You can tcpdump and then use wireshark to graph the calls. When the dump is displayed in wireshark, select 'Statistics' -> VoIP Calls. You will see a display of all VoIP calls. Select the one you want graphed, or select them all and you will see REINVITE and REFER interaction as well as RTP streams.
Thank you very much, jonathan, for your interest! I use ngrep+wireshark many times a day, but I'm affraid it is not suitable for that amount of data. Even with few hundreds MiBs of pcap file wireshark becoms very slow and I can't imagine how to load 50-100 GiB file with milions of calls and try to search for one of them :-) And, even worse, I should "rotate" the file and, don't end with call divided to multiple files...
