The $random gives an integer value, so max length is 10. Actually, vars in config file can be either integer or string. If you want a larger length you can build it as tring from two other random values. Like:

$var(r1) = $RANDOM;
$var(r2) = $RANDOM;

$var(largerandom) = "" + $var(r1) + $var(r2);

Note the empty string "" used as first element in the right side of the above assignment -- that will make the result to be string, otherwise will be another int, rounded after overflow.

To get string from concatenating two integers you can use alternatives as pv_printf(...) or $_s(...).

Daniel,

I tried using $RANDOM. It is always giving a random value between 9 digits to 10 digits  How can I get a random value between 10 digits to 13 digits.

Thanks Daniel,

I will try app_lua as you said this being faster compared to $RANDOM.

I didn't say that app_lua is faster than $RANDOM -- what I said is that
app_lua is also fast.

Now if I want to modify the caller id number (ANI) , can I assign the newly generated number to the variable $fU?

Yes, look also at uac module for functions to replace From URI.

Cheers,
Daniel

Hello,

besides $RANDOM from cfgutils as pointed already, you can use an
embedded interpreter (e.g., app_lua is really fast).

If you need some unique values, but not only numbers, see uuid module.

Cheers,
Daniel

Hi,

How can I generate a random number say of length 10-14 in Kamailio. Can I use cfgutils for this. Please advise
