My way:

from original kamailio.cfg in global parameters:

#!define WITH_MYSQL
#!define WITH_USRLOCDB
#!define WITH_AUTH

then:

auto_aliases=no

one entry for each domain/subdomain, example:

alias="sip1.kamailio.org"
alias="sip2.kamailio.org"

add the user using IP, example:

kamctl add 100@1.2.3.4 password

You have 3 options:

1) Create the 100 user in all the domains with the same password.
2) Disable domain in auth_check
3) On the routing logic, when you detect your 100 user, do an auth without domain chekin (kind of option 2 but only for specific users)

Subject: Re: [SR-Users] Accept IP/Domain Register

I think my question not is clear.

I'd like create/configure, for example, user 100 and this user can 
register with kamailio using Kamailio IP or Kamailio associated Domains; 
this using digest authentication.

Yes. There is no rule that you have to issue a digest authentication challenge in response to registrations.

You can handle them like any other request, including validating the source IP against an IP ACL (e.g. allow_trusted(), or hard-coded like if(src_ip == 1.2.3.4)).

Hello,

maybe is a very basic question; How Kamailio can accept any kind of register, over IP or domains.

Example, accept authenticate REGISTER from ip 1.2.3.4 or sip.domain.org or sip1.domain.org, domains associated with ip 1.2.3.4

Thank you in advance.

Regards
