[FAQ] Improved OpenSip Registration Fail-over Support

[SteffenBaierUK]

Traditionally we support multiple methods of failover.

A method described  => here <= is called Configure Fault Tolerance and can be used for all Phones but the document only describes this for SoundStations and the Trio.

A Discussion about this can be found => here <=

Since UC Software 5.5.2 the Polycom Trio supports up to three registrations which the Phone can failover once the main server goes down.

This can for example be used with a Cisco Call Manager as described => here <=

The method described below is not the same as in the Engineering Advisory 66546 aka the Configuring Optional Re-Registration on Failover Behavior => here <=

NOTE: This feature is currently only supported on Polycom Trio’s

The Failover to another server can take up to 30 Seconds and 60 Seconds to re-register to the original first server.
