Redundancy - Is the current call lost during failover

[Carlaan]

I am looking to find out if we have a redundant Active/Active configuration, if the call that is currently in progress stays connected during a fail over.

Hi Carlaan

Do you mean if the call will drop/go silent or do you mean if the failover server will continue the call?

 

[Carlaan]

Both .. We are looking at what options are available to not lose a current caller that is already connected.

That would not be possible. The provider established an audio call with the primary PBX that went offline.

The secondary PBX comes online and registers the trunk to pick up the next incoming call, but the previous one is lost.

A provider that supports timers will also detect that the primary PBX is down, and should drop the call

I think you need a high availability VM Cluster machine to maintain a call across a failover event, not that it has been tested of course but theoretically that's possible. In this case you are not using 3CX Failover, but VM cluster failover

Thank you for the update .. I know a few options out their were the active call stays active even during a failure. It looks like once the connection is established the RTP stream goes directly from the caller to the phone or softfone.

The RTP stream normally remains on the PBX which streams it to the extension (especially when you enable recordings or PBX Delivers Audio option)

Ideally you would not want the stream to be established from the phone to the provider directly, for a number of reasons that can affect security, recordings, firewall considerations, compatibility and features that might stop working.
