Hi, Is there a way to ensure single-registration per user-agent for a user, which overwrites previous registration ? Or is there a way to limit the number of registrations per user, but overwriting the earliest registration for each new one ? Thanks, Reda

Hello, From the registrar module documentation http://kamailio.org/docs/modules/stable/modules_k/registrar.html#id2494545 3.12. max_contacts (integer) The parameter can be used to limit the number of contacts per AOR (Address of Record) in the user location database. Value 0 disables the check. This parameter can be modified via ser config framework. Default value is 0. But this will not overwrite the previous contact AFAIK. Marius

Thanks, Reda

For one contact per user, use save() with flags parameter (value 4): http://kamailio.org/docs/modules/stable/modules_k/registrar.html#id2497967 Cheers, Daniel

Thank you all, but I already know the above params / functions. They don't fulfill my need. I still need multiple registrations per subscriber, but either one registration per user agent, or new registrations overwriting earliest ones. It seems I can't do that using usrloc or registrar modules for that. Reda On Fri, Mar 2, 2012 at 13:16, Daniel-Constantin Mierla <daniel(a)kamailio.org>wrote;wrote:

you can use it for one registration per user agent, why you say you don't? Nobody stops you using save("location") or save("location", "0x4") based on user agent id, in the same config file. For removing the oldest contact, you will need a bit of coding, or, if you do db only mode, you can do a sql query to remove the oldest record. Cheers, Daniel

I think I didn't define well my need. Or I miss something in my comprehension of the modules/function. I need one registration per subscriber and user agent combination. If a new registration comes for the same combination, it should replace the old one. save("location") doesn't replace the old registration. and save("location", 0x04) doesn't take into account the user agent. I think I should do it manually... Reda On Sat, Mar 3, 2012 at 12:20, Daniel-Constantin Mierla <miconda(a)gmail.com>wrote;wrote:

You can fetch all contacts in the config and check each record there based on your own rules, then do save or reject registration - an example to start from is here: * http://kamailio.org/docs/modules/stable/modules_k/registrar.html#id2498441 Cheers, Daniel
