Branch Office Resiliency

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 voicemail (if voicemail rerouting settings are configured) when the branch
site loses the connection to the central site. In this situation, your phone will prompt "Limited service due to
outage", and the presence icon is displayed as Unknown. When the WAN connection between the branch
site and central site becomes available, the phone comes out of resiliency mode automatically. Notification
of resiliency is automatically dismissed, and you can use phone features as normal.
Note: If you sign into the phone using On-Premises account, you can use branch office resiliency
feature. Current Online environment does not support this feature.
