3.10.6.18.4. Usage Guidelines
This command set up a part of global voice service for VoIP call. Logical channel (voice
channel), based on H.245 procedure can be open before and after a point of time, which the
other party delivers CONNECT by hook off, when the gateway or a remote gateway sets h323
call start to normal.
The call channel is set to late at default. In this process, the other party receives CONNECT
message after hook off, then opening voice channel procedure starts. In this process, the form
end of speech can be cut off. To avoid such a problem from happening, use h323 call channel
early to open the voice channel before hook off.
