Hi Rodrigo,
To make things simpler to explain : when you use advertised_address,
basically you add a new SIP domain to your server (the external IP you
are advertising). In a static setup, you can do the trick by using the
alias global param (to add a new SIP domain to be handled by OpenSIPS).
If you want to handle SIP domains in a dynamic way, use the domain module.
So, even from users perspective you have a single SIP domain, because of
the advertise you actually do create a new SIP domain you need to handle
(recognize) in script.

Hi Bogdan-Andrei.
I have just studied the Domain Module. But I still wasn't able to
visualize how it can help me.
According to the documentation: "Domain module implements checks that
based on domain table determine if a host part of an URI is “local” or
not. A “local” domain is one that the proxy is responsible for. "
However, in my project there will be always only one proxy and only
one domain. Every sip client will be part of the same unique domain
and the unique proxy must be responsible for every message it
receives. So, the proxy doesn't have to check if a host part of an URI
is “local” or not. For my project, it must be always considered as
local. In this case, my proxy have to handle every message as
responsible for it.
So, I have the following doubts:
1 - If I use Domain module and just put that unique domain in the
domain table, will it be enough to make OpenSIPS handle every message
as being responsible for it? That is, will OpenSIPS automatically
become responsible for messages with host part of an URI equals to
domain in database?
2 - If the answer for (1) is no (and I guess so), is there a way to
force OpenSIPS handle ACK messages as being responsible for it? ( I
have cases when RR header field has the proxy's domain, which
translate to a public IP and it makes the OpenSIPS consider itself not
responsible for the ACK messages. Just when RR has a local IP the
OpenSIPS considers itself as responsible.).
3 - If the answer for (2) is no, should I change the Route header
fields of ACK messages (maybe removing that one with public address),
to force OpenSIPS be responsible for the messages?
4 - If the answer for (3) is no, should the client invert the order of
RR header fields, so that the proxy will consider first the one with
local address and then will become responsible for it? (I have cases
when RR has 2 addresses, one local and one public)
Until now, the workaround was the use of Alias, as you tell me to do.
But, as long as I can't continue using a static Alias, I have to
abandon this.
Sorry the big message.
Any hint will be very helpful!
Best regards.

Hi Rodrigo,
Use the domain module to list aliases via DB ; and in your script,
where you have the "myself" checks use one of the functions from
domain module:
is_from_local() or is uri_host_local()
See:

Dear OpenSIPS-users,
I have used the global parameter Alias successful. The same for
advertised_address.
Now, I have to configure these values at execution time. Such values
will be determined just after starting my system. So, I need a way to
configure these values in a dynamic way.
Then, I will use the core function set_advertised_address.
But, I did not find a core function to set the Alias at execution time?
Is there a way to set Alias at execution time? Is there a function
for that or can I set Alias with a database query. Ex: Alias = select
from....
Any hint will be very helpful!
