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,
