Hello Harald,

Using this mode, I have created a pcap file with OML+RSL bringup, followed by one call between two MS (extn. 1005 calls 1003) where all RTP/RTCP packets are visible. The call uses EFR, since that is hardcoded in many places all over OpenBSC at the moment.

The pcap file is available from http://bs11-abis.gnumonks.org/trac/attachment/wiki/nanoBTS/ipaccess-startup-...

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.

Best regards, Dieter
