International Direct Dialling and VoIP Services
The generic international call prefix when making an international call is 000, which all telecommunications service providers are required to share. However, the code is not well known as carrier-specific access codes are generally used, such as 001 for SingTel, 002 for M1 and 008 for StarHub. On a mobile phone, a plus sign (+) can be keyed in as a substitute for the prefix.
VoIP services, like Zone 1511, use prefixes in the 15xx range. For example, to call a number in London using Zone 1511, a subscriber would dial 1511 44 20 xxxx xxxx. hhAccess codes in the 0xx range (e.g. 018 - StarHub's VoIP services or 019 - SingTel's VoIP services) indicate a Tier 1 VoIP provider. Access codes like 1xxx (e.g. 1511) are indicative of a Tier 2 VoIP provider.

Famous quotes containing the words direct and/or services:
“As for your friend, my prospective reader, I hope he ignores Fort Sumter, and “Old Abe,” and all that; for that is just the most fatal, and, indeed, the only fatal weapon you can direct against evil ever; for, as long as you know of it, you are particeps criminis. What business have you, if you are an “angel of light,” to be pondering over the deeds of darkness, reading the New York Herald, and the like.”
—Henry David Thoreau (1817–1862)
“It seems I impregnated Marge
So I do rather feel, by and large,
Some cash should be tendered
For services rendered,
But I can’t quite decide what to charge.”
—Anonymous.
