[OpenSIPS-Users] SIP UAs Authentication based on a combination of username, password and IP address of the UA

[Bogdan-Andrei Iancu]

Hi Sujeev,

You to first do standard digest authentication of the user (using the 
proxy_auth() function) - to also check the IP, add a new column in 
subscriber table (to keep the IP address) and load that column (during 
digest auth) using the load_credentials (see 
http://www.opensips.org/html/docs/modules/1.6.x/auth_db.html#id228201)...

So, once the digent auth was successfully validated, you will have the 
provisioned IP loaded into a script variable, so you can easyly check it 
against $si (source IP of the message).

Regards,
Bogdan
