I'm running a voip application, asterisk, that dies if it can't resolve the addresses for its SIP registrations. Importantly there are other connections, PSTN, that work even if the internet connection is down. Also, I want the app to stay alive so that it can reconnect to the SIP servers once the internet comes back up. For whatever reason, asterisk itself will not have a fix for this.
I have unbound working on the machine. I'd like to have unbound serve an address from its cache even if it's beyond the ttl IF it can't refresh the address. In other words, just serve the stale address until it can be refreshed. Any way to do this ? sean
