Disaster Recovery and Survivability - Lync

DRS provides a sophisticated, high-availability platform delivering an unprecedented level of survivability to Microsoft Lync and Skype for Business Server solutions deployed at enterprise locations worldwide.

Disaster Recovery Services are an integrated suite of cloud-based call control and unified communications tools designed to allow an enterprise to define the policies and procedures by which voice traffic will be handled during any form of outage.

Unmatched Survivability

DRS works seamlessly with MaxxConnect to provide survivability from any type of interruption—from minor, temporary service disruptions such as carrier issues, circuit or power outages, LAN or WAN failures, to full-scale catastrophic events or natural disasters. DRS is also useful when network or system maintenance is required, preventing unnecessary downtime. With DRS, enterprises have flexible options for emergency routing of main numbers. Calls can be delivered to alternate office locations, third-party answering services, or directly to individual home or mobile phones. Calls can also be directed to automated attendant menus for caller-selectable options, emergency notification greetings indicating a temporary out-of-service condition, or to off-site voicemail for follow up when working conditions are restored. Calls to a user’s individual extension or direct inward dial (DID) number can be forwarded to a user’s mobile phone, home phone, or sent to voicemail. Users are notified of new messages via email to allow for rapid follow up response.

Web–based Control

The DRS interface provides customers access to create and control their enterprise disaster recovery plan for inbound voice services and ensure that their calls are routed to alternate destinations should their Microsoft platform become unreachable. Using the DRS interface, customers can create action groups to establish alternate call route plans for inbound primary company numbers and individual lines. With a number of flexible options, action groups can be configured to deliver calls to auto attendants, remote backup sites, home phone numbers, mobile phone numbers or voicemail. DRS also features Active Directory synchronization, which associates individual users’ mobile phone numbers with emergency routes for their DIDs. This simplifies the disaster recovery planning process and reduces manual entry errors.
