Although this information has been on the forum for some 8 months now, I have just discovered some more about this service which is worth sharing with members.
Firstly, my post immediately above is now incorrect about needing to dial 010 at the prompt: you don't !
( This may be a recent change in the service. )
Secondly, another change is that you DON'T now dial the number you wish to reach in full international format, unlike just about any other callthrough I have used before !
The procedure now is to dial the following in this order:-
Their access number
0081 3 4580 0235;
When it answers, dial
2 for instructions in English;
THEN dial your
country code, without 2 leading zeros, followed by your number.
For example, to dial the new Irish callthrough ( which seems to connect during Irish peak times ! ) input 353 700 xxxxxx.
HTH.
