Note
Branch Office Resiliency
If you sign into the phone using Onprem account, you can use branch office resiliency feature.
Current Online environment does not support this feature.
Branch office resiliency is critical for multi-site deployments of Skype for Business where the
control servers are located at a central site or data center. It allows branch site users to continue
to have Enterprise Voice service and voice mail (if voice mail rerouting settings are configured)
when the branch site loses the connection to the central site.
When the WAN connection between the branch site and central site is unavailable, the phone
goes into resiliency mode:
Branch site user on the phone stays signed in with an indication of “Limited service due to
outage”.
Call between branch site users is established successfully with 2-way audio.
Conference between branch site users can be established successfully.
The call history cannot get modified. (Already downloaded call log entries will not be
deleted).
Multicast RTP is one way only from the sender to the multicast address(es) (receiver). For
outgoing RTP multicasts, all other existing calls on the phone will be placed on hold.
