The ACCC has today commenced a public inquiry to decide whether to extend, vary or revoke the declaration of the domestic mobile terminating access service (MTAS) i.e. the wholesale markets for call and SMS termination. The ACCC notes that the Australian mobile industry has changed significantly since 2014, when the current declaration was made. As OTTs, Voice over LTE (VoLTE) and Voice Over WiFi are more and more commonly used, the ACCC is now considering whether the declaration of the MTAS is still necessary. Submissions to the consultation are invited by 14 September 2018.
