Understanding the Problem

ABSA Group's issues were centred around its outdated communication and contact centre systems, which were inflexible, expensive to maintain, and not mobile-friendly. These on-premise systems hindered its ability to adapt to changing business needs, expand efficiently, and provide seamless customer experiences. It was susceptible to service disruptions and did not effectively support remote work. Below are some critical challenges addressed by implementing Teams Phone Systems alongside Anywhere365 Unified Contact Center solution

Manual Identification and Verification of Customers

In the old contact centre system, identification and verification were done manually, which impacted customer satisfaction and operations. The shift from manual identification and verification to automated processes has streamlined operations and enhanced customer satisfaction. Now, agents can instantly access a customer's history, allowing for a more personalised and efficient service experience. This technological advancement underscores the importance of innovation in customer service

High Maintenance Costs

Maintaining and upgrading existing on-premises PBX and contact centre systems can be costly and time-consuming. Organisations incur hardware procurement, software licensing, maintenance, and IT support expenses. Teams Enterprise Voice and Anywhere365 Contact Center eliminates the need for upfront capital investments and ongoing maintenance costs associated with on-premise systems, offering a subscription-based pricing model that includes all upgrades, updates, and support services.

Limited Flexibility and Mobility

The existing PBX systems lack the flexibility and mobility required for modern banking operations. Employees were restricted to using desk phones or accessing limited features remotely. Teams Enterprise Voice and Anywhere365 Contact Center provide flexible and mobile-friendly solutions that enable employees to work from anywhere, using any device, and access advanced communication and collaboration tools, such as mobile apps, softphones, and web-based interfaces.

Single Point of Failure

The PBX and contact centre systems are susceptible to single points of failure, such as hardware malfunctions, power outages, or network disruptions. These failures can result in downtime, service interruptions, and loss of productivity. Teams Enterprise Voice and Anywhere365 Contact Center offer redundant, geographically distributed infrastructure with built-in failover mechanisms, ensuring high availability and uninterrupted service for banks and their customers.

Align with best practices and Industry standards and meet regulatory laws

To align with best practices and industry standards while meeting regulatory laws, The old, outdated contact centre systems could not meet these laws. In Ghana, financial institutions must adhere to the regulatory framework set by the Bank of Ghana around recording, efficient customer service, etc. Upgrading to a modern system that is flexible and scalable will ensure compliance with these regulations and position the contact centre to meet future demands. Also, the current trends indicate a shift towards omnichannel customer support, cloud computing, and the implementation of AI to enhance customer experience and operational efficiency.

Limited Scalability

The existing traditional PBX and contact centre systems have limited scalability, making it challenging for ABSA Bank to adapt to changing business needs and accommodate growth.

Social Impact

ABSA Bank implemented a VoIP solution, Anywhere365 Contact Centre, to address these issues, integrated with Microsoft Teams. Anywhere365 is a cloud-based platform that offers scalable solutions to handle fluctuating call volumes and customer interactions without requiring additional hardware or infrastructure investments. This solution eliminated the need for upfront capital expenditures and ongoing maintenance costs associated with on-premises systems. The subscription-based pricing model includes all upgrades, updates, and support services.

The Anywhere365 Contact Centre platform is flexible and mobile-friendly, allowing employees to work from any location using any device. Advanced communication and collaboration tools, including mobile apps, softphones, and web-based interfaces, enhance productivity and efficiency. The platform also features redundant, geographically distributed infrastructure with built-in failover mechanisms, ensuring high availability and uninterrupted service for ABSA Bank and its customers.

The project was executed in two phases: the Teams Enterprise Voice, which enables Teams users to make inbound and outbound calls to PSTN lines, and the Anywhere365 unified Contact Center.

Integrating a third-party Unified Contact Centre (UCC) platform with a Teams phone system, as in the case of ABSA bank, involves several critical steps to ensure seamless operation and security. Using an E1 to SIP converter is essential for maintaining existing PSTN lines while enabling compatibility with the Session Border Controller (SBC) for direct routing within Teams. Security is paramount, especially for financial institutions like ABSA bank, which necessitates the establishment of an IPsec VPN to safeguard voice traffic between the on-premises environment and the SBC hosted in the Azure cloud. Deploying robust firewalls, such as FortiGate on-premises and Sophos in Azure, provides an additional layer of protection. The Audiocodes SBC, positioned behind the Sophos firewall, plays a crucial role in managing voice traffic, leveraging defined routing rules to facilitate communication between the Internet Telephony Service Provider (ITSP), Teams, and the Anywhere365 Dialogue Cloud. This intricate setup exemplifies the careful planning and execution required to integrate advanced telecommunication systems with existing infrastructure while prioritising security and functionality without impeding productivity.
