To me, that device represents a single point of failure, so I'm not sure what sort of redundancy that gets you. Also, you still sync between your two servers, so that device won't solve all your problems.

I'm going to do a talk for TAUG on how to use Sangoma's TxTristate mode and heartbeat to create a hot-standby system, where you don't need any external hardware.

It's just an overview, and heartbeat requires a fair bit of Linux knowhow. But still, it's do-able, and the only single point of failure then becomes the carrier equipment.

  And no a human hand is not an option :-)
