This page describes the TelcoBridges VoIP Gateway high availability features. TelcoBridges' products are designed with the following two goals in mind:

1. Recover from a system failure and minimize the system down-time and network instability, as much as possible. This is achieved with fault tolerance and redundancy designed into the very architecture of the product.
2. Keep active calls open after a fail-over, whenever possible.
