Hi All,

I am doing a research and hoping you guys can help me. I would like to get information about responses when dialing one of three digits first (0,1 and 9). My goal is to identify if there is any dialtone or voice response. I am only interested in NZ fixed line providers published in NZ Connections (http://www.nzconnections.net.nz/Telephone_Service_Providers).

If you use any of the providers below, please reply when you get when dialing these digits. Here is the list of possible answers: "No Dialtone", "Dialtone", Busy Signal", "Voice Response", "Other - specify".

Here is an example for a phone company XYZ:
| When I dial | I get |
0 - No Dialtone
1 - Dialtone
9 - Voice (instructing to dial other numbers).

The providers I am intersted in are listed below.
Thanks for your help!

To make things easier, it may help you to know

0 - is the prefix for all calls to a different region within New Zealand, and for mobile phones. Eg, Calling Auckland from Wellington would be 09 xxx xxxx or calling a Vodafone mobile, 021 etc.
1 - Mainly, our emergency number 111 (same as 911 in the US). Also used for operator calls, eg 123 or 126 to contact Telecom for assistance.
9 - standard number for calling. Eg 9xx xxxx will primarily be for calls to TelstraClear customers when dialled from within Wellington. But, as we have number portability, and others who use 9 as their first digit it could be anyone you are calling.

I hope that helps.

Thanks for your replay. To confirm, when you jist dial 0 or 1, you will not get a dial tone from ANY NZ PROVIDER. Correct?

When you dial 9 (and nothing else), outside Wellington, will you get any dialtone/busy signal/voice? Also withing Willington, dialing 9 will get NO DIAL TONE.

Is this correct?

Hi there..

What is the point of this? What use is knowing this information to you? How is this information going to be used?

for example on Telecom.
pick up the phone and you have dialtone
dial 0,1 or 9 dialtone will go away waiting for the rest of the digits to be dialed.
after 10 secs if you haven't dialed the full number you will get beep-beep-beep-beep sound and then after about 40 secs you will get silence.

On Orcon (LLU Landlines) I think its similar if I remember right but after the long period instead of silence you get a howler tone.

Saying all this .. I would have thought most countries are very similar.

I was merely providing examples.

As per LennonNZ most, if not all of the providers, will accept the 0,1 and 9 and then wait for you to complete the number.

What are you actually trying to establish? There doesn't seem to be any valid point in this.

Dial any single number on a PSTN line in NZ and you won't get dial tone only on a PBX system..  Your not thinking of Voicemail hacking are you??

As said before 0, 1, 9 are not special codes, like in the U.S.

0 is the prefix that indicates an area.
1 means nothing. It's just the first digit in three digit short codes
9 is just the first digit on in a seven digit phone number, usually assigned to TesltraClear but with number portability it means nothing.

Seeing it seems you are from the U.S. I'd say you are creating a product or trying to fix a problem someone found in your product... If the first, cool. If the second, then your client doesn't know you have a broken product and don't know how to fix it.

Which one?

Okay, let me explain. I am my colleagues are working on a medical device that connects to a server using internal modem. This device is intended for elder people, so it is going to be used for their homes. The software uses an automated algorithm that detects a dial tone, instead of asking a user. The device could be used in offices as well, so the algorithm checks it we can get an outside line by dialing 0, 1 or 9. The problem we've seen in some other countries, is that sometimes when one of these numbers is dialed, there is a response that could be mistaken as valid dial tone.

We are trying to prevent this for New Zealand.
Hope this helps!

Go Hawks!

As per LennonNZ and sbiddle - the question seems rather odd, with the goal being strange for someone hosted in the USA.

One might be forgiven for passing you off as a digital equivalent of a train spotter (albeit with a load of photos of phone booths ala 2600 magazine ...)

If you are making a device to interact with the analogue phone lines in New Zealand you will need to visit this website and ensure you get the telepermit "green tick" before you can even connect to the phone line -> http://www.telepermit.co.nz/

Yes, I am from the U.S. as I indicated in my first post. I also had a thread before on this forum so you can check it out.

Our main concern is that there could be some phone companies (that we aware of in Europe) in NZ that provide voice response or undocumented response after dialing these digits.

1 is the escape digit from Centrex or PABX but you may not get a second dial tone. Some systems may require a valid number to be dialled in addition before forwarding the call.

I would be more worried about your device using an analogue modem over a voip connection. Who cares what 0,1 and 9 will do, if it cannot dial out in the first place.

In which case if you are directly connected to the PSTN you will hear a dialtone, and can dial 0, 1 or 9 - no other dial tone will be presented as these numbers have no special meaning on the PSTN. If the line is on a PBX then it's a different story.

VOIP is not a concern since the it takes an analogue signal from the phone line. We've tested the device with VOIP systems and it works fine. The issue we are seeing when the analogue modem thinks it gets a dail tone, when it is actually not a dial tone.
