iBASIS to Acquire Telstra International’s Wholesale Voice, Mobile & Messaging Contracts
iBASIS, a leading provider of communications solutions for operators and digital players worldwide, announced it has signed an Asset Sale and Purchase Agreement (APA) with Telstra to acquire Telstra International’s wholesale voice, mobile, and messaging customer contracts.
The transaction, which is subject to regulatory approvals, represents a major expansion of iBASIS’ commercial scale, geographic reach, and customer portfolio across the Asia-Pacific region, reinforcing its presence in Hong Kong and Singapore, and establishing its presence in Australia and New Zealand.
Additionally, iBASIS will obtain exclusive rights for international wholesale voice services for Digicel Pacific, part of the Telstra International portfolio, covering Papua New Guinea, Fiji, Samoa, Tonga, Vanuatu, and Nauru.
The transaction further underpins iBASIS’ positioning as the partner of choice to Tier One domestic carriers for international wholesale services and consolidator of the international wholesale market.
The transaction involves the transfer of high-value customer contracts and an international team of seasoned commercial and operational professionals. iBASIS is committed to ensuring a seamless transition with uninterrupted service quality for all customers. Existing customer relationships will remain intact and fully supported throughout the integration process.
The transaction is subject to regulatory approval and is anticipated to close before year-end 2025. Dohan Advisory served as the financial advisor to iBASIS in relation to the transaction.
Roary Stasko, CEO of Telstra International
This long-term partnership with iBASIS offers a strategic opportunity to strengthen our ability to compete globally, while ensuring continuity and quality for our international voice customers. We have full confidence in iBASIS to deliver seamless continuity for our wholesale and retail customers, backed by their proven track record in service delivery and global expertise
Patrick George, CEO of iBASIS
We are extremely proud to partner with Telstra. This marks a significant milestone in iBASIS’ ongoing consolidation strategy. This transaction accelerates our growth trajectory and strengthens our unique leadership position as a global wholesale player. It validates the relevance of our model as an independent specialist in global wholesale communications, built on high-performing voice and mobile platforms, and expands our reach and presence in the APAC region
Final thoughts
The Telstra deal positions iBASIS as a stronger consolidator in APAC, securing scale and unique Pacific routes that few competitors can match. Unlike BICS, which leverages its operator ownership to dominate roaming and digital identity, iBASIS continues to expand as an independent integrator—consistent with Tofane’s track record of absorbing carrier units like SFR, NOS, and Simfony.
The timing aligns with industry dynamics: wholesale voice is under structural margin pressure, but concentration of routes improves quality, fraud resilience, and enterprise appeal—mirroring moves by Orange International Carriers and Deutsche Telekom Global Carrier. At the same time, rising A2P and RCS volumes in APAC create incremental upside, even as CPaaS specialists such as Sinch and Infobip compete more aggressively on enterprise messaging.
If execution mirrors past integrations, iBASIS could consolidate its role as the leading independent wholesale provider in APAC, balancing scale, reliability, and strategic neutrality in a market still shaped by operator-backed incumbents.
