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!
