I would install a local copy of MySQL (to the same machine as Asterisk) so 
that it is definitely available, tell Asterisk to write to that, and then set 
up replication to the remote MySQL instance which is sometimes unavailable.

Replication will sort itself out automatically after almost any duration of 

If you are using MySQL, the traditional Master-Slave replication is easy to 
set up and works well.  If you're using MariaDB (which is installed in some 
distributions even when you ask for MySQL) then the new method of replication 
is Galera, although standard Master-Slave is still fully supported.



If my advice was worth anything, I wouldn't just give it away.
