I have a client that has two sites that are in an active, passive configuration right now. They want to make it an active/active configuration and use the other one as a back-up. They have a single gateway at each location that does transcoding and local and LD.
I want to load balance between the two sites using device pools, however I want to make it so the gateways are fully redundant as well. If the one in site A fails then calls are routed out of the one in site B and the other way around.
Does anyone have any good articles or solutions here?
