Dear FS H323 author and experts, With all my respect, I never saw till today H323 audio quality can be that much bad compared to my past years audio experience with quintum/cisco gateways. Info: === After spending couple of days, reading the source and and make file sources, i am now able to install mod_h323 in fedora/centos (32 bit or even 64 bit system). But when it has to face real world calls scenario, it does not really makes any sense the level of audio quality i am listening now. - Non stop 3/4 hours i just played mod_h323 and British telecom premium call termination route. (honestly mod_h323 really have some problem, somewhere) - I just planning to switch back to SIP :o( Highest priority, for mod_h323 Audio problem: =================================== 1. mod_h323 cant handle IVR audio/sound to other legs 2. When call is bridged with SIP user and H323 user ( both parties cant communicate because there is drop of audio, latency is very low, very bad audio quality) 3. H323 to H323 calls, have same audio issue, i just tried to tune to some point, but i just cant make it work! Less priority, Freeswitch instance problem, while using mod_h323: =================================================== 1. When mod_h323 is loaded, and i want to shutdown freeSwitch instance, i cant, FS gets freezed. 2. I need to reboot server either physically or init 6 for every restart of FS instance. 3. Risk of segmentation fault Many thanks & Best regards
