    In a large deployment with an offsite PBX, we'd use multiple on-prem SBCs.

    Rather than having to specify the IP of the specific SBC each extension will use, it'd be nice if we could set up a round robin DNS (i.e., sbc.company.local) to automatically load balance across the multiple SBCs. Benefit: automatic failover if an SBC is down; not having to manually determine which SBC a specific extension should use, etc.

    It's my understanding that this is currently unsupported.

    Thanks!

    While in theory your idea will work, but DNS load balancing is one of the most primitive forms of load balancing. Clients will still attempt to query a SBC that is offline because DNS tells them to do so. You would need a mechanism to remove the down'ed IP from the DNS address. For this to work perfectly as you describe you would want a hardware load balancer.

    Good point on the load balancer. that's not difficult.
