When segmented by service, the voice termination subsegment is expected to command 61.70% of the total market revenue in 2025, affirming its leadership in the market. This position has been sustained by its fundamental role in enabling carriers to complete international calls efficiently while maintaining profitability.
Rising global call volumes, coupled with the increasing need for reliable and high-quality call completion, have reinforced the importance of voice termination services. Carriers have focused on optimizing termination routes and leveraging partnerships to lower costs and enhance service reliability, which has contributed to the segment’s sustained growth.
Growing customer expectations for clarity and consistency in international calls have motivated providers to prioritize robust termination infrastructure, further entrenching this segment’s leading share.
Segmenting by transmission network reveals that the owned network subsegment is projected to capture 54.3% of the market revenue in 2025, establishing itself as the dominant approach. This has been driven by carriers’ preference for maintaining control over their infrastructure to ensure service quality, reduce latency, and manage costs effectively.
Owned networks have allowed providers to optimize capacity utilization, secure critical routes, and differentiate their offerings in a competitive market. The ability to guarantee higher security, comply with regional regulations, and deliver consistent service levels has made owned networks the preferred choice among leading carriers.
Long-term investments in upgrading owned infrastructure have also provided operational advantages and cost efficiencies, underpinning this segment’s leading market position.
When viewed by technology, the VoIP subsegment is forecast to hold 68.5% of the total market revenue in 2025, positioning it as the dominant technological solution. This dominance has been enabled by the substantial cost savings, scalability, and flexibility offered by VoIP compared to traditional circuit-switched technologies.
Carriers have increasingly migrated to VoIP to capitalize on improved bandwidth utilization, integration with data services, and compatibility with modern communication platforms. The ability to support advanced features, accommodate higher traffic volumes, and align with the shift toward all-IP networks has further accelerated VoIP adoption.
Competitive pricing and the growing availability of robust VoIP infrastructure have reinforced its leadership, making it the preferred technology in the international wholesale voice carrier landscape.
The international wholesale voice carrier market is witnessing robust expansion, driven by intensifying global communication demand, liberalized interconnection frameworks, and soaring VoIP traffic. Opportunities are emerging in AI-based routing, cross-border service bundles, and underserved regional expansion. Trends such as consolidation via mergers, advanced fraud prevention tools, and IoT-focused voice services are shaping the ecosystem. Restraints include regulatory complexity, legacy infrastructure dependency, and price competition from OTT providers. Providers investing in integrated IP platforms, least-cost routing analytics, and multi-service bundles are viewed as best positioned to lead through 2025–2026.
The market growth has been driven by growing cross-border connectivity requirements linked to business expansion and remote work adoption. In 2024, wholesale carriers reported higher VoIP traffic volumes, with enterprises demanding scalable, low-latency connections across global hubs. The migration from legacy circuit-switched systems to IP-based networks has accelerated, allowing carriers to expand international voice origination and termination services. Enhanced routing quality and lower operational costs achieved through IP platforms are seen as critical to strengthening wholesale agreements. It is believed that demand from CPaaS providers and enterprise communication solutions will further amplify this trend.
Opportunities are expected to emerge with the growing shift toward hybrid generator solutions combining diesel and battery storage systems for construction sites. In 2025, several leading rental companies introduced offerings featuring fuel optimization and remote load management. Hybrid systems are being adopted to reduce operational costs and dependency on volatile fuel pricing, especially in regions with unstable grid supply. Opportunities are also increasing in rental equipment supporting renewable energy integration for off-grid construction projects, which are gaining prominence in emerging economies where infrastructure expansion requires flexible and energy-efficient temporary power solutions for sustained project timelines.
The market is witnessing mergers and partnerships aimed at expanding geographic reach and network redundancy. During 2024 and 2025, consolidation initiatives among mid-tier carriers improved scale and cost efficiency. Another notable trend is the introduction of bundled services combining voice with messaging, CPaaS offerings, and virtual number allocations for enterprises. Blockchain-based inter-carrier billing pilots and advanced fraud mitigation platforms have also been implemented to enhance trust and transparency in wholesale operations. It is anticipated that carriers embedding multi-service and compliance-driven solutions will create a competitive edge in a price-sensitive environment.
The market faces regulatory and competitive challenges impacting profitability. Inconsistent interconnect tariffs across regions and licensing restrictions in certain jurisdictions create operational hurdles for wholesale carriers. Over-the-top applications providing low-cost or free international calls continue to erode traditional wholesale revenues, particularly among retail consumers. The pressure to reduce termination rates due to regulatory reforms in Europe and Asia has further compressed margins. Carriers lacking diversified digital service portfolios or strong partnerships may struggle to sustain profitability in the face of rapid OTT penetration and pricing competition.
