[Freeswitch-users] Random number generation

[Chris Young]

Hello all,

On the wiki, there is an example of using mod_expr to generate a random number:

                <!-- generate random number between 1 and 100 -->
                <action application="set" data="rand_val=${expr(randomize(&x);ceil(random(0,100,&x)))}"/>
                <action application="log" data="INFO Random value is ${rand_val}"/>

This works well the first time but if the same dialplan instructions are executed subsequently, the same number is produced each time.

Is this by design? Is there any other way to seed the random number generator so it will produce different results, as randomize() doesn't seem to be doing quite what I thought it would?

Many thanks,
Chris
