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.

Regards,

Ali Taher
