Where ICT offers real-time voice and connects to other voice ICT, its documentation must state the main specifications through which voice interoperates, covering at least 100 Hz to 7 000 Hz, using either a mutually agreed specification set meeting the standard's voice requirements or ITU-T G.722. Notes survey codecs by technology (SIP with G.722, AMR-WB or Opus; IMS and GSMA IR.92 and NG.114 with AMR-WB and EVS; WebRTC with Opus; emergency interfaces in ETSI TS 103 479; relay in ES 202 975).
This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 1 it maps to, and the evidence behind each claim, over MCP and REST.
