OK I just had a thought about location based DNS SRV that I wish to share with the members of this list in hopes of sparking discussion. A while back, when I actually implemented a redundant setup, I set the DNS server to have "views" ( http://www.oreillynet.com/pub/a/oreilly/networking/news/views_0501.html ) in that certain subnets would see the same DNS records but with different SRV priorities for different servers.
The big advantage to this is that I could give the local sipX redundant sipX proxy a higher priority on that subnet than the core sipX server so in the event of a severed connection, extensions could still call each other and make emergency calls without needing to use a separate survivability proxy and without a drop in service. This is also useful for locations that have a large distance between them so call signaling stays local whenever possible. The disadvantage is that manual configuration is necessary and DNS changes to one location's zone view require changes in all other zone views as well. My question is has anyone (other than me) ever attempted this (it worked, BTW), and what the developers think of implementing a frontend into sipXconfig to make implementing this type of setup easy, or if it would be a waste of time/resources? Also, is there a limit to the number of redundant proxies that can be configured? Last I heard it was 3 but I don't remember if that was a technical limitation or just an artificial one. Thanks. _______________________________________________ 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/
