A SmartVoice gateway works with all popular transmission technologies
including Cable/DSL, Frame Relay and FDDI (Fibre). Within a data network
environment, your SmartVoice gateway sits behind a modem/router, and your
firewall needs to be "VoIP aware".
The SmartVoice Gateway operates in two modes:
Router Mode (default): the LAN and WAN are on different subnets and
Network Address Translation (NAT) occurs twice through the SmartVoice
gateway and the router.
bridge Mode: if speed is an issue for remote users, bridge mode can be used
where devices are treated as though connected directly to the router/switch.
One of the key applications for a SmartVoice Gateway is toll bypass – ideal for a
business with offices in multiple cities. For example, a business has their head
office in Sydney and branch offices in Brisbane and Melbourne
Application 1 – Inter-Office Communication:
The offices can ring each other for free over the VPN and eliminate long
distance charges for everyday communication
Application 2 – Long distance calling to external numbers
The Brisbane office wants to call an external phone number in Melbourne – the
call is routed to the Melbourne SmartVoice gateway over the VPN and then
hands-off to the local PSTN, in effect making it a local call from Brisbane.
A SmartVoice Gateway allows your business to move beyond the boundaries
of a single location and gives remote staff such as teleworkers or mobile sales
reps access to your office's Internet Telephony Service.
A user simply calls in via a mobile phone or standard PSTN phone to an FXO
port on the SmartVoice Gateway. After entering the security password, you can
pick up the dial-tone for the Internet Telephony Service to call out to interstate
or international phone numbers.
A business with an existing analogue PBX can use a SmartVoice Gateway to add
Internet Telephony services to the phone system without the need to replace
any equipment. The SmartVoice unit simply integrates with the PBX and acts
as a "gateway" for routing calls from a phone extension through to an Internet
Telephony Service Provider. This provides your business with the ability to make
calls through either a regular telephone service (PSTN) or an Internet Telephony
service. Most importantly, the business retains all of its phone functions
managed by the PBX and is transparent to all users.
