Description The H.323 Options parameters allows you to specify H.323
Version 2 features that allows for:
• DISABLE_FAST_START - The Vanguard H.323 Version 2
implementation supports FAST START or FAST CONNECT
and automatically opens audio channels. If the H.323 Options
parameter is configured for DISABLE_FAST_START, FAST
START is not used.
• DISABLE_H245_TUNNELING - The Vanguard H.323
Version 2 implementation automatically enables tunnelling of
H.245 messages over a H.225 TCP session. If H.323 Options
parameter is configured for DISABLE_H245_TUNNELING,
H.245 messages are not tunnelled over the H.225 TCP
session. Instead a separate TCP session is used for H.245
messages.
• BLOCK_SETUP_ACK - This prevents the Q.931 SETUP
ACK message from being transmitted.
• BLOCK_PROGRESS - This prevents the Q.931 PROGRESS
Message from being transmitted.
• PREPEND_CALLING_TO_CALLED - This function copies
the calling number to beginning of the called number.
• BLOCK_ALERTING - This function prevents the Q.931
ALERTING Message from being transmitted.
