[OpenSIPS-Users] Is there some way to set Alias at execution time (dinamically)?

[Bogdan-Andrei Iancu]

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.
