VOIP / Asterisk Fail-Over Possibilities?
Posted on 2009-05-20
I am wondering about fail-over capability with VOIP, in an asterisk environment and SIP peers or UA devices, across the WAN or internet.
I want to eventually have fail-over in case the main internet connection that my asterisk server is on, goes down.
I was hoping to do this through some sort of dynamic DNS with my domain through Godaddy but apparently they do not support dynamic DNS.
I have my domain setup through godaddy, and I created an A record for voip.mydomain.com, pointed it to my asterisk WAN IP and thought about using that address in my UA or sip peers, instead of the IP address.
Is there a way to have a solid fail-over with sip peers in an asterisk environment? I think the solution has something to do with DNS SRV, but I am not too familiar with how it works. Does using DNS SRV cause more problems with things like, 1 way audio etc?
