Yes, you need to do more research into SRV records. Let the clients use their local dns servers, and setup backup routes before hand. Any outage you were to hit wouldn't require you to make DNS changes.

Hi All,
I haven’t been able to search and find an answer or suggestion to this specific redundant server question. Sorry if it has been answered and I did not see it.
My VOIP Provider allows for multiple endpoints by priority (aka primary and backup FS Servers). This works fine for getting inbound calls routed to my backup FS Server when Synapse Global is searching for the cause of my outage for 3 hours!!! However, none of the users phones are registered to this server.
For my most demanding customer, I can route to his answering service on the PSTN. But, how do I get the phones to switch to the backup server and get on with life?
Here are the ideas I have had so far. At least on my Linksys and Cisco phones and ATAs, I can specify DNS servers. Setting the PHONES DNS server to MY DNS server, I can eliminate the delay in changing a DNS Name/ Address mapping required for timeout and propagation. Changing DNS entries is thus immediate for the phones. Then we just have the clients ALL reboot their phones.
Of course I realize this make my DNS server a single point of failure!
Is there a cleaner approach? I have read up on SRV and it is clear as MUD. Do I just have to learn more about it?
Thanks,
Sean
