I'm looking at doing something very similar.
I was going to add into Asterisk Realtime an extra field that is a
server identifier. For example to allow multiple asterisk machines
to use the same CDR DB. You would be able to select on the data from
just one of the servers.
Also for example in sip.conf for registration. Have the specific
asterisk server that processes the sip registration put it's
identifier (IP address for example) into a field in the DB also.
That way other asterisk servers sharing the DB would be able to know
what asterisk server a SIP phone is registered to.
Does anybody else think this might be useful?
Where would be the best place to have a server identifier variable?
asterisk.conf? within the sip.conf that applies just to the sip SQL
tables?

We are building asterisk clusters using mysql replication. All the
configuration and cdr data is stored using the res_mysql module.
Replication creates identical servers. Then, the phones register
to each
server using DNS SRV records. If any server goes down, all the phones
registered to that server will register to any of the remaining
servers.
The only downside of this is that all active calls get dropped once
the
server goes down, but users can make and receive new calls
instantaneously.
Another idea is to use Asterisk Realtime so that the mysql
replication will
share registration information between servers, thus eliminating
the need
for the phones to re-register. Has anyone successfully implemented
this or
something similar?

I found many mailing list threads and one wiki webpage with ideas and
questions related to failover and high availability solutions.
Is there any webpage or wiki page that summarizes all these ideas?
What I have found:
- case 1: two identical Asterisk boxes with one acting as hot-
failure backup
http://www.voip-info.org/tiki-index.php?page=Asterisk+failover+case1
- low tech DPDT relay
http://www.voip-info.org/tiki-index.php?page=Asterisk+failover
- VRRPD (KeepAlive daemon)
- Linux-HA and DRBD and heartbeat monitoring
- many mailing list postings with partial ideas
Should I ask the asterisk docs list instead?
