H.323 Mode
This selection could force the Gateway to use normal start mode
(default mode) or fast start mode when establishing a VoIP call. Many
other gateways only support normal start mode, enable this selection
when it is necessary. The default is disabled (using fast start mode).
H.323 H.245 Tunneling
This selection could force the Gateway to use H.245 Tunneling when
establishing a VoIP call The default is disabled (using fast start
mode).
H.323 Registration type
There are 2 choices for this setting. “Gateway” means it will act as the
VoIP gateway. “Terminal” means it will act as the IP phone terminal.
H.323 RRQ TTL
This command configures the number of seconds that the gateway
should be considered active by the H.323 Gatekeeper. The gateway
transmits this value in the RRQ message to the gatekeeper.The
default value is “0”.
H.323 Autoanswer
When a VoIP call is incoming, the Gateway will ring a specific phone
set. The H.323 call signaling part could be connected or alerting
during this ringing period. If this selection is enabled, the H.323
signaling part is connected during the ringing period. The benefit of
this situation is that the remote side could hear the status of the
specific port. That is, the remote side will hear ring back tone if the
Gateway is really ringing the phone set. If the phone set is busy, the
remote side will hear busy tone. The disadvantage of this situation is
that the H.323 connected time is not the real voice call connected
time. So, if billing is recorded for this Gateway, this function should be
disabled.
MAC Authentication
Some Gatekeeper register need UA send MAC address to
Authentication, you need enable this function.(Default is disable).
Watchdog
When your gateway shutdown, or something happen that made
gateway can’t work fine. Watchdog will reboot your gateway
automatically when it can’t work.
