African Roaming Alliance Lab


VoLTE Roaming Lab

What is VRL?

The VoLTE Roaming Lab, formerly known as the VoLTE Roaming Taskforce, was established in November 2019. Since its creation, this group only had MNOs members with Verizon as the chair. It features MNOs from all over the world who collaborate on initiatives to support the delivery of VoLTE Roaming amid challenges like Emergency Calls, Device Manufacturers and Lawful Intercept.

The principle has been simple, to have an MNO only forum where MNOs can identify VoLTE Roaming issues and challenges and in a shared manner, find fixes and share expertise and experience to enable other operators to launch VoLTE Roaming quickly and seamlessly.

Meetings take place every two months. During the sessions, members are asked to contribute and work together to define the workstreams of the lab and set the objectives and action points to tackle each of the challenges mobile operators are facing.

  • Chaired by CKH IOD

  • Deputy Chair by Orange

  • MNOs only

  • Large and small operators globally
