-Mathematical dialplan function
-
-Yeah, I thought it was a little insane too..
-
-adds:
-
-Sum, Multiply, Divide, Subtract, Modulus, GT, LT, GTE, LTE, EQ functions to Asterisk
-
-All functions follow the same basic pattern for parameters:
-
-parameter 1 = the math expression
-parameter 2 = the type of result
-
-Perform calculation on number 1 to number 2. Valid ops are:
- +,-,/,*,%,<,>,>=,<=,==
-and behave as their C equivalents.
-
-<type_of_result> - wanted type of result:
- f, float - float(default)
- i, int - integer,
- h, hex - hex,
- c, char - char
-
-Each math expression is performed as
-
- Action param1 on param2
-
-eg:
-
- Action = Divide
- Param1 = 10
- Param2 = 2
-
-Results in
-
- Divide 10 by 2
-
-
-Example dialplan:
