Sip Viewer help you view and analyze SIP logs. It aims to output the extracted call flows as simple ASCII ladders directly in the command prompt (or using an eclipse plugin).
Sip Viewer Features:
Parsing:
1. Parse sip logs and aggregate sessions
* Able to match many dialogs in the context of a back to back user agent
* Configurable parser to suit specific log formats.

2. Basic filtering based on indices calculated by the parser is possible. ex. you can query to only expose a specific session or call id.
3. more than 1 file can be provided on command line (useful when logger does rolling)
4. also able to parse gzip files (by example, our environment archives the files each night).
5. note: if you parse big files you might need to extend memory using -Xmx java parameter.

Call Flow:
1. Organize the sip messages into an ASCII ladder.
2. All related traces are linked under the ASCII ladder
3. Name resolution (Reverse DNS) of the actors ip to title the ASCII ladder (configurable, false by default)
4. each arrow is prefixed with a flag to distinguish the call leg (according to call-id).

Requirements:
* Java
