frequently Asked Questions
Is there any internal wiring required for Digital Voice Global?
No internal wiring is required if you connect your telephone set to the back of the IAD using an ordinary double-ended RJ-11 cable. However,
you need to install internal wiring if you wish to install the telephone set some distance away from the IAD (e.g. another room). Please
inform our Customer Care Consultants upon your subscription to Digital Voice Global service, should you require internal wiring.
We recommend the use of a cordless telephone set should you wish to avoid installing additional wiring.
What is the effective distance from the telephone line to the IAD?
The maximum distance supported by an IAD will be up to approximately 1,000 feet.
What does the IAD do?
The IAD converts analogue voice signals from a standard telephone to digital data that can be transmitted through a broadband device
across the Internet. It provides an alternate means to make voice calls. It also performs a basic routing function to enable simultaneous
voice and data communication.
Is the IAD's power supply compatible with 110v or 220v?
The IAD's power supply is compatible with both 110v and 220v.
How do I know that the IAD is working?
When you power on the IAD, the LED display lights would start to blink. In the operational ready state, the PHONE LED light would turn
solid green. If you plug in your telephone set into the telephone jack at the rear of the IAD, you should hear a dial tone within 5 minutes.
You can start making or receiving calls once you hear the dial tone.
Do I need to keep the IAD powered on at all times? If there's a power failure, can I still be reached?
The IAD needs to be powered on at all times. It would not work if there is a power failure. However, if you subscribe to voicemail, which
is included in the Value Pack and Value PackPlus bundles, your calls will be transferred to the voicemail mailbox.
Does keeping the IAD powered on at all times consume a lot of electricity?
The IAD is a low-power device, so it consumes very little electricity. It is approximately the same as operating a cordless phone.
Does the IAD have standby power back-up?
No, the IAD does not have standby power back-up. It would not work in the event of a power failure, that means you cannot make any
outgoing calls or receive incoming calls.
If you are concerned about power-related disruptions, we would like to suggest that you install a back-up power option such as an
"Uninterruptible Power Supply" (UPS) unit. The UPS would provide back-up power in the event of a power failure, not just for the IAD,
but also for PC and other equipments in the house.
Does Digital Voice Global support answering machines or similar devices?
Most answering machines should work, but some models, especially older ones, may have compatibility issues, as Digital Voice Global
is operating over a newer technology platform.
We recommend that you check with the equipment vendor for more information. Alternatively, you can call our Customer Care at 1633
to subscribe to our Voicemail service.
Can I use multiple phones with Digital Voice Global service?
Yes, some of our customers use cordless phone systems that come with a base unit and extra handsets. The base station of the cordless
telephone plugs directly into the IAD. Multiple handsets can be placed anywhere in the house. However, the Caller-ID display of certain
cordless phone may not work properly with Digital Voice Global.
Can I use my pulse-dialling phone with Digital Voice Global?
No, Digital Voice Global does not support pulse-dialling phones. Pulse dialling is usually found in older model phones, whereas most modern
phones operate on tone dialling. Please check that the phone you intend to use with Digital Voice Global supports tone dialling.
Does Digital Voice Global support dial-up modem usage?
For data communications, Digital Voice Global is designed for optimised broadband connections via its RJ-45 (Ethernet) port that are
available on the IAD. As such, dial-up narrowband data type of communications via the RJ-11 port is not a supported usage.
Does Digital Voice Global support faxing?
Like any other activities over the Internet, faxing over Digital Voice Global is dependent on the network conditions beyond StarHub's
control such as congestion or disruptions. Users may encounter dropped transmission or degradation fax quality. As such, we are unable
to support faxing over Digital Voice Global.
Can I use Digital Voice Global for my home security system?
As your home security system is an essential service, we strongly recommend that you consult your system vendor first before connecting
your home security system to Digital Voice Global. We would be glad to provide any relevant information to your vendor, if necessary.
Please note that your home security system will not work in the event of a power failure, as the IAD does not have standby power back-up.
In the unlikely event that there is a Digital Voice Global outage, your home security system will not work as well.
Can I operate a virtual private network (VPN) application behind the IAD?
Yes, it should support most VPNs operating IPSEC and PPTP, the most common VPN protocols.
