Redundancy (was Re: [A*UG] Installfest Distro and Background)

[Brett Nemeroff]

Gil,
I'd be interested hearing from you and others in the group about how
you've implemented redundant servers.

I've implemented redundancy using UCARP and a daemon which tests the SIP
channel using sipsak. I find that sometimes the sip channel driver dies in
asterisk but IP isn't dead so UCARP doesn't take over.

I'm not real happy with this setup. It's complicated and difficult to manage.

What have you implemented?
