standard dialable number format (c++ tapi)

I want to programatically make calls on a windows mobile device using standard c++ TAPI lineMakeCall function. The phone number (null-terminated) must be in the "standard dialable number format".

There is a function lineTranslateAddress which should make the conversion to the dialable format.

I am testing my application 开发者_运维问答and if I use a nonformated string (ex: 0728000000, valid for my country), this number is dialed but not recognized (The dialing screen shows: Dialing: Unknown).

I cannot find much information about this standard format. Does anyone know something about this format, how it should look, or is it secret?

Help please,

Thanks,

Here is the MSDN documentation page describing this format: Dialable Addresses
