Improving ROI and operational efficiency with Global SIP Connect

Business impact: Cost optimisation, simplified management, and seamless global collaboration

The organisation’s transition to Global SIP Connect delivered immediate and measurable business value. International call spend was significantly reduced across regions, supported by multiple built-in optimisation levers that ensured cost efficiency without compromising quality.

In addition, the solution enabled easy, network-wide voice connectivity for globally distributed teams. By unifying voice communications on a single platform, the organisation eliminated fragmentation, improved collaboration, and established a consistent user experience, regardless of location.

This transformation allowed the business to focus on growth and customer engagement rather than the complexities of managing disparate telecom providers.

The challenge: Supporting a follow-the-Sun operating model with legacy voice systems

The organisation operated a globally distributed business with teams and customers spread across multiple time zones. To support round-the-clock operations, it followed a ‘Follow the Sun’ model, requiring seamless voice connectivity across regions.

However, the existing voice infrastructure relied heavily on multiple in-country telecom providers, resulting in high international calling costs, inconsistent call quality, and complex vendor management. Fragmented networks made it difficult to maintain service levels, while limited visibility restricted the organisation’s ability to optimise performance and costs.

The company needed a modern voice solution that could:

• Reduce escalating international call charges

• Deliver consistent call quality across geographies

• Simplify network and vendor management

• Support 24/7 global operations with high reliability

The solution: A unified, enterprise-grade global voice platform

Tata Communications implemented Global SIP Connect, delivering an enterprise-grade voice solution built on MPLS-based SIP trunking.

This solution replaced disparate in-country providers with a single, standardised global platform. Intelligent call routing ensured calls followed the most efficient paths, while Quality of Service (QoS) optimisation prioritised voice traffic to maintain high call quality across the network.

Key elements of the solution included:

• Centralised SIP trunking across global locations

• Intelligent routing to optimise call paths and costs

• MPLS-based connectivity for predictable performance and reliability

• Unified management and visibility across all voice traffic

The result was a simplified, scalable voice infrastructure aligned with the organisation’s global operating model.

Why Global SIP Connect outperforms traditional providers?

For a modern enterprise, communication must be borderless. While traditional in-country providers offer local depth, they create a fragmented "patchwork" of contracts, disparate SLAs, and administrative complexity. Conversely, generic SIP trunking often relies on "grey routes" that compromise quality and regulatory compliance.

Global SIP Connect by Tata Communications eliminates these trade-offs. By consolidating your voice estate into a single, cloud-native network spanning 100+ countries, you replace regional silos with a unified global standard.

Key advantages include:

• Compliance: Fully licensed services that navigate complex local regulations and emergency calling (999/112) requirements.

• Integration: Seamless, carrier-grade peering with UCaaS leaders like Microsoft Teams and Zoom, reducing latency.

• Efficiency: One contract and one centralised portal, leveraging our Tier-1 infrastructure to slash "middleman" costs.

Don’t just connect; unify. Global SIP Connect provides the reliability of a local carrier with the unmatched scale of a global leader.

The results: Tangible gains in cost efficiency and service quality

With Global SIP Connect Solutions in place, the organisation achieved measurable improvements in both cost efficiency and operational performance.

• Significant reduction in international call expenditure

• Improved call quality and reliability across all regions

• Seamless support for 24/7 global operations

• Simplified communications infrastructure through standardisation

Employees benefited from a single platform for all inbound, outbound, and on-net calls, removing complexity and improving collaboration.
