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 -- Dieter Spaar, Germany spaar at mirider.augusta.de
