I'm a newby to ISDN. Can someone tell me if this will work?
I have two 2651XM voice gateways. Each gateway has a single ISDN circuit. The phone company has the 2 D channels setup as a shared active/failover configuration. The circuit is B8ZF, ESF, NI2. Is this going to work?
Unfortunately, this isn't supported to my knowledge. You can turn up lots of documentation on 'ISDN NFAS' on CCO, which is the technology used to control B channels on multiple PRIs from one D channel, and to support an alternate backup D channel if the first one dies. However, this only works within one gateway, not between multiple gateways.
This sort of thing can be done using SS7 signaling external to both gateways, but this is a rare configuration and usually limited to service providers. It's really unlikely that you can do this.
You could move them both to one gateway and make this work. However, if this is to be configured with CallManager, note that CallManager has no idea how to handle NFAS PRIs so you'll need to use H.323 signaling instead of MGCP. If you're already planning to use H.323 or another technology where the router handles all q.931 signaling, you're fine.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
