Stm>After spending couple of days, reading the source and and make file sources,
Stm>i am now able to install mod_h323 in fedora/centos (32 bit or even 64 bit
Stm>system). But when it has to face real world calls scenario, it does not
Stm>really makes any sense the level of audio quality i am listening now.

Stm>- Non stop 3/4 hours i just played mod_h323 and British telecom premium call
Stm>termination route. (honestly mod_h323 really have some problem, somewhere)

Stm>Highest priority, for mod_h323 Audio problem:
Stm>===================================

enable late negotiation and put fs in transconding mode.

Stm>1. mod_h323 cant handle IVR audio/sound to other legs
Stm>
Stm>2. When call is bridged with SIP user and H323 user ( both parties cant
Stm>communicate because there is drop of audio, latency is very low, very bad
Stm>audio quality)
Stm>
Stm>3. H323 to H323 calls, have same audio issue, i just tried to tune to some
Stm>point, but i just cant make it work!

Stm>Less priority, Freeswitch instance problem, while using mod_h323:
Stm>===================================================
Stm>
Stm>1. When mod_h323 is loaded, and i want to shutdown freeSwitch instance, i
Stm>cant, FS gets freezed.
Stm>
Stm>2. I need to reboot server either physically or init 6 for every restart of
Stm>FS instance.
Stm>
Stm>3. Risk of segmentation fault
