Any Sonicwall gurus here?
In one of our offices, we have a Sonicwall TZ 210 with EnhancedOS. They currently have 2 internet connections, a fast 25/5 Comcast Cable, and a slow 5/1 SBC DSL.
The failover and failback to Primary WAN work properly. However, they are on a VoIP system for telephones, so when the Primary WAN comes back up, it fails back, disconnecting the phone call.
Naturally, the solution is to disable the preemption to fail-back. However, we would like to keep them on the Cable as much as possible, and checking the status multiple times a day is simply not feasible (21 offices and 280 users with real problems).
Is there a way to force an email alert when it fails over, and another when it detects the Primary WAN is restored so we can gracefully move them back once they're off the phones without disconnecting their calls?
Chaos reigns within. Reflect, repent, and reboot. Order shall return.
