[Freeswitch-users] redundant configuration questions

[Sean Devoy]

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
