Enabling Webex Calling (VAR Channel) v1.5

Date
June 2020

Overview

Cisco Webex

Cisco® Webex is an app-centric cloud-based service that provides a complete collaboration suite for teams to create, meet, message, call, whiteboard, and share, regardless of whether they’re together or apart; in one continuous workstream before, during, and after meetings. It’s built to make teams work seamlessly. It’s a simple, secure, complete, and open service that enables people to work better.

Cisco Webex Calling

Cisco Webex® Calling is a collaboration offering that provides multi-tenant cloud-based alternative to on-premise PBX phone service. It is branded by Cisco and provisioned by partner value-added resellers (VARs). VARs are not regulated service providers and cannot provide PSTN service. PSTN service must be leveraged through an enterprise local gateway deployment or Cloud Connected PSTN provider. Webex® Calling also provides service assurance through media quality metrics.

Layer 2 Box-to-Box Redundancy

Layer 2 Box-to-box redundancy uses the Redundancy Group (RG) Infrastructure protocol to form an Active/Standby pair of routers. The Active/Standby pair share the same virtual IP address (VIP) across interfaces and continually exchange status messages. CUBE session information is check-pointed across the Active/Standby pair of routers enabling the Standby router to take over immediately all CUBE call processing responsibilities if the Active router should go out of service for planned or unplanned reasons, preserving both SIP signaling and media. RG Infrastructure protocol monitors both the inside and outside interfaces – if any interface goes down, the whole device is considered down, the Standby device becomes active and takes over the responsibilities of the Active router.

Starting IOS-XE 16.12.2, the Local Gateway for Cisco Webex Calling will be able to utilize CUBE HA for call preservation in an all IP deployment. This redundancy option for call preservation in Cisco Webex Calling is supported on ISR 4K and vCUBE (CUBE on CSR1000v) only.
