If you do not have access to credentials on Kamailio, how do you want to authenticate registrations coming every 5min? If you want to reuse the auth headers from the 1-hour based registration, then you create a big security problem, normally nonce is valid very short time to avoid reply and offline brute force attacks.

Note that Kamailio can connect to other databases+tables to fetch username and password, it doesn't have to be "subscriber" style. You can customize table name and column names. For example, it can connect to asterisk realtime database to fetch the password from "secret" column.

I read again the uac doc and didn’t find a way to perform this using the functions that seems to require credentials that I don’t have on the kamailio host.

Is the uac module really designed to perform this operation is that way ?

the uac module does that. You can handle upstream registrations in different

intervals than the ones you receive.
