/**
* Testing for deadlock under massive load on the same call.
* This testcase reproduces deadlock that occurs most frequently with TCP thread pool size set to 1
* from this issue https://jain-sip.dev.java.net/issues/show_bug.cgi?id=301
*
* Other related issue is here http://code.google.com/p/mobicents/issues/detail?id=1810
*
* The test sends couple of thousands 180 Ringing responses in order to stall the UAC thread.
*
* The issue is more easily reproducible without debug logs - 300 vs 1000 messages on average
