Thanks Alex,
Yes I'm aware of that, this is just for testing purposes.
Regards,

You can just modify the domain portion of the RURI, i.e. by manipulating $rd. For example,
$rd = "some.ip"; Then, t_relay().
However, beware that sending the call back to the same gateway from which it came is
likely to cause call loops. Proxies don't create new call legs, they are just part of
the same logical call leg; call leg "A" comes in, and call leg "A"
goes back out, with the same Call-ID, CSeq, etc. If you send the INVITE back to the same
gateway that originated the request, it will likely reject it since it is literally the
same request it itself created.

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,

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.
Cheers,
Henning

Subject: [SR-Users] Randomize calling number Hello, What is the
best way to change the calling number to a random number (based on specific pattern, like
number of digits for example) in an invite packet without using a database.
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.

Ali Taher
