Lost audio stream

Hi everyone, here's a situation I could use some help with. Please be aware that I'm not an IT person at all and had never heard of Wireshark until a couple of days ago; I'm just trying to perform a specific task.

I did a 2h+ phone interview and tried to capture it using the packet capture feature of my AVM Fritz box. Everything went fine until after about half an hour, the phone connection was interrupted and I had to call my interviewee again. I probably should have stopped and restarted the capture at that point, but I didn't think of doing that.

After I finished the interview I tried to extract the audio streams from the resulting .eth file, which had run to about 240mb. I find the first half hour of my interview and also another call my wife made during that time, but not the whole rest of the interview.

The second call to my interviewee shows up in Telephony - VoIP Calls, but I can't play it... the box comes up empty. I also can't find it under Telephony - RTP - RTP Streams.

So my hope is that the stream is still there somewhere in the .eth file, but Wireshark just can't find it. Is there any chance I might retrieve it and not have to do the interview all over again?

Thanks for any help you can give. - Christian
