set h323 out_fast_start
set h323 local_alert
Per ITU-T H.323 standard, an H.323 terminal initiating a call sends a Setup message to the
remote gateway, then wait for an Alerting message from remote gateway. Upon receiving the
Alerting message, the H.323 terminal sends ring back tone to the telephony port which
initiates the call. During the period after sending Setup message and before receiving Alerting
message, the caller will experience a period of silence. Duration of the silence period depends
on the network delay. The ITG provides an option for generating ring back tone before the
Alerting message is received from the remote gateway. This command is for selecting if ring
back tone should be generated toward calling telephony port before Alerting message is
received.
set h323 local_alert {on | off}
Syntax Description
on ITG generates ring back tone before receiving Alerting message
from remote gateway.
off Do not generate ring back tone until Alerting message is received
from remote gateway.
Factory default

gateways .
