[Spce-user] Hide customer password in Kamailio DB

[Mathys Frédéric]

Hello Daniel,

Could you give me more information about this trigger you use to provision the DB? If a hacker takes control of my SIP server (hope it will not happen...) I don't want him to diffuse the clear text password on the internet.  

Thank you for your help,
Frederic

Hi,
That's work only in you create the user via kamctl command.
We create the entry via a mysql trigger from provisioning database.
As far as I know you should change that trigger command.
