It's not a problem on server:

AsteriskHA1*CLI> sip show peers
Name/username              Host            Dyn Nat ACL Port     Status
106/106                    192.168.0.67     D   N      5060     OK (6 ms)

on client:

reboot of HA1, HA2 takes 192.168.0.245


AsteriskHA2*CLI> sip show peers
Name/username              Host            Dyn Nat ACL Port     Status
106/106                    192.168.0.67     D   N      5060     OK (4 ms)
sipp                       192.168.1.20         N      6000     UNREACHABLE
2 sip peers [Monitored: 1 online, 1 offline Unmonitored: 0 online, 0

and on client:

CC106*CLI> sip show registry
Host                            Username       Refresh 
State                Reg.Time

so as we can see registration information is shared. In sip.conf I've 
setted up bindaddr=192.168.0.245 (floating IP) to force sip clients 
register to floating IP

Like I show above problem is not on registration side (registration is 
shared with file /var/lib/asterisk/astdb).
