Not quite. > Internet calling does not need to be enabled if using sipXbridge, it > does it natively. The Internet Calling checkbox controls whether or not you can route to an arbitrary SIP URL somewhere on the internet. Since that's what ISN dialing provides a telephone-keypad way to do, you do need to enable Internet Calling. > sipXbridge does ITSP trunking True, but it can also be used to route to unconfigured targets if you enable Internet Calling. > sipXbridge supports remote workers (Nat traversal, via media relay) Nope - remote workers connect directly to the sipXproxy. The media relay is shared between the bridge and the proxy. ISN dialing (see http://freenum.org/) provides a way for the registrar to translate a dial string like 123*5678 into a sip url [email protected]. The actual routing of the request is then done using normal SIP rules. If you're not putting your sipXecs system directly on the public Internet, then you need to route the call through an SBC to allow the traffic in and out. You can use sipXbridge as that SBC. _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-users sipXecs IP PBX -- http://www.sipfoundry.org/
