HI, is there a difference in fail over for a bridge from this:

<action application="bridge" data="sofia/gateway/primary/dialstring|sofia/gateway/secondary/dialstring"/>

Or just adding to bridges?

<action application="set" data="continue_on_fail=true"/>

<action application="bridge" data="sofia/gateway/primary/dialstring "/>

<action application="bridge" data="sofia/gateway/secondary/dialstring"/>

What is the best way for failover?
