    <p><tt>No, I meant "write-through", since your platform seems to

        have the requirement of<br>

        "guaranteed registrations", which seems completely reasonable. 

        Using "write-back" can be a<br>

        double-edged sword because you get the WRITE performance, but

        unless you have an<br>

        active-backup setup which allows you to failover and only then

        do your maintenance<br>

        restarts, some portion of your phones may become unavailable for

        1h after you restart<br>

        your OpenSIPS because the "write-back" registration did not get

        a chance to be<br>

        persisted to DB.</tt></p>
