Hi:

I've used this one http://www.voipmonitor.org/ I don't think it can record T.38 but it's a great tool. You can save a pcap file for every call, you can have the MOS score of each call and you can save RTP as well as a wav file.
You can also try this one http://oreka.sourceforge.net/

I think that with Kamailio, RTP proxy and/or sems you should be able to configure something that records your calls.

Best regards,
Sebastian Ferguson

Hi all!

Do you know any comfortable tools to filter out a certain users call? e.g. searching in SIP packets for the user pattern, get the media port out of SDP and capture also RTP+T.38

I found pcapsipdump but have not tried it yet.

Any suggestions or do I have to write my own tool?

thanks
Klaus
