Verint SIP Bye Handler

Successfully solves the problem between Cisco UCM and recording server when CUCM recording calls stuck in preserved mode until SIP Trunk reboot. Details of the bug are here: https://tools.cisco.com/bugsearch/bug/CSCuv29131 The application itself works by parsing log files for call-id strings and closing found calls by sending SIP Bye requests. More information how exactly this application works is in detailed comments in source code files.

Requirements

Java Runtime Environment 1.8.
Network access to Verint cluster or any other recorder with similar SIP BYE problem.
Can work on any OS with JVM (Windows, Linux, Mac OS, toaster, etc).

Install latest JRE from http://java.com. If you install this application on a server which already has any applications using Java, then you should instal JRE to custom directory, not in default, to avoid any possible issues with backward compatibility.
Download latest release of Verint SIP Bye Handler and extract zip archive in needed place.
Configure settings in etc/config.properties. You should at least specify SIP number of the recorder, risLogFolderLocation and callTerminationTimeout. See detailed comments about each property in the etc/config.properties.
Setup new rule in Task Scheduler (Windows) or Cron (*nix) with trigger every 5 minutes (or more) and executing (%path_to_JRE_folder%/bin/javaw -Dlog4j.configurationFile=etc/log4j2.xml -jar verintbyehandler.jar and working directory (Start in) as path to folder with extracted Verint SIP Bye Handler.
- In case of installing on Linux - just write simple script: cd and mentioned above java command, and execute it in Cron.
Run created task and check /etc/application.log for any errors or exceptions.

Added new configuration timers: sipByeSenderPause and applicationClosingTimer. Detailed description about each timer see in config.properties file.
Fixed bug caused some performance slowdown on processing inbound responses
