I did, but I don't see how to limit the range:

From the docs: Returns a random value from the [0 - 2^31) range.

Is there a way to limit the range from 1-100 for example? Or maybe the way is to use $RANDOM and just rely on the first/last 2 digits (essentially a 00-99 range)?

Hello,

 

what about just using this PV: https://kamailio.org/docs/modules/5.5.x/modules/cfgutils.html#idm438

Subject: [SR-Users] Tips on picking random element from a list

 

Hi Everyone, 

 

I have to implement a flow where outbound calls get their caller-id set with a random number from a pool.

 

I've been looking around and, as most of the time, there are tons of ways to implement something like this... This is a simple implementation, the number pool is fixed and will not change (so I could have it hard-coded in the config if required).

 

My initial approach was:

 

1- Try to keep it simple, with no dependencies, and all done in the config script.

2- If #1 is "ugly", then I'd probably go with some inline code using python/lua/etc

3- If #2 is "ugly", then I'd go with having the info in a DB and just run a query

 

I think #2 and #3 might be overkill for something so "simple" but I haven't had to work too much with randomness in Kamailio, so any tips/suggestions on where to store the number list and how to pick one randomly would be awesome!

 

Thanks!!

Joel.
