[Asterisk-Users] DUNDi in 1.2.7.1

[Douglas Garstang]

DUNDi isn't really redundant. If any one server goes down, all registrations will be lost for phones registered with that server. This will remain until the phons re-register with another Asterisk box. Better make your registration expiry period reeeealy low. Most people won't accept waiting 30,15,10 min to be able to receive calls again.

We're seeing issues with Asterisk failover and DUNDi too. I made a post yesterday, but no one has replied. It really looks like a bug. When the asterisk box that a phone is registered with goes away, and the phone tries to immediately make calls through a second Asterisk box, asterisk keeps sending 407 proxy auth messages to the phone over and over again, even after the phone sends credentials. REALLY screwy. About 5min later, it starts to magically work with no manual intervention.
