Some of you may have read my thread of about a year ago regarding the format of the CallerID on the Woosh phone network. After I complained, they changed it (For the much better). Thru limited exposure to Telecom CallerID in the Hawkes Bay I clearly recall leading zeros being present on incoming calls on both residential POTS connections as well as Basic Rate ISDN setup.

Also here, we have leading zeros on the CallerID at work (Primary Rate ISDN) however I am unsure if we add this in via the PABX (Must find that out).

Does anyone here with CallerID on the Telecom landline get a leading zero on incomming calls. I dont see what advantage not having the leading zero has. The numbers dont match names on the phone books on the phone and returning a missed call becomes a manual task (Write number down, dial manually).

Thought and Comments?

Telecom's network specs are that a 0 should not be included. Remember the 0 is not part of the phone number, merely a network access code.

Yes but the number is of less use to me without the access code. Surely it makes sense to add it, no?

No because all Telepermit devices are programmed to add it.

What length phone number is is receiving? Many devices do have an option in the menu or manual as to whether they should add the extra 0 or not.

The Telepermit specs talk about CID here:


Caller display equipment
(1) Caller display devices which offer a dial-back facility represent a potential difficulty for users. The number forwarded from the network comprises only the area code and the local number, with no leading "0". Wrong numbers will result in MOST cases when such devices dial only the number received. * Without the "0" prefix, the area code is seen by the exchange as the first digit of a local number. The last digit of the true local number is then ignored. The only cases for which the correct number is shown and dialled is where the device is used within a Centrex group.

* See also clause 11.4.5 for further information on number formats.

(2) There are three possible ways to avoid the problem described in (1) above, and one of them should be employed on adjunct caller display units. The possibilities are as follows:-

(a) Dispense with the dial back feature totally.

(b) Provide for digit insertion in accordance with sub-clause (5) below.

(c) Incorporate a keypad for manual insertion of digits.

(3) Telecom pre-sets each line in the local exchange to either "normally display" or "normally withhold" the calling number, as determined by the customer concerned. It should be noted that callers (who may or may not be the actual customer) may wish to control the display of their numbers on a call by call basis as follows:-

(a) To withhold a normally displayed calling number, dial the prefix "0197".

(b) To display a normally withheld calling number, dial the prefix "0196".

(4) Where dialling such prefixes involves the use of an associated CPE device, potential problems may arise, as explained in clause 5.6.4.

(5) Where a dial back feature is provided on an adjunct caller display unit and there is no associated keypad on the unit:-

(a) the digit "0" shall be inserted as the first digit where the number received from the network comprises 8 or 9 digits.

* Local and national calls are indicated by a number length of 8 or 9 digits.

(b) no digits shall be inserted where the number received from the network comprises 7 digits or less.

* Such short numbers indicate either a Centrex call or an incoming international call for which the number is not available.

(6) For international length numbers, an adjunct caller display unit should be capable of storing and/or displaying up to 15 digits. If a dial back feature is provided on such units, the digits "00" should be inserted as the first digits for all cases where the number received from the network comprises 10 or more digits.

* The majority of numbers of this length will, in due course, represent international incoming calls.

* Note that there may be some incoming international calls which result in number lengths of less than 10 digits, but these are expected to be in the minority. Typical examples are those from the Pacific Islands.

(7) Display units providing auto dial back facilities may also provide the following facilities:-

(a) For dialling local numbers, a device may be programmed to automatically delete the "0" prefix and area code digit and dial only the 7 digits of the local number.

* It should be noted that every area code used in the Telecom PSTN serves more than one local calling area. Any dial back logic will thus need to examine the one digit area code and one or more digits of the following 7-digit number in order to accurately determine whether the number received from the network relates to a local call. Since the digits indicating local calls vary from area to area, this arrangement is likely to be practicable only for Computer-Telephony Integration (CTI) systems.

(b) Where an exchange line access prefix is necessary, the device may be programmed to automatically insert it. In such cases, the access prefix must only be inserted for local and national calls, and not for calls internal to a Centrex group or PABX network.

* To avoid any customer misunderstanding, it is recommended that suppliers clearly state in the product brochures whether or not the product is "Centrex compatible". Return to Contents

Is this using a standard Telecom landline? Does your phone have a Telepermit? Maybe you should ring Uniden and ask them why their device appears to have non correct firmware for the NZ market. My Uniden here adds a 0 correctly on 8 and 9 digit length numbers. The only issue I can see arising is the Telepermit specs don't include 10 digit numbers in this so a Vodafone 8 digit 021 number may not function correctly with some devices.

Yep its a standard Telecom Residential landline, connected to the Courtney Place exchange here in Wellington. Both the Uniden and the Brother were purchased at Noel Leeming in Feb 06 and both carry NZ Telepermit.

The uniden gives me the option of adding zero to everything, which is no good as if I want to make a local call, it adds a zero in front, even for manual dialing.

With telecom local call still goes through with 0 in front and don't get charged. My Uniden adds 0 to number and I had no problems dialing locally with the 0. Did get charged when had tolls go through another network provider a few years ago.

Mine doesn't do it for manual dial though, if it does that then dialing your area code with the number should work ok.

If i want to make a local call with this feature on in the phone I would have to add a 4 in front if the number, and then as we have Call Track on the line I would have to enter my pin number. (It still promts for pin even though the call may not be charged for...i've tested it)

Thats alot of pain the ... just for making a local call.
