[cisco-voip] Singapore International Dialling

[Amit Kumar]

Hi,

Does singtel needs 001 as international prefix. As usually except US most
telco either use digit to classify calls or TON or plan settings like:

Type ISDN and plan international.

Would be good to clarify with singtel first.

Thanks,
Amit
