The Federal Communications Commission (FCC) of the United States has added to HAC FAQ to provide guidance for PAG testing a 5G Sub 6 interim procedure to include OTT voice services.
The document 285076 D03 HAC FAQ v01r02 has been replaced by 285076 D03 HAC FAQ v01r03. This new document added to Question 9.
The current problem for laboratories is the inability to establish 5G sub 6 VoLTE or OTT voice calls over 5G NR F1 air interfaces using current call boxes. The update has created an interim PAG procedure to address the issue.
