Tool for splitting voip calls to separate files

1

Hi,

I have to deal with very large pcap files which include many voip (h323, sip, isup) calls. Of course it takes a lot time to open these large files and find the correct call on a desktop computer. Is there a tool to create individual pcap files for each voip call from a large file ?

Thanks.

You can use Wireshark Lua to do this. Try this Lua script.

Thanks. It seems that this example only covers SIP calls. Where can I find more examples ? maybe an H225 , Q931 , ISUP equivalent ?

Lua is something I didn't know. It seems we can make use of it, but I need to learn a lot.
