When a list of endpoints is passed to ecallmgr for bridging (say via a ring group or a user's owned devices), the listing can optionally include failover endpoints to be dialed if a user's normal devices are offline.

When this flag is enabled, the provided SIP endpoints are checked for active registrations; if no SIP endpoints remain after filtering those endpoints missing registrations, the failover endpoint(s) are used instead.

User callflow#

When a user has one or more SIP endpoints and has also configured failover (by setting "call_forward.failover":true plus the call forwarding details), a bridge command will be sent to ecallmgr with the SIP device(s) and the failover endpoint. When ecallmgr goes to build the bridge string for FreeSWITCH, the SIP endpoint statuses will be checked; if all SIP endpoints are missing registrations, the failover endpoint will be used. If any SIP endpoint is registered, the failover endpoint is omitted from the bridge string.

Ring Group callflow#

When KAZOO builds a ring group endpoint list, it resolves all group and user IDs into their owned device IDs. That list of endpoints is then sent to ecallmgr for bridging.

This means that if any SIP device from the resulting endpoint list has an active registration, all failover endpoints will be filtered out and not dialed. So if a user has no online SIP endpoints and has failover configured, their failover endpoint will not ring if any other SIP endpoint in the ring group is actively registered.

"Normal" call forwarded endpoints#

If a user or ring group has "normal" call-forwarded endpoints included, since these endpoints don't maintain a registration (since they typically are forwarded to another DID), then they aren't ever "offline" from KAZOO's perspective. Bear this in mind when failover endpoints aren't ringing when SIP endpoints are unregistered.
