Why I Can't Dial Certain Access Numbers

There could be three reasons for getting an unobtainable tone:

i) Other operators like NTL, Telewest and mobile providers may need to open up our access numbers. To speed this process up contact your service provider, tell them the access number you wish to call and ask if you can open up the telephone number.

ii) You might be barred from calling 09 numbers. Please contact your service provider to have the bar lifted.

iii) Some Indirect Access providers like Onetel do not allow calls to some or all of our access numbers. If you normally dial an Indirect Access code before your calls (for example 1833 for Alpha Telecom or 1877 for Onetel) you simply omit this code and dial the just-dial access number directly. Omitting the Indirect Access code means the iust-dial call will be charged by your line provider (usually BT). If you are using a Onetel PhonePal you can either unplug the PhonePal or dial 1-2-1 to bypass it. Should you have chosen the Onetel 'Select' option we would advise to contact Onetel to provide you with a code to override this feature.
