Hello. I'm new with Kamailio. I have a stored function in a database which accepts `username`, `realm`, `ha2`, `nonce` and `digest_response`. Basing on this and the raw password stored in a database, it calculates inside `ha1` and `digest_reference` to compare with `digest_response` and returns the verdict: passed or not.

This approach gives a high-security level as a benefit. How it can be used with Kamailio? Thanks.
