I guess for some reason Wireshark is just missing the data.

I tried it in the meantime. No problem at all. The git version works as expected and Wireshark does not miss any packets here, each call is about 30 seconds. I tried it with EFR and FR, Wireshark can save the RTP payload, for EFR I had to convert the data first so that they fit to the GSM 06.35 reference implementation (they use a strange format which stores every bit into two bytes). For FR, Toast can convert the payload immediately. Tested on Windows XP and cygwin, Wireshark and bsc_hack running on the same machine.
