 The Business Phone Blog



With the roll out of the NBN, the way Business Phone Lines operate will change for the majority of business in Australia. The copper used for PSTN phone lines will be eventually cut off and will need to be replaced with an alternate technology. So what are the Business Phone Line options?

There are 4 options currently available. 3 using VoIP and 1 using ISDN (which will still be carried on Telstra copper) with VoIP generally being the cheaper option for monthly running costs. Here's a brief run down on the 3 options in no particular order.

1. ISDN 2 OR ISDN 102030

ISDN services will still run over Telstra copper. That copper wont be disconnected as ISDN phone lines are declared a protected special service. ISDN 2 has 2 Lines per service and ISDN 102030 has increments of 10, 20 or 30 lines. ISDN2 can be ordered in multiples giving the user access to 2/4/6/8 lines or more. Many business currently have ISDN 2 or ISDN102030 and wont need to make any changes when the NBN is delivered. However if your business currently has standard PSTN phone lines, you may choose to convert your existing PSTN Lines to ISDN 2 and convert your PBX Phone System to carry an ISDN service. This will allow business to keep their numbers on a tried and true technology on Telstra network but it will be more expensive than the VoIP alternatives. Standard PSTN phone numbers cannot be ported to Telstra ISDN 10/20/30 but can be ported to the Optus ISDN 10 equivalent, MultiLine. Rental for an ISDN 2 is $70 per month (2 lines) and and ISDN 10 is $250 (10 lines).


Hosted PBX is a VoIP Phone System where there is no box for the phone system. The System is Hosted in the Cloud. The only equipment on site are the handsets and the Switch. Monthly rental is charged per handset and is typically around $10 per month per handset. Many business find a Hosted PBX provides an economical and cost effective solution for a new phone system and is particularly suited to SMEs.  


SIP Trunks are a business grade VoIP service that are installed onto a standard or traditional PBX Phone system. To use SIP trunks you need a SIP compatible Phone System. Many PBX Phone systems under 10 years old are SIP compatible or can be modified to use SIP Trunks by installing an IP card or connecting an ATA (Analogue Telephone Adapter) to their Phone System. Your existing phone numbers can be ported to SIP. SIP trunk rental is around $10 per month.

SIP trunks are also beneficial where the number of handsets outweighs the number of calls needed to be made at any time. eg If you have 15 or 20 handsets but only need to be making 6 calls at any one time you would only need 6 SIP trunks.   


The NBN Network Termination Unit (NTU) has 2 Voice Ports called UniV ports (vs UNi D ports for the data ports) on the NTD. The UniV Ports are a built in ATA as described above bit business is limited to a maximum of 2 ports and call rates are restricted to the carriers call rates which can be expensive...Usually a lot more expensive and than using SIP trunks and without the added features of Hosted PBX so even a business with only 2 lines can be significantly better off using Hosted PBX or SIP Trunks.

We have a wide range of PBX Phone Systems options for our Melbourne based customers and thought now would be a good time to list the options and brands we have available. All the systems now have a broad range of features that make it difficult to separate them on any thing other than price. While we do Phone Systems Australia wide, being Melbourne & Sydney based gives us a few extra options in those locations.


We use Cisco Hosted PBX handsets because of their Auto Config feature. We can plug the pre configured handsets to the internet on site and once they connect to our servers and Auto connect. They offer a fantastic range of features and benefits for most business. We use Cisco handsets for Hosted Voice only and they are the first choice for NBN Sites.


The great advantage with the Yeastar MyPBX systems is that they can use a range of services. PSTN, ISDN 2, ISDN 102030 and SIP Trunks can all run over these systems giving a impressive range of redundancy options. We are finding these very popular in NBN roll out areas...the NBN is not quite there so customers connect using existing PSTN or ISDN services and switch to SIP Trunks when the NBN arrives. A very cost effective solution.


The Avayas PBX Systems are proving to be very popular mid priced systems. We have primarily been installing Avaya Phone Systems in sites with 4-10 handsets using PSTN or ISDN 2 services. An Australia wide support base for Alcatel PBX Systems provides peace of mind.


From our perspective the Alcatel PBX Systems are the Gold Standard but as with most quality products tend to be a bit higher in the price scale. Again fully featured with an Australian wide support base. We tend to be putting these systems into sites with 8+ handsets over ISDN 2 or ISDN 102030.


LG Nortel iPecs seem to be the Telstra TBS of choice. They are also at the higher end of the price scale.


The Samsung Phone Systems are very popular due to their range of features. They split the middle with pricing in that the lower end Systems for 2-8 handsets can be cost effective but larger systems seem to be at the higher end of pricing.

The NBN is coming and you don't know what to do about your PBX Phone System. Do you need to replace the Phone System? Can the Phone System be modified? What do you do?

One things is clear, unless you have a IP Phone System running VoIP or SIP Trunks, there is no do nothing option. One thing to understand is that once the NBN Copper cut off comes along, most business phone calls will be carried over SIP trunks which are a business grade VoIP service. These are usually a lot cheaper to run than services over the Telstra copper. However make sure you do get good informed advice. We are hearing lots of stories from uneducated sales people at Telstra Business Centres telling customers their phone systems have to be replaced. That's not always true and here are the options.

What are NBN Phone System choices?

1. Add an IP Card to your existing phone system.

An IP card is hardware that allows your Phone System to run SIP Trunks or VoIP over your existing Phone System. Some systems may already have an IP card embedded so for this option we need to get a PBX maintainer to your site to have a look at your System and provide a quote to upgrade. Most quotes we have seen to do this range between $1000 and $2500 depending on the Phone System. There are some older systems this will not be an option....the IP hardware either doesn't exists or is no longer available.

2. Add an Analogue Telephone Adapter (ATA) to your existing phone system.

An ATA is an external device that does the same job as an IP card, but its not installed internally into the phone system. It comes with its own box and sits outside of the system. Its a bit like a digital Set Top Box for your Phone System. The ATA converts a SIP Trunk to an Analogue signal and connects to the PBX typically via standard phone cable. An installer is required to connect the device and for some PBX systems they can be problematic to configure initally (as you are adding another device to the chain of systems) but once working correctly, generally don't have too many issues. The cost to do these conversions will depend on how many lines you have/need bit will start at about $600 for 4 lines and around $1000 installed for 8 lines.

3. Convert your existing PBX to ISDN or purchase a NBN ready ISDN Phone System.

ISDN 2 and ISDN 102030 services run over Telstra copper but are exempt from the copper cut off. To convert your PBX to ISDN a BRI (Basic Rate Interface) or PRI ( Primary Rate Interface) card would need to be installed on the Phone System. The cost to do this will again depend on your system but typically $1000-$2500 with some PBX systems costing more. Again there are older systems where the cards are no longer available. The benefit of using ISDN is that it a very stable product. The cost of ISDN 2 & ISDN 102030 services have started to drop as Telstra realizes they need to lower prices to compete with SIP Trunks. Our call rates on ISDN are not dramatically different to our SIP trunk call rates.

New ISDN Phone Systems start at around $2000 with 4 handsets.

4. Install a new Hosted PBX Phone System or NBN Phone System.

Hosted PBX Phone Systems are a cost effective option typically working out at around $250-$350 per handset installed. With a Hosted or Virtual system that runs entirely over the internet, the only hardware on site is the handsets and a switch. With a Hosted PBX there is no PBX unit on the wall as with traditional phone systems, and this can be where significant savings can be made. There is a range of features and benefits on a Hosted PBX that can dramatically improve the efficiency of a business. With Hosted PBX the line rental is usually based on the number of handsets as each handset has a license of around $10 per handset per month, which is instead of the Telstra Line rental. Hosted PBX systems can also be run over ADSL in the lead up to the NBN roll out. These are a far more cost effective option than Telstra DOT Digital Office Technology Phone Systems.

5. Install a Hybrid IP Phone System

A Hybrid Phone System (eg our YeaStar MYPBX Phone Systems) is a Phone System  that can run PSTN Phone lines, ISDN Phone lines and SIP trunks. These are advantageous at larger sites where there is many handsets. Instead of paying a monthly license per handset, SIP trunks can be installed based on the number of calls required, not the number of handsets at the site. Eg 30 Handsets but only 10 SIP trunks. The big advantage of these systems in NBN roll out areas, is they can be installed immediately using existing PSTN or ISDN Phone Lines and then convert to SIP trunks when ready. The conversion to SIP trunks can be done remotely saving on expensive technician call out charges. The Yeastar MyPBX Systems with 4 PSTN or 4 ISDN lines start at around $2000 with 4 handsets. If no PSTN or ISDN is required they start at around $1600. Again these are far more cost effective option than a Telstra TBS phone system.


Whatever you decide to do our advice is to act early. Don't leave it till the last month when the cooper cut off is imminent and risk having your business phone lines out of action. Speak to an expert and have a plan in place. It doesn't mean you need to commit immediately but have a plan in place for transitioning your phone system to the NBN.




Our SHDSL promo has been extended till the end of June (Very happy face) with the 10/10 Services being $419 per month and the 20/20mbps services being $479 per month with free installation on 14month agreement. Even better news is that the sites that don't quite get to 20/20 Mbps can get better pricing.

  • 12/12 Mbps SHDSL $479
  • 14/14 Mbps SHDSL $479
  • 16/16 Mbps SHDSL $479
  • 18/18 Mbps SHDSL $479
  • 20/20 Mbps SHDSL $479

Previously unless the site qualified for the full 20/20 service, (eg the site test qualifies only up to 18/18 Mbps)  the option was to take a 10/10 or pay the substantially higher standard pricing on 18/18 Mbps services. Standard pricing on 18/18mbps was $789 while a 12/12 was $659 so the price reductions are significant.

Take advantage of our special offer. Sign up for a SHDSL 12-20Mbps between now and 26 June and get Free install and 1 Month free. Click the button below to speak to an Australian based expert. You must mention this advert to take advantage of the promotion.




We have seen a recent increase in interest in ISDN 2 services from Business located in NBN roll out areas! Why?

Well feedback has been that many business still do not want to rely on a VoIP or Hosted Phone System. They want the reliability of ISDN 2 and are prepared to pay a bit more to have it. Compared to Telstra DOT or SIP trunks over the NBN ISDN 2 is definitely more reliable. Because the ISDN2 is a protected service its no going to get cut off like a PSTN line would.

While not carrying as many features as a IP Phone System, ISDN 2 still has its share of functionality. Combined with Free ISDN 2 Installation, using ISDN can be a compelling argument. Read on below to find some of the features on ISDN 2.



With Call Control, you can turn the selected barring level/s on and off as often as you require. In this section, provide the barring level/s which you require to be active with Call Control turned on. A Personal Identification Pin (PIN) will be provided by Telaustralia and is required to activate and deactivate Call Control.


In the normal service configuration the calling line identification (calling number) is sent forward with each call and is presented to a called party who subscribes to Calling Line Identification Presentation or Calling Number Display.  The sending forward of the CLI can be blocked on a call by call basis from some CE.
Alternatively, you may have the service configured to prevent the forwarding of CLI. In this configuration the sending forward of CLI on a call by call basis can be initiated by some CE. This configuration is Calling Line Identification Restriction (CLIR).  Please check with your CE supplier to confirm how you can both allow and restrict presentation of your telephone number. Calling Line Identification allows the telephone number of the caller to be presented on most incoming calls; unless this has been restricted by the caller.


This feature informs you when another caller is trying to get through to you while you are using the full capacity of your service (both B channels). It enables you to take the incoming call and place one channel on hold.   


1. With Call Forward Immediate, you can forward your calls to a number you select and change it at any time. Your calls will be forwarded immediately. 2. With Call Forward Busy, your calls will be forwarded to the number you select if your phone is busy. 3. With Call Forward No Answer, your calls will be forwarded to the number you select if your phone is not answered within 20 seconds. You can change the time delay from 5-60 seconds Fixed Options Fixed number forwarding means you can forward to a previously selected number stored in the telephone exchange. In this section you must nominate the number to which the calls are to be forwarded and whether you wish this to occur for Immediate, Busy or No Answer options.


With Enquiry /Conference, you can make another (enquiry) call to a third person when you are already on a call. If you with, you can then have a three-way conversation (conference).   Section 12 - Activated Call Redirection - All service types excluding DID Pt to Multi Pt This feature is a permanent activated redirection. This is typically applied where a customer is unable to activate call forward from their CE and requires call forward on their active ISDN service (eg forward on busy). This feature is applied as a call forward fixed and applied by Telaustralia. Note: This is not a disaster recovery redirection and cannot be activated within a short time frame (activation of this feature may take up to 5 days). There are other options available for disaster recovery redirection.


Call Transfer allows the ISDN2 customer to transfer an established voice call to any other number (ie fixed or mobile) anywhere in Australia or overseas. The ISDN 2 customer pays standard ISDN 2 call costs for the successfully transferred leg of the call. Call Transfer feature rental charges apply. Subscription to the Call Transfer feature automatically includes the Enquiry / Conference  feature. 


This feature allows you to activate the recording of the caller’s telephone number of a current call. The call details are recorded at the Telstra exchange and used by Telstra to identify the service from which the offending call/s are generated.  If necessary, Telstra will involve the police. Prior to July 2001, this feature has been provided to all ISDN services as Malicious Call Trace (MCT), a non-ETSI feature. ETSI compliant MCID is now available and is functionally identical to MCT.  Customers subscribing to this feature will be provided with Malicious Call Trace as well as Malicious Caller Identification (as the capability of CE to handle each version may differ). Subscription to MCID/MCT will apply the feature per access for Multi Number services; on all accesses for Line Hunt services with Multi Number and across the whole number range for DID services. Please consult your CE supplier if you plan to use this feature.  Extra charges apply for this supplementary feature.  


All service types excluding DID Pt to Multi This feature allows you to send and receive from another user, information in packets of 128 Octets each. There are two types of User to User messaging available:   • User to User 1 : Where information is only sent between users during call establishment and clear down • User to User 3: Where information is only sent between users during the active part of the call. This feature is not supported on international calls. Please consult your CE supplier if you plan to use this feature. Extra charges apply for this supplementary feature.  


Only available on DID Pt to Pt / Not compatible on DID Pt to Multi Pt The feature allows you to receive details of call costs for each of your extensions. On your account you will receive a listing of the extension numbers and a list of the calls made from each extension with start time, duration, indication whether voice or data call, cost, called number, destination and rate. The feature is applied across the entire allocated range, and is not applied to individual extensions in isolation.  Extra charges apply for this supplementary feature.  


Only on DID Pt to Pt/Not compatible on DID Pt to Multi Pt This feature allows you to redirect all incoming national reverse charge calls and all international operator . connected calls to a nominated number (which will generally be an operator console). This assists you to prevent the acceptance of unauthorised incoming calls. The diversion of calls can not be guaranteed in cases of interconnection with another carrier (particularly international) where specifications may not align with those of Telstra. Extra charges apply for this supplementary feature  


The Direct Indial option allows your customers to call your staff direct without the need to go through an . operator and is available in blocks of 100 numbers only. Configuration Setting The majority of Direct Indial services should be set to the default setting of point to point operation which is the standard setting for most PABXs.  Only tick the “Yes” box if your equipment supplier specifically advises you that point to multipoint configuration is required  


The majority of ISDN Individual Number services should be set to the default setting of point to multipoint operation which is the standard setting for most Routers, Terminal Adaptors & PC Cards. Most PABX and Telephone Systems have a setting of point to point operation. Only tick the “Yes” box if your equipment supplier specifically advises you that point to multipoint configuration.  


If you have more than one ISDN 2 service it is possible to group the services so that incoming calls hunt across the available access lines to find a free line. This feature is called Line Hunt and is activated on incoming calls made to a Group Directory Number.

Over the years, we have seen customers spend enormous amounts on PBX Phone Systems. Customers wanting Telstra ISDN 102030 or Optus Multi Line are faced with the cost of the ISDN Primary Rate Interface Card (PRI Card that enables a Phone System to connect to an ISDN 102030) in many cases being around $2000 for the card alone, plus additional license fees and installation costs.

We were pleasantly surprised when we started selling Yeastar MyPBX systems to find that many of the reasonably priced Yeastar MyPBX Phone Systems have embedded PRI cards with system prices including the PRI card starting at around $2900. These Systems also have built in PBX system features that would see the traditional providers charging many $thousands more.

The MyPBX U300 retails for $2900 and includes embedded PRI up to 30 channels, No Limit SIP Trunks, up to 300 Extensions, 50 concurrent calls and built in Auto Attendant, Voice Mail to Email and Unified Messaging. Amazing value.

That the ISDN 102030 is at this stage not going to be effected by the NBN rollout and the Systems SIP capacity, makes these systems 100% future proof.

Combined with Yealink T40 series this is seriously great value. If you are looking for a new PRI ISDN 102030 PBX Phone System with a view to future proofing your business click the link or give us a call on 1300783528.




At this stage there is no indication that ISDN 2 or ISDN 102030 services will be effected at all by the NBN. They are currently protected special services and are not included in the Copper Cut off that will eventually effect all Copper PSTN lines.

This then leads to the fact that ISDN 2 or ISDN 102030 services may be a better alternative for some business facing the NBN copper cut off. Many business are still very nervous about having to move to Hosted PBX or SIP services (Business VoIP) preferring the reliability of copper based services and ISDN gives them that option.

Recent price reductions on ISDN mean, ISDN is now a viable alternative for sites that are facing a copper cut off. Installing a PRI or BRI ISDN card into an existing phone system in many cases becomes far more cost effective than replacing the system or installing an IP card. For many older systems there is no such thing as an IP card but ISDN Cards are readily available. So instead of having to replace the PBX Phone system and handsets outright with a IP system, it may be cheaper to install an ISDN card and transfer their existing PSTN numbers to ISDN 2.

One job we did recently at Pottsville near Byron Bay, the client had 23 handsets on an old Samsung PBX and 6 PSTN lines. They are in a NBN roll out area (still some time away) and were advised by several suppliers including the biggest one, they would need to replace their PBX system and do significant rewiring of the site. These cost to replace and rewire was around $11000. Alternately they had been quoted over $4000 to convert the system to IP and add in the required cabling.

We arranged installation of BRI cards and installed 3 X ISDN 2 services. The capital cost was $1700 and their monthly phone bill dropped by around $150 a month as well. When they NBN comes all they will do is get a new Internet connection and their phones will remain as is.

If you would like to talk to an Australian based professional about what do do when the NBN is rolling out in your area, or changing your existing ISDN services to Telaustralia please call us on 1300783528 or click this button and we will contact you!
