[SR-Users] Re: Randomize calling number

Hi Henning, I used the uac_replace_from() function to replace the fU, but the value is still the same when i printed it using xlog. I also dont know how to send the invite back to the switch. What function to use? Thanks, Sent from my iPhone On Jul 6, 2023, at 5:31 PM, Henning Westerholt &lt;hw(a)gilawa.com&gt; wrote:  Hello, Not 100% sure if I understood your question correctly. There are probably many ways. One option is to use the $RANDOM pseudo-variable that can generate (pseudo-)random numbers. You can get it to the pattern you like with some script operations in the cfg. Just rewrite the request URI user of the INVITE in Kamailio to the new generated number and send it out again.

So the scenario is : * receive an invite packet from certain source * change the calling number * send back the invite packet including the new calling number to the original source.
