopsis
math(returnvar,operation,number)Description
Adds Sum, Multiply, Divide, Subtract, Modulus, GT, LT, GTE, LTE, EQ functionsAll functions follow the same basic pattern for parameters:
- returnvar: the name of the return variable
- operation: the operation
- number: the second number
Each action is performed as
Action param1 on param2
eg:
Action = Divide
Param1 = 10
Param2 = 2
Results in
Divide 10 by 2
Example
Example dialplan:exten => 11099,1,Math(RV,1+20)
