[Serusers] Reg. SIP Scenario Generator

[Balaji Bapulal Thoguluva]

Hi,

   I would like to know if anybody has used SIP Scenario Generator software. I saw this from this website http://www.iptel.org/~sipsc/ 

    If any body has already used it, I would like to know what kind of file is given as input to it. The document says any libpcap formatted file can be given as input. I guessed tcpdump files produces lipbcap formatted files. But it doesnt seem to work. I would appreciate if anybody could tell about what is lipcap  formatted file and how I can generate it. 

Thanks,
Balaji
