This article describes the TelcoBridges Tdev High Availability feature. The hardware and software are both designed with the following 2 goals in mind:

  1. First and foremost, to recover from a system failure and minimize the system downtime or instability. This is achieved with a fault tolerant and redundancy architecture.
  2. Secondly, to keep active calls open after a fail-over, whenever possible.

Important:Tmedia high availability features are described here
