Hi Henning,
Is there a way to change From URI user part without touching the domain ? As I can see in
uac_replace_from there is an option to either change the display part or the whole URI
part.

Hello,
ah, you want to change the From URI user. Yes, uac_replace_from is a common approach for
that.
This function will change the From URI when you send out the message, you will not see it
with a xlog in the cfg.

Regarding sending out the SIP message, a common approach is to use rewrite the request URI
to the new destination and then use “t_relay” to send it.
Cheers,
Henning

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 :
1. receive an invite packet from certain source
2. change the calling number
3. send back the invite packet including the new calling number to the original
source.
Regards,
Ali Taher
