Last week I had a problem with my VFX and did not even know it.  My ATA had somehow reset the voice section to defaults and thus lost the provisioning rule.  Found it out only on Saturday!

The suggestion is a facility whereby we can register an e-mail address to get notified if our ATA had not registered for more than a pre-set period.  It is supposed to register every 3 minutes, but it can happen that one had to restart your modem/router, so perhaps a time-out of 10 minutes?  Or a configurable time-out?  Also more than one notification e-mail address would be handy, say to send to home and work.
