[asterisk-users] OT, free software for SIP ladder diagrams?

[Steve Edwards]

I was debugging a turnup with Global Crossing the other day and they 
presented me with a web page that displayed a 'ladder diagram' of a call 
including a ton of detail all neatly organized in tabs and links so you 
could drill down to any level of detail needed.

Is there any free software available to analyze a pcap or similar packet 
dump with similar features?
