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.
