[Users] Difference between Alias and Listen

Ahh, this links back to your previous message and adds a little light. IMO, it is not good practice to put domain names for listen. I would only list IP addresses, and that list should be relatively small because you don't need the IP address to distinguish between clients. For example, I just have one listen command in my config. For a critical service like this, either hard-coding in the IP addresses to listen on, or be willing to listen on all attached interfaces, should be Standard Operating Procedure (I vote for the former). Don't put the port in there. Just list the domains that the server is responsible for. I think this should be explained more fully by someone in the know... For example, if you are using the "domain" module then would we expect to never have to use "uri==myself" and not have to list aliases? (using is_uri_host_local() instead) An earlier hint from someone here to me said something like "openser doesn't know that the message is directed at itself" and I wonder how the use of the "domain" module affects things *inside* the openser core. And then there is the environment variable SIP_DOMAIN... does that have any bearing on the function of openser or is it just used for the supporting scripts (openserctl). What is the role of this variable in a multi-domain setting? -mark
