Incorrect :) IAX2 most definitely does support regcontext.
Also, I think what he means is the phone specific information must be
exactly the same from system to system or the failover won't be as
seamless as you expect. A lot of phones support some sort of SRV
records, so in the event of a failure, the phones will automatically
find the next available server. The other option there is to set up an
HA environment so the failover is even transparent to the phones, they
just start talking to the new IP address immediately.
Another thought, in any failover situation, if you have any sort of
automated failover, you must make sure phones that need specific
features fail to the same server (i.e. hinting and such) as those
features don't work cross server.

There I go spreading mis-information again. :)
Thanks Aaron for clearing up the IAX2 regcontext question. That is good to know.
In the DUNDi scenario, are there any other features that would be
affected or become unavailable in the event of a failure?
It seems like normal call processing would continue once the client
re-registered to a different box, but I haven't tried it yet.
I assume one could use DNS-Round-Robin to load balance registrations
between the boxes in the cluster, then pull the failed box out of DNS
to prevent registration attempts while the box is dead. Is there a
better way to do this ???
