2. TPG VOIP
2.1. TPG VOIP is a service which enables you to make and receive voice
calls over your broadband internet connection (ADSL, ADSL2+, Naked
ADSL2+). It is particularly designed for use with TPG's broadband
2.2. TPG VOIP is not intended to be used as a standard telephone service. If your internet is not functioning properly for any reason, including where there is a power failure, data congestion, throttling, or other internet outage, TPG VOIP will not function or will not function correctly.
2.3. TPG VOIP may be used to make and receive calls to/from
(a) Other TPG VOIP customers;
(b) Standard Australian local and national numbers;
(c) Australian mobile numbers in Australia;
(d) 000 emergency services (only for plans where a service number is allocated);
(e) Free phone and local rate numbers such as 13, 1300 and 1800 numbers (only for plans where a service number is allocated);
(f) Directory assistance or operator assisted numbers (only for plans where a service number is allocated);
(g) Satellite phones;
(h) Most International destinations.
2.5. TPG VOIP is not useable for fax transmission, pay TV system dialups (e.g., Foxtel, Austar, Select TV), back to base alarms and other monitoring systems using phone lines, dial up modem and other analogue data calls (e.g., EFTPOS).
2.6. TPG retains the complete discretion to decide the CODEC which will be used for the TPG VOIP service.
2.7. It is a condition of supply of the Service that you must not preselect to another carrier or use the TPG VOIP service to make override calls on a third party network. TPG may terminate the supply of the service if you preselect to another carrier or use the service to make override calls. You agree that you will not request that TPG procure the ability to preselect or override to other carriage service providers.
2.8. In addition, TPG also sells international VOIP minutes via TPG’s VOIP International Gateway. TPG’s VOIP International Gateway is an IP gateway which enables voice calls to be carried to certain international destinations. TPG’s VOIP International Gateway can only be accessed by registered TPG customers and access to the TPG VOIP International Gateway may be achieved by one of the following methods:
(a) by dialling a nominated TPG VOIP International Gateway telephone
number from a Australian telephone service (whether fixed or mobile)
which has been registered with TPG; or
(b) by means of Internet Protocol (IP) connectivity (this access method is not initially available but it is expected that it will become available in due course).
TPG advises you that charges for International VOIP Minutes exclude any charges that you may incur in accessing the TPG International VOIP Gateway. For example, you will probably incur a fixed or per minute charge from your telephone service provider for dialling the TPG VOIP International Gateway. When accessing via IP, you will utilise data quota that may be supplied to you by your IP provider and, in some circumstances, incur charges for the data used in accessing the TPG VOIP International Gateway. Such charges are your responsibility and you should make your own enquiries before deciding to register for and use the TPG VOIP International Gateway service.
3. TPG Home Phone and Landline Rental
3.1. TPG Home Phone and Landline Rental is a standard telephony service
similar to any conventional telephone service. A standard telephone
must be connected to a standard RJ11 telephone socket which is cabled
and connected to a qualified copper pair.
3.2. Calls to numbers starting with 19, 0500 or Universal International Freephone Numbers (UIFN) are not supported.
3.3. TPG uses the copper unbundled local loop (ULL) to supply the service but, in the future, may use an alternative customer access network such as the national broadband network (NBN) to do so. In order to acquire TPG Home Phone and Landline Rental before NBN, there must be an available qualified copper pair at the customer premises. This means that the customer premises will need to have or have had in the past an existing functioning standard telephone service using a copper pair. The qualification of the copper pair to be used for the TPG Home Phone and Landline Rental service will be determined during the application process. Not all copper pairs are suitable. Limitations may include the existence of complex services being supplied over the copper pair (e.g., ISDN, Duet, Securitel, Line Hunt, ADSL2+ etc), and where there is RIM, sub-exchange, pair gain or other network elements affecting the copper pair.
3.4. TPG Home Phone and Landline Rental is not useable for pay TV system dialups (e.g., Foxtel, Austar, Select TV), back to base alarms and other monitoring systems using phone lines, line hunt facilities, dial up modem or other analogue data calls (e.g., EFTPOS). Fax to national numbers in the Telstra, Optus, AAPT and Primus PSTN network is supported; fax to international numbers is not reliable; and VoIP based fax is not supported. Once the TPG Home Phone and Landline Rental service is installed, you will not be able to use the copper pair for telecommunications services supplied by third parties carrier. For example, you will not be able to use that copper pair to acquire broadband from Telstra, Optus or other carriers, though it will be possible to acquire broadband from TPG. Broadband using the Line Sharing Service is not possible.
3.5. TPG may offer a range of features with TPG Home Phone and Landline Rental but is not obligated to do so. Initially, customers should understand that some of the features that might be available with other telephony services, such as caller ID, call forwarding, call hold etc will not be available. If TPG chooses to make such additional features available, the terms under which those features are offered will be stipulated at the time of offer.
3.6 It is a condition of supply of the service that you must not preselect to another carrier or use the TPG Home Phone and Landline Rental service to make override calls on a third party network. TPG may terminate the supply of the service if you preselect to another carrier or use the service to make override calls. You agree that you will not request that TPG procure the ability to preselect or override to other carriage service providers.
4.1 TPG Preselection is a service by which a customer who uses another
carrier as their home phone access provider uses TPG as their provider
for all long distance, fixed to mobile, and international telephone
calls. All other calls are provided by the customer’s home phone access
4.2 You will remain responsible to pay your primary telecommunications supplier for all local calls, access line charges, other value added services and for calls made using another telecommunications supplier’s override code

(c) acknowledge that you have been advised that you may have an agreement with another telecommunications supplier and that there may be consequences under that existing agreement if you change your preselection choice to TPG or its related company.
5. CUSTOMER SERVICE GUARANTEE
5.1. The Customer Service Guarantee (CSG) is a guarantee that is
proscribed under the Telecommunications Act 1997 and gives consumers
certain rights in connection with standard telephone services. These
(a) The right to be provided with information about the CSG and the performance standards applicable under it;
(b) The right to receive compensation if a standard telephone service is not connected within a specified timeframe;
(c) The right to receive compensation if a fault or service difficulty exists on a standard telephone service and is not rectified within a specified timeframe;
(d) The right to receive compensation if TPG misses an appointment with a customer with whom TPG has made an appointment in connection with the standard telephone service.
The specified timeframes and the amounts of compensation vary based on the customer location, the nature of the infrastructure available at the customer site and the length of time during which default has occurred. Details are available at the ACMA website at http://www.acma.gov.au/WEB/STANDARD/pc=PC_2017
5.3. If you wish to acquire a TPG Home Phone and Landline Rental plan in respect of which TPG requires that the CSG be waived, you must agree to waive the CSG and complete the CSG Waiver Form.
5.4. TPG VOIP may perhaps be a standard telephone service. It is therefore a condition of these plans that you also waive rights to the CSG.
5.5. If you give a CSG waiver and withdraw that waiver within 7 days of giving it, the waiver will not be effective and you agree that we may terminate the agreement for the supply of the TPG Voice Service.
6.1. To use the TPG VOIP service, you must obtain and maintain:

6.5. TPG supports only VOIP Routers which have been purchased from TPG. TPG does not support other VOIP Routers.
6.6. To use the TPG Home Phone and Landline Rental service, you require a telephone handset connected to an available and properly connected qualified copper pair. The supply and maintenance of the telephone handset and the cabling at your premises is your responsibility. TPG is responsible for the copper pair between the exchange and the Network Boundary Point (described in clause 10.6 below).
6.7. If, during the application process, you order equipment from TPG, TPG transfers title to that equipment to you on payment of the purchase price. Risk in the ordered equipment passes to you when the equipment is shipped from the TPG warehouse.

6.9. TPG will only deliver ordered equipment to the service delivery address supplied by you in your application for service. If you are not available to receive delivered equipment and the equipment is returned to us, the cost of the return will be borne by you. In addition, we will charge you to redirect/resend the equipment. Shipping & handling fees are non-refundable.
6.10. Any equipment not supplied directly by TPG is not supported by TPG. TPG will supply basic information about the settings that may be necessary to make unsupported softphone clients, USB Phones IP Phones or VOIP Routers function with the TPG VOIP service but does not warrant that such settings will work and will not provide customer support in relation to unsupported devices. Assistance in relation to unsupported equipment should be sought from the manufacturers or distributors of the equipment.

access to your equipment or software, including equipment or software
provided to you by TPG, to make calls using your TPG VOIP service.
8.2. TPG will provide you with a username and password at the time of activation. It is your responsibility to maintain safe and secure that username and password.

Numbering Plan under the Telecommunications Act 1997 will be allocated
to you for the period during which you acquire the TPG Voice service.
9.2. The geographic number allocated to you will be based on the service delivery address that you nominate in the application process or which you subsequently advise us. The number allocated to you will be at TPG's discretion. TPG has no obligation to give you an alternative number. If you move the service delivery address, TPG may be required to give you a different service number, relevant to your new service delivery address.

(a) completing an online application process at the TPG website;
(b) completing an application form at an authorised TPG dealer; or
(c) ordering the service through a telephone sales consultant.
(b) TPG may rely upon the service delivery address for the service being accurate when it allocates the service number to you.
10.3. Once you have correctly completed the application process, TPG will determine its capability to accept the application and, if it accepts the application, will endeavour to activate the TPG Voice service. If you have any complex services on the copper pair, you will be required to cancel those complex services before installation can proceed.
10.4. By applying for the Service, you authorise TPG to convert the copper pair to a line for use with the TPG Home Phone and Landline Rental service. The telephone line and all services and features associated with the telephone line (including PSTN landline telephone service) will be disconnected automatically once the service is activated. You are responsible for terminating or otherwise managing any contracts or arrangements between you and the existing carrier for supply of services over that copper pair.
10.5. In the case of TPG VOIP, TPG will allocate the service number to you and will inform you that the service is activated. The service will be available for use and you must set up the relevant Connected Computer, softphone, USB Phone, ATA, IP Phone or VOIP Modem to enable use of the VOIP service.
10.6. In the case of TPG Home Phone and Landline Rental, the following process will occur:
(a) TPG will conduct an initial test to ascertain the likelihood of there being a suitable copper pair at the service delivery address.
(b) If the initial test discloses that it is unlikely that a suitable copper pair exists at the service delivery address, TPG will advise you that a service cannot be provided and the application will be rejected.
(c) If the initial test discloses that it is likely that a suitable copper pair exists at the service delivery address, TPG will debit the initial upfront payment under the terms of the plan that you have chosen and will perform a more comprehensive service qualification in relation to the copper pair. If the service qualification establishes that the copper is not suitable, TPG will refund the initial payment and the application for service will be rejected.
(d) If the copper pair is suitable, TPG will endeavour to transfer the copper pair off the existing carrier's equipment and connect that copper pair onto TPG's equipment. When this occurs, all existing services then using the copper pair (including existing telephone or fax service, pay TV, back to base alarm monitoring) will cease to be useable.
(e) TPG will activate the service up to the Network Boundary Point which could be:
(ii) MDF (main distribution frame) - used in apartment blocks, offices or other business premises; or
(iii) Network termination device - a third party carrier’s box externally mounted to single dwellings, individual living units or small business premises.
(g) If you wish to use a new number allocated by TPG, our systems will allocate that number based on the service delivery address details.
(h) We will inform you when the service activation, including porting if applicable, has been completed.
10.7. You must arrange for the appropriate cabling to be installed between your premises and the Network Boundary Point. In particular, this means that you must be present on the nominated day of installation and arrange for jumpering at an MDF in a unit block, if necessary.
10.8. We will endeavour to install the service within a reasonable time from your order but provisioning may be rejected or delayed due to many factors, including but not limited to, transpositioning (the line cannot carry TPG Home Phone and Landline Rental). Such issues are outside of our control. If there are issues, you must give us the opportunity fully to investigate the reasons for such rejections before terminating the contract.
10.9. You are responsible for all costs and charges associated with any agreement for the delivery of carriage services supplied to the service delivery address on the telephone line before the cutover to TPG Home Phone and Landline Rental.

Contract Period is applicable to the service. You agree to retain the
service for that Minimum Contract Period.

11.3. In addition to the rights of termination set out in the Standard Terms or otherwise in this Service Description, we may terminate the service by giving you written notice in the following circumstances:
(a) If you have not used the TPG VOIP service for a period of 3 months;
(b) You use the service to make threatening, abusive or hoax calls; or
(c) You use the TPG Voice service to make calls via another carriage service provider, whether by way of an override code or by preselection.
12. RELOCATION OR CANCELLATION
12.1. You may request us to relocate the service delivery address for
the service. Our ability to accept a relocation request will depend on
the existence of available infrastructure and an appropriate qualified
copper pair at the new service delivery address. If a relocation cannot
be processed because of a lack of infrastructure or a suitable copper
pair, the relocation request will be treated as a cancellation by you
of the service and, if early, may require you to pay the early

13. SERVICE FAULTS
13.1. While we will endeavour to make TPG Voice services available to
customers 24 hours a day, 7 days a week, TPG Voice services are not
fault free and we cannot guarantee uninterrupted service, or the
performance or quality of the service. There are many factors outside
of our control which affect TPG Voice services, such as the performance
of third party suppliers (including overseas telephone companies) and
equipment, force majeure events, for TPG VOIP the amount of bandwidth
available for use by the voice service, and quality of the copper pair.
13.2. TPG limits its liability to you for interruptions to your TPG Voice service or for any resulting damage or loss suffered by you or any third party to a maximum of 12 months charges paid by you to TPG for the TPG Voice service.
13.3. We reserve the right to perform maintenance work from time to time, which may temporarily interrupt your access to the service. Where possible, we will perform this work during non-peak times.
13.4. You must direct all queries regarding faults/outages of the service to our technical support Help Desk (see contact details online at http://www.tpg.com.au/about/contact.php). You must not direct inquiries to third party service providers, including Telstra. We will invoice you for costs incurred by us if you engage a third party for assistance with your service.
13.5. If TPG determines on reasonable grounds that the fault is not related to the TPG infrastructure (for example faulty socket, modem, internal wiring) an Incorrect Callout fee may apply. To find more information please see http://www.tpg.com.au/products_services/homephone_additionalprices.php for TPG Home Phone and http://tpg.com.au/small-office-home-office/additionalpricing.php for TPG Landline Rental.
14.1. You must pay all equipment, delivery and set-up charges in
14.2. You acknowledge that charges will be incurred when the service is used. It is therefore important that you take steps to ensure that such usage does not occur without your authorisation. You should ensure that you are in control of devices that might make use of your services, such as computers, handsets, mobile phones, and wireless devices connected to your service and that third parties cannot access or use such equipment without your authority. You acknowledge that usage of some services can occur because of an infection of your computer with a virus or due to other unauthorised third party intrusions. You should ensure that you have appropriate protection systems operating on your equipment to restrict or limit the possibility of unauthorised usage.
14.3. As TPG is not able to control access or usage of your handsets and other equipment, you are responsible for all usage charges in respect of the use of the service, whether or not such usage was authorised by you, unless the usage was caused by a mistake by TPG.
14.4. The charges for use of the TPG Voice will be in accordance with:
(a) The rates for certain call types or features identified as applicable to the plan you apply for in the application process (the "Specified Rates"); and
(b) The rates for specific features acquired by you after the original application process as nominated to you when you acquire those specific features;
(c) For preselection and all other call types (the "Variable Rates"), the rates set out in the TPG Voice Rate Card available on the TPG Website from time to time which may be separated into Variable Rates for TPG VOIP and Variable Rates for TPG Home Phone and Landline Rental and Variable Rates for Preselection.
14.6. Specified Rates may not be varied by TPG without provision to you of at least 45 days written notice. Because the Variable Rates are:
(a) set low to give you the maximum possible benefit; and
(b) can be significantly affected by currency exchange rate changes and political and commercial shifts in foreign countries
TPG reserves the right to modify the Variable Rates set out in the TPG Voice Rate Card at any time and without individual notice to you. Any changes to the TPG Voice Rate Card will be displayed on the TPG website. Before making a Variable Rate call type, you should check the TPG website to ascertain what rate will apply to that call.
14.7. Other charges that may apply for various events and options are set out in the Additional Pricing page found online at TPG Website (http://tpg.com.au/products_services/homephone_additionalprices.php for TPG Home Phone and http://tpg.com.au/small-office-home-office/additionalpricing.php for TPG Landline Rental).
15.1. For TPG Voice services, TPG requires that all customers pay a
deposit to be held by TPG to apply against any accrued charges. The
deposit amount will be nominated in the application process. If the
deposit falls below a specified amount, TPG will automatically debit
your nominated account/credit card to restore the deposit amount. If
the top up fails, TPG will restrict the service. The amount and
frequency of debit will depend on the usage of the TPG Voice Service.
You authorise TPG to debit your nominated account/credit card in
accordance with those arrangements. TPG will provide you notice about
the restriction event. If the service remains restricted and you fail
to remedy the default within 30 days, TPG may disconnect the service.We
will provide SMS or email notification when debits are made. Where you
have a reasonable claim or dispute with respect to a debited amount, we
will suspend further debiting until a determination on your claim or
dispute has been made. We will reimburse any incorrectly debited amount
as soon as reasonably practicable.
15.2. Payment options are credit card and/or direct debit from a nominated bank account, as specified on the TPG website for the plan chosen by you. Accounts paid with an American Express or Diners Club card will incur a surcharge of 2.75% (incl. GST) of the payment amount when we debit the card.
15.3. Invoices will not be issued but charges will be incurred and payable regardless of the fact that an invoice has not been rendered.
15.4. Where payment is made by direct debit or credit card, TPG may suspend or restrict the service without giving notice to you if the direct debit is declined for any reason. A dishonour fee will also be payable in respect of such a decline. If TPG has attempted incorrectly to debit or has debited an incorrect amount, TPG will waive the dishonour fee and reinstate the service as soon as reasonably practicable.
