[FAQ] Improved OpenSip Registration Fail-over Support

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.
