Redundancy & High Availability

(Click here for ProSBC High Availability and 1+1)

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.

TelcoBridges High Availability and Redundancy

TelcoBridges high availability and redundancy is comprised of a collection of features. These features enable customers to add as many HA and redundancy fdeatures to their systems as required.
