I just took a quick look at the dump with Wireshark, its possible to
safe the raw RTP payload from within Wireshark and it looks OK (31-byte
EFR packages starting with 0xC in the high nibble). However I have
no ready-made EFR decoder available so I can't decode the speech.
I did play a little bit with the EFR reference implementation from
GSM 06.35. Its possible to convert the data and I can understand a few
words (a "Yes" at the beginning and a "Bye" at the end). However it
seems
that several RTP packages are missing, also the RTP Analysis Tool of
Wireshark says so (according to it more than 80% is missing). Anyway,
basically EFR decoding seems to work as expected.
Best regards,
Dieter
