Instead of doing another DNS query, sip.broadvoice.com is returning more than one IP address, simply keep all of the addresses returned from that initial DNS query, and if a call fails on one, just try the others already in memory. I suppose, if all of those failed, performing another DNS query to see if there are new entries to try would make scenarios where one IP address fails less likely to impact service. The system would have a little more internal redundancy, allowing it to gracefully handle failover to other addresses, making recovery from similar external failures more automated and requiring less manual intervention to restore service. Almost always a good thing for a telco system. From my experience, it isn't that unusual for multiple IP addresses to be provided for VoIP services, or for one of the IP addresses to be down from time to time for maintenance purposes. As I mentioned in a previous message, I'm just getting started with Asterisk. Perhaps something like this is already happening, though it doesn't sound like it based on what I've been reading in this thread.
