2 PRIs - Failover


I currently have a PRI with a bunch of DIDs operating in site A. We are planning to set up a site B with its own PRI and its own DIDs. I would like to be able to also set up PRI B so it serves as a backup to PRI A.

Here are the options I've thought of:

-. All calls ring PRI A and should it be down they ring PRI B

-. All calls to PRI A ring PRI A and PRI B simultanously. Calls to PRI B only ring in PRI B.

Are these options feasable? Is there another way to set them up?

A few more questions:

-. should any carrier be able to set this up?

-. do both PRIs have to be with the same carrier?
