What is VoIP?

VoIP stands for Voice over Internet Protocol. It is also referred to as IP Telephony or Internet Telephony. VoIP refers to communicating via the Internet, rather than the Public Switched Telephone Network (PSTN). The basic steps involved in originating an Internet telephone call are conversion of the analog voice signal to digital format and compression/translation of the signal into Internet protocol (IP) packets for transmission over the Internet. This process is reversed at the receiving end.

Voice over Internet Protocol (VoIP) is a voice line that runs through an Internet source. VoIP uses the Internet connection to make or receive telephone calls. (e.g.: Skype, MSN voice chat, Yahoo messenger voice chat…etc)

The difference is that Exetel assigns customers with individual VoIP DID (Direct in Dial) numbers for local Australian areas and our servers are located in Sydney rather than internationally.

VoIP does not have any contract periods .

What is a VoIP DID?

A VoIP DID allows customers to have the ability to receive calls on their desired location (e.g.: A person that lives in NSW could have Queensland number (DID) which allows the receiver's friends to have cheaper call rates.)

This is also applicable for overseas use, provided there is an Internet source a VoIP service can registered to use. (e.g.: An Australian VoIP DID is registered in Thailand and could call back to Australian numbers and be charged the same rates as a local call VoIP calls) If calls are received then the receiver's friends or relatives would be charged the same as a local phone call.

DID (Direct In Dial) number is very similar to the Telstra number so that other people can call you on .

If I have a VoIP service, who can I call?

With a VoIP service you can call anywhere exactly like a switched phone service.

What is the quality of VoIP calls?

Quality of a VoIP call is similar to a PSTN phone call. However, VoIP call clarity depends on the internet speed.

What are the prerequisites to obtain VoIP Service?

In order to obtain VoIP service, a broadband (high speed Internet) connection is required such as Exetel’s ADSL product. You can hook up an inexpensive microphone to your computer and send your voice through an ADSL MODEM or connect a phone directly to a telephone adapter.

If you have a handset connected to an ATA/Modem, simply dial as you would normally. If you are using soft phone software with a microphone and headset, you can use the keypad on your computer keyboard or your mouse to dial the number.

What ADSL speed do you recommend for VoIP?

Minimum speed recommended for VoIP is 512/128 or faster, the faster the speed the higher you can raise the codec which means less compression.

Speeds slower than a 512/128kbps is not recommended for a VoIP connection because there may be quality issues.

Which MODEM is recommended for VOIP?

Technical assistance is provided on Netcomm and Dynalink modems. If you currently do not have a VoIP modem and looking to purchase one, please see other methods of using VoIP

No, You need not have a static IP address for VoIP since VoIP supports devices operating in DHCP mode as well.

Do I need to put a Micro filter on the back of phone where the VoIP gets connected?
