Summary:                    [patch] reworked chan_ooh323
Description: 
There is patch to asterisk-addons-1.6.1.0 for reworked version of 
chan_ooh323 channel module.

main subject of changes is performance and scalability improvement.
one processing thread is replaced with many threads (one for cmdChannel
of EndPoint, one for incoming call creation, one for call processing).

chan_ooh323 with this reworking is more stable and have good performance
in compare with chan_h323.
chan_h323 have memory leaks in all my asterisk systems (which have
versions from 1.2 up to 1.6.1) and grow more than 2Gb virtual memory after
proccessing about 200000 calls. After many years of solving this trouble i
cancel this work and begin work on chan_ooh323.

asterisk 1.6.1 with this version of chan_ooh323 have uptime 4 days and
proccess about 400 000 calls and have 98Mb virtual memory with 4 active
channels and no memory leak detected by asterisk malloc debug system.
(all modules include OOH323 stack code are compiled with MALLOC_DEBUG
options)
Before testing 1.6.1 i work with 1.4 version and had 8 days uptime
asterisk with more than 1000000 calls processed without leaks.

Also there is small changes for new options - incoming call limit, 
numbering of calls, t35country code and vendor/version identification
(albania code is not liked for me ;))

More detail list of changes/improvements is in Changes-ooh323.eng.

Hello,

Code is on reviewboard now, request 324. Cleanup portion of code is not
big and new functionality portion also. Main code difference is reworked
existing code with changed data stucture and changed processing logic. 
I think it will more comfortabe to see this code as complete code, not a
patch to source chan_ooh323 and ooh323 stack.

I think that main work for cleanup is done and functionality addition must
be paused until code will reviewed.

About t.38. It work with 2 modes, in first mode t38 is hidden from bridged
channel or application and second mode must be compatible with chan_sip
implementation of t.38, it is compatible and work with t38 faxing
applications at least.
