Which L3 message (UMTS) telling about the used AMR codec?
Hi Guys
Do you know which L3 message I should check in order to know if the call using AMR 12.2kbps or 5.9 kbps?
btw, the log is not a drive test log file, can not open with any drive test post processing tool. So, I can only check from the message but can not find the right one yet.
Thanks

Thanks guys. It's the exported file from the RNC log. I saw the class a, b, c bit size matched to 12.2 kbps AMR. So, it supposed to be 12.2 kbps one.
Do you guys have any half rate AMR log file? (TEMS or Nemo are ok) If you have, could you share, please? I just want to see how the actual half rate signaling look like.
