(Reuters) -U.S. communications solutions provider iBASIS has signed a deal with Australia's Telstra Group to acquire wholesale voice, mobile, and messaging customer contracts from Telstra International, it said on Wednesday.

The acquisition, expected to close before year-end 2025, marks the establishment of iBASIS' presence in Australia and New Zealand, expanding its footprint in the Asia-Pacific region, the U.S.-headquartered company said.

iBASIS will also obtain exclusive rights for international wholesale voice services for Digicel Pacific, part of the Telstra International portfolio, covering several Oceania countries including Papua New Guinea, Fiji and Samoa.

Telstra International is the global arm of telecom operator Telstra, and is a digital infrastructure and connectivity partner in Asia Pacific.

Telstra did not disclose a transaction value after a Reuters' request via e-mail.
