Hi! I'm new to the forums here, so please let me know if my etiquette is wrong :)  I've had an interest in telecommunications just about forever so this thing peaked my curiosity, and I couldn't find any explanations anywhere for it so I thought this forum would be a good place to start.

 

 

 

I stumbled across an unusual telephone number "prefix" I guess it would be called, and was wondering if anyone (possibly someone who has experience in this?) could explain what's going on?  

 

 

 

Just out of curiosity, I dialed an old number of a house I used to live at, which got disconnected when we left.  Usually I had only dialed this without the 09 area code, and it would answer with an automated message, "You have called 0, 9, 4, 1, 2,..... this number is not currently active", however today I tried dialing it with the area code 09 in front and it read out a completely different number: "You have called 0, 8, 3, 4, 9, 6, 9, 4, 1, 2,........." ..........that had me really confused. 

 

 

 

What could the number 083496 have to do with anything? (the number 9 between that and the phone number turns out to be the area code)

 

 

 

So as an experiment I tried dialing some numbers but adding this number to the front.  (EG for the number 09-123-4567 you would dial 083496-9-123-4567)  And it turns out that you can put that number before any phone number, from any phone or mobile (this includes cellphones, EG 08346-21-123-4567) and it will work...  Note that it takes around 15 seconds to start dialing, with a lot of "pops" and other sounds suggesting connections being made.

 

 

 

So what's going on?  Is my call being routed though a particular exchange?  Is it being measured somehow?  Applying some unknown significance?  08346 is a fairly random number (I'm guessing) so are there more of these "mystery" numbers, and do they mean anything?

 

 

 

Sorry for the huge amount of questions but I find this really fascinating - your answers are much appreciated :)

Found this thread from 2005

 

But my first thought is, 08 seems to be used for automated services / equipment. An example of this is 083210 is used for Voicemail on Spark, to check your voicemail you can call it. Your account on the is set to divert the call to 083210 when it is not answered, which lets people record voicemails to you.

 

In the older days, Dial up numbers for various ISP's started with 08

Will be interesting if someone here knows!

Thanks Yabanize for your response - looking at it, it is definitely one of those numbers, I do remember now the dial-up number being along the lines of 087 or maybe 086...  083xxx numbers are for voice services and the "intelligent network" according to that thread, and that makes sense, seeing as when you dial an inactive number it forwards the call on to an automated message service to tell you that the number's inactive.  Having it read out the 083496 before the phone number, and being an acceptable prefix to any phone number is quite fascinating, I would be interested to understand the workings behind that...

That's a very useful link, will be bookmarking it - however it doesn't describe the 083 numbers any more than "Voice services", which is a bit ambiguous seeing as telephone systems have a whole lot of different meanings for "voice"... 

 

 

 

Based on this, I'm guessing there must be a lot of other 083xxx numbers which are for internal use - does anyone know of a list, or do they try keeping these things unlisted, like they do with exchange locations?
