There are several ways to get a universally reachable address that other clients can use to call you. The most classical ones will be described here.Using an ILS directoryIf you are registering to an ILS directory like ils.seconix.com, then other users will be able to call you using an URL such as callto:ils.seconix.com/myself@example.com whatever your IP address is.Using a dynamic hostnameYou can also register to a service providing DNS services for dynamic IP's. That way, your machine will always be associated to the registered hostname. This way other users will not need to know your IP address to be able to call you.Using a gatekeeperIf your company is running an H.323 gatekeeper on a public IP, it can be configured to accept calls and redirect them to the correct GnomeMeeting client based on the called URL. For example, if a gatekeeper is installed on example.com and user joe is registered to that gatekeeper, then other users will be able to call joe using the following URL: h323:joe@example.com.Using an ENUM recordYou can register an ENUM record on www.e164.org. That will permit you to associate your real phone number to any valid H.323 URL, and other users will be able to call you using your real phone number. For example, +3210444555 will be directly linked to h323:myhostname.com and other users will be able to call you using h323:3210444555.
