[SR-Users] Re: Randomize calling number

[Henning Westerholt]

Hello Ali,

you can just build the new From URI the way you like it, e.g.:

uac_replace_from("$var(from_user)", sip:$var(from_user)@$fd);

Cheers,

Henning

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.

Regards,

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.
https://www.kamailio.org/wikidocs/tutorials/faq/main/#why-changes-made-to-headers-or-body-are-not-visible-immediately

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,

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.

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.

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.
