The demand for remote accessibility, combined with IT centralization, continues to boost adoption across all sectors.

RESTRAINT

Complexity of integrating legacy infrastructure

Despite widespread acceptance, many enterprises—especially in regions like Latin America and Eastern Europe—still operate legacy analog PBX systems. The complexity of integrating IP telephony with legacy equipment leads to high switching costs and system compatibility issues. For instance, over 38% of small businesses in South America reported interoperability concerns in a 2023 industry survey. Migration also often requires workforce retraining and infrastructure overhaul, such as VoIP gateways or SIP trunk provisioning. Additionally, the initial implementation may require downtime and expensive network upgrades, slowing adoption in regions with aging telecom infrastructure.

OPPORTUNITY

Expansion of cloud-hosted IP telephony in SMEs

The small and medium-sized enterprise (SME) segment is witnessing rapid adoption of cloud-hosted IP telephony. Cloud IP PBX solutions, which reduce upfront hardware costs, have seen a 54% increase in deployment among SMEs with fewer than 100 employees. These systems offer scalability for growing organizations and integrate easily with SaaS tools. In 2023, over 41% of SMEs in Asia-Pacific utilized cloud VoIP services compared to 29% in 2020. Cost-efficient subscription models and vendor-managed maintenance services are encouraging uptake in emerging markets such as Vietnam, the Philippines, and South Africa. As broadband penetration continues to expand, cloud-based IP telephony presents a significant opportunity for telecom providers targeting under-digitized regions.

CHALLENGE

Rising cybersecurity concerns in IP-based systems

Cyber threats remain a major challenge in the IP telephony landscape. Voice over IP systems are susceptible to attacks like eavesdropping, spoofing, and denial-of-service (DoS). Over 25% of enterprises reported VoIP-related cyber incidents in 2023, and telecom fraud losses globally exceeded $32 billion. The need for secure session border controllers (SBCs), encryption protocols like SRTP, and regular firmware updates is imperative, yet only 62% of vendors offer full-spectrum security solutions. Regulatory compliance such as GDPR and HIPAA for call recording further complicates implementation, especially for healthcare and finance sectors. Inconsistent adherence to security best practices across regions poses a risk to data integrity and service continuity.
