Hi all

I'm trying to put together dial plans for Asterisk and some SIP phones at work. I've got everything else all sorted out, but I'm uncertain on the rules regarding the lengths of 021 and 025 numbers, and can't find anything authoritative online.

So far I have this for 021: 021[3-9]xxxxx|021[12]xxxxxx|0210[3-9]xxxxx|0210[12]xxxxxxx
... and this for the few 025 numbers still around: 025[3-9]xxxxx|0252xxxxxx

ie, for the 021s, six digit numbers for 021s starting with a 3 to a 9, seven digits for 021s starting with 03-09, 1 or 2, and eight digits for 021-01xxxxxx and 021-02xxxxxx. Have I guessed this right?

Thanks,

Andrew

Hi Andrew,

here is an up to date list of the 021 range, I would add a default rule at the bottom something like "021." as new ranges are introduced from time to time. I should also point out that I haven't actually used this on Asterisk/trixbox as yet, but do use this same info for commercial PBX's that I look after.

Cheers

DB

Hmmm. My number (0213XXXXX) wouldn't be covered in this list?

well spotted. Darned spreadsheets. I will post an update shortly.

The error was caused by working with the 'true' prefix of 21 as opposed to 021, this meant my spreadsheet miscalculated the number of X's required. You can of course condense down this list by matches such as N.

021022XXXXX
021023XXXXX
021024XXXXX
021025XXXXX
021026XXXXX
021027XXXXX
021028XXXXX
021029XXXXX

(above can be condensed down to 02102NXXXXX as an example)

02103XXXXX
02104XXXXX
02105XXXXX
02106XXXXX

Thanks :)

Are there exceptions to these rules about? I know someone whose number is 021935xxx!

Why do Voda make things so complicated? 021 is the only number range I know of that is this complicated.

And wait for when all mobile numbers should be eight digits long. I heard TelstraClear is the first one to come with eight digits from the start...

Why Vodafone when they took over Bell South didn't make all their mobile numbers 7 digits is beyond me. Now we all in the PBX world have this crappy 021 mix of number lengths from 6 to 9+ digits that make ARS tables a nitemare. At least Telecom and TelstraClear both have a uniform number length of 7 digits....

It comes from the old days where 6 digit was more than enough. The advantage Telecom has is they changed the whole 025 network to 027 creating the 7 digit plan then.

Chorus has spent $1.4 billion on making their xDSL broadband network faster and even more now as they are upgrading their rural Conklins. If your still stuck on ADSL or VDSL, why not spend $195 on a master filter install to make sure you are getting the most out of your connection?

I personally like my 021 9xx xxx mobile number because it is short and easy to remember. I would be quite upset if vodafone made my change my number to an 021 + 7 or 8.

I wonder if when Telecom bring out their GSM network if there will be a new prefix for that, and if so what the number length would be. I suppose with number portability now tho they will never be able to get rid of some of the existing numbers.
