Hi, I had the intention to route calls to some SRV destinations via dispatcher and to other SRV destinations via DNS lookup and 'use_dns_failover=on'. Currently in a route block using dispatcher two out of three targets within the SRV destination are unavailable (by intention). During my tests to the dispatcher destination I have found that: A) If I have 'use_dns_failover=on' this setting "overrules" the dispatcher routing and the unavailable targets are also tried before DNS failover finds the available target. B) If I have 'use_dns_failover=off' the dispatcher routing logic works as expected and the call is always routed to the only available target directly, making use of the result of the dispatcher OPTIONS pinging. -- So my conclusion is now that you have to choose: Either use dispatcher routing, or use DNS failover based routing. - I'm fine with this, but I just would like to know if my conclusion is correct, or if there is actually a way to use dispacther for some SRV destinations and DNS failover for other SRV destinations.
