We can simply check the callerID using the php function substr (http://php.net/manual/en/function.substr.php) in a MATH block and check the result with a GOTOIF block

For esampleexample, the callerId is 0123456789.

The substr function result will be 012 (first 3 digit) and it is saved into the RESULT variable.

In the GOTOIF block just check the RESULT variable.
