Asterisk talking to Alcatel OmniPCX PBX using H323

SYSTEM
Asterisk@Home 1.1
CentOS release 3.4 (final)
Linux version 2.4.21-27.0.1.EL
Wildcard FXO: Generic Clone (for meetme conference hardware timing!!! if fxo is not present then bad conference.)

Alcatel OmniPCX software version 4 (only H323). SIP protocol only from version 5…

APPLICATION
meetme conference incoming call (SIP phones, ZAP FXO, Alcatel OmniPCX H323)
User call OmniPCX, OmniPCX call asterisk via H323 at number 9999, asterisk receive call in from-internal context…
9999 is menu program for conference select.

Last Problem :
If conference is opened by user from Alcatel OmniPCX then only this user receive bad audio…if user recall no problem. Conference is good. Conference is not very stable. Please wait network testing…
