H.323 VoIP Advanced Configuration
There are many H.323, VoIP, Codec and other more detail Setting, you can set in "Advance Setting". For SIP and H.323, there are a little different in
advance setting. There are 3 different parts to setting about VoIP, Telephone and network.
[Advance Setting]
Item Description
After the VoIP call is connected, when you dial a digit, this digit is sent to the other side by DTMF tone. There are two methods of
DTMF Relay for
sending the DTMF tone. The first is "in band", that is, sending the DTMF tone in the voice packet. The other is "out band", that is,
H.323:
sending the DTMF tone as a signal. Sending DTMF tone as a signal could tolerate more packet loss caused by the network. If this
selection is enabled, the DTMF tone will be sent as a signal.
This selection could force the Gateway to use normal start mode (default mode) or fast start mode when establishing a VoIP call.
H.323 Mode:
Many other gateways only support normal start mode, enable this selection when it is necessary. The default is disabled (using
fast start mode).
This selection could force the Gateway to use H.245 Tunneling when establishing a VoIP call The default is disabled (using fast
H.323 H.245
start mode).
Tunneling:
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
H.323
terminal.
Registration
type:
This command configures the number of seconds that the gateway should be considered active by the H.323 gatekeeper. The
H.323 RRQ TTL:
gateway transmits this value in the RRQ message to the gatekeeper. The default value is "0".
When a VoIP call is incoming, the Gateway will ring a specific phone set. The H.323 call signaling part could be connected or
H.323
alerting during this ringing period. If this selection is enabled, the H.323 signaling part is connected during the ringing period. The
Autoanswer:
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.
Some Gatekeeper register need UA send MAC address to Authentication, you need enable this function.(Default is disable).
