I am referring to the <global-address> and <external address> from <bridge-configuration> located in the sipx bridge configuration file (sipxbridge.xml)
Without getting too deep into the reasons and problems; I need to have two different public IP addresses in this particular sipx deployment. One standard public IP for sipx in general and a different one just for one of the sipx bridges. The reason for this is that the main voice provider for this customer is deploying SIP trunks over physical private network without authentication and they demand that the sipx has a private IP address in a particular given subnet and the invites from field must contain this address in order for SIP trunk to work. The only way I can get this SIP trunk to work is if I setup this private IP address instead of the sipx public IP address. But this messes up a bunch of other things (which I can get around with complicated routing, but I would rather not..) So I plan to change the public IP address just for one of the sipx bridges (there are two sipx bridges with multiple SIP trunks from multiple providers). I intend to do this manually through changing the sipxbridge.xml configuration file. For this reason I ask what is the <global-address> for and what is the <external address> for in the sipx bridge configuration file? 2011/1/8 Tony Graziano <[email protected]> > I don't follow the terminology you are using. > > Public address is used in two places.
