Greeting Everyone,
I hit a bit of a road block in my design. I'm using SRV for proxy failover on the customer side, but I'm wondering if third-party PSTN providers will support SRV when delivering calls to my SERs. I want to make sure if the PSTN provider cannot reach one SER they try another. I've only talked to a couple providers so far, and it seems they want to just send traffic to an IP address. Is this the norm? Is HA with heartbeat and a single IP the only solution here?
Thanks! - Daryl
