User manual

H.323 Start 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).
FAX Mode Option
T.30/T.38 real-time FAX compliant Voice/FAX auto-switch.
The T.38 is a “Real Time Group 3 Fax Communication over IP network” format. That’s meaning it’s
a protocol for Fax over IP. You have to enable this function
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.
Pass NAT:
If this function is enabled and gateway was implanted under NAT device, the H.323 VoIP call also
can routed to internet without changing the NAT device configuration. (Note: Need collaborate with
DGK).
Pass NAT ID :
If PassNAT was enabled , you need to assign an ID number (1 ~ 10 ) to the Gateway under the
same NAT/firewall device. For example, there are three Gateways under NAT/firewall devices, you
should assign an ID for each of the three Gateways and the three ID numbers are different each
other.(Note: Need collaborate with DGK).
H.323 call auto answer mode:
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.
