Thanks Kaufman,

Relying on DB is of course one way to do it, but I thought that there are some 
modules that could be used and are faster, like app_lua but I'm not sure if it 
can be used to select a number randomly from a pool saved in a file.

Regards,

There's functionally two parts to this question:


  1.  How to change a number
  2.  How to select a random number

For selection of the number it's probably easiest to rely on DB lookup. With 
one column as the original number and another column as the possible 
replacement numbers, then just select with an order by random to get the 
replacement number.

As far as changing the number, it can depend on specifically what number you're 
trying to change.  The RURI can be changed just by setting $rU.  Values in the 
To: or From: headers should be changed with the functions from the UAC module 
so that replies can have the original values restored.  For other miscellaneous 
headers like P-Asserted-Identity, just remove the old header and append a new 
one.

Regards,
Kaufman

Hello,

I'm looking to change the A number (from number) to a number selected randomly 
from a pool of existing numbers (hundreds) and then relay the call to a certain 
gateway.

What is the best and more efficient way to do it in kamailio?

Thanks in advance
