4 1. Introduction The purpose of this document is to provide clients (and potential clients) with a high level perspective of the approach, framework practices and systems that GSN has developed for establishing and maintaining the levels of solution availability required for delivery of Cloud Contact Centre ( CCC ) services. This document has been prepared specifically for use by: Domain / Enterprise Architects Security Specialists System Integrators IP Networks Design & Build specialists This document assumes the reader has reasonable familiarity with concepts in Telephony, Computer Telephony Integration and Voice over IP. GSN have developed four distinct availability approaches that incorporate best practice designs for the provision of enterprise cloud services, whilst recognising that the balance between cost, availability and functionality is not the same for all customers. Although GSN has capability to support availability approaches other than those listed, these four approaches incorporate the most common and generally the most effective approaches. The following availability types are offered: Availability Type Description Real-Time Return to Operation Drill Frequency 1. High Availability Instant + Zero Loss 2. High Availability Instant Dual PoP Active / Active mirrored In the instance that a customer link fails or a GSN PoP becomes unavailable, failover occurs within a time period where already-in-progress real-time agent & customer interactions are able to continue. Non-real time systems experience near zero data loss with call recording and historic data replicated geographically in (or near) real time. Dual PoP Active / Active replicated In the instance that a customer link fails or a GSN PoP becomes unavailable, failover occurs within a time period where already-in-progress real-time agent & customer interactions are able to continue; however, non-real time systems may be more significantly impacted < 10 Seconds Quarterly < 10 Seconds 6 Monthly 3.

10 3. Disaster Recovery 3.1. Overview The Disaster Recovery option is GSN s based offering for availability and provides an effective mitigation strategy for disasters that may impact a GSN Point of Presence. A disaster is declared when GSN services become unavailable for more than two hours. At this point customers that have the Disaster Recovery availability approach will begin to have systems transferred to the alternate GSN Point of Presence Whilst GSN Disaster Recovery may not suit all businesses, when it is combined with the alternate service recovery options (see Section 7) a powerful and cost effective solution can be provided Impact to Real Time Systems in a Disaster The table below provides an overview of the customer and agent experience in the instance of a disaster. Interaction Type Impact to In-Progress Impact to Post Event Inbound / Outbound Calls Dropped Restore after 4 Hours Web chat Dropped Restore after 4 Hours Delayed Restore after 4 Hours Social Delayed Restore after 4 Hours The table below provides an overview of the service restoration targets in the instance of a critical event that impacts real time Interaction Type Inbound / Outbound Calls Web chat Social Service Restoration Target 1 Hour 1 Hour 1 Hour 1 Hour 3.3.

Impact of Bring Your Own Trunks Where customers BYOT, the trunk provision is excluded from SLA calculations; however, failover can still be readily be achieved by utilising the following approach: From a customer configuration perspective no additional configuration or setup (other than standard BYOT) is required. The SIP Trunk is established to the GSN Service IP Address and this is also the address where RTP is sent. In the instance of failure within the GSN network GSN edge security devices provide stateful failover across geographies and calls in progress can simply continue. 9 GSN Cloud Contact Centre Availability & DR Datasheet Global Speech Networks Commercial in Confidence

15 7. Alternate DR Mitigation Approaches There are multiple application level options available that can significantly reduce the impact of a disaster when utilising the GSN Disaster Recovery option Emergency Messaging Emergency messaging can be applied to specific inbound numbers to provide further information to customers such as an ETA to the outage or alternate contact arrangements. Emergency messaging can be managed through the GSN Management Portal GSN Mobile Connect for Voice GSN Mobile Connect for Voice enables a default call routing and delivery solution that sends contact centre calls to a pre-defined list of mobile phones. The mobile phone list is managed through the GSN Management Portal and can contain up to 30 telephone numbers to which calls will be delivered in a round robin fashion. The solution is activated the GSN Management Portal and does not require any form of mobile data connectivity to function. The solution is an effective response for short duration disasters for small to medium sized contact centres Intelligent Network Overflow Where Toll Free or other Intelligent Network numbers are utilised alternate call routing on No Answer and Busy can be configured to forward inbound calls to alternate destinations including disaster recovery sites or external outsourced call centres GSN Internet Connect for Non Voice Customers using non-voice channels such as and Web Chat can utilise internet based connectivity (rather than dedicated links) to access the GSN CCC from any location. Internet based access is manually activated in the instance of a disaster for nominated customers and solutions GSN Group Voic GSN Group Voic provides a voic box to which callers can be directed if a disaster occurs. The voic is delivered by and can be managed as a workflow for customer return calls from any location with internet access. GSN Group Voic is activated from within the GSN Management Portal. 12 GSN Cloud Contact Centre Availability & DR Datasheet Global Speech Networks Commercial in Confidence
