you mean the global parameter of registrar module .
modparam("registrar", "max_contacts", 1)This will keep 1 AOR per contact. AOR is address of record which is the combination of user@IP ([email protected]). In my case for every registration the IP address changes with every registration. So, OpenSIPS is considering this a different AOR and is saving multiple contacts. *Thanks & Regards* *Sasmita Panda* *Senior Network Testing and Software Engineer* *3CLogic , ph:07827611765* On Wed, Apr 22, 2026 at 1:12 PM Richard Robson <[email protected]> wrote: > Have you tried to limit the number with max_contacts() parameter ? if you > set the value to 1 it should only keep one AOR per contact.
