Paul:
Eircom always automatically announces numbers with a pause / stressed number at each block of nos.
They seem to have dropped announcing "double-zero" etc. I guess it could confuse non-native English speakers and complicates things generally.
the format here is :
5-digit: 099 22 222 (Being phased out)
6-digit: 099 222 222 (Being phased out)
or 7-digit: 099 222 2222
8-digit is only used for voicemail by prefixing the no with 5 so it's written as 099 5 222 2222
There are also a few non-standard area codes left.
01 - Dublin (takes in more than 1/3 of the countrys population!)
and a few 0X0X codes (all gone this year)
No idea what, if anything, will be done with Dublin's code. I think it will be changed to 03X as it runs out of numbering space.
They also suggest that you don't put the area code in brackets anymore as for years it has made no difference wheather you dial it or omit it in you own area.
