National Telecom Regulatory Authority of Egypt (NTRA) approved voice calls via 4G Technology (VoLTE). In fact, VoLTE service has not been applied in Egypt’s market before, while this step came in response to the several requests made by operators to obtain NTRA’s approval on launching VoLTE service for their subscribers. It is worth noting that NTRA approved to start launching this service, after the operators had met all the necessary technical and regulatory requirements.
