Phone number format
Considering the people hub in WP and W8 and Live contacts (contacts.live.com), Windows Live (web) and Windows 8 needs a feature under settings:
Settings > General Settings > Phone format
1- +xy (xyz) xyz-xyzx
3- +xy xyz xyz xyzx
... where Option 1 can be interpreted as:
If country is selected or country code is present, then:
e.g. +1 (856) 792-1432
e.g. (856) 792-1432
Each segment after operator prefix has no more than 4 digits and number of digits in latter segment >= that in former segment..and since so forth.
On save, the settings must be sync and applied in all metro, phone (dialer's incoming/outgoing and people hub), and windows live web applications.
Also, the phone dialler app should have the cursor and copy/paste option and it should accept the alphanumeric characters. Let's say +1-800-Microsoft should be translated as: +1-800-6-4276-7638 the letter-to-number translation is required via the following system:
0 = none (in some older telephones, OQ or OQZ)
1 = none (in some older telephones, QZ)
2 = ABC
3 = DEF
4 = GHI
5 = JKL
6 = MNO
7 = PQRS
8 = TUV
9 = WXYZ
If the phone number is dialled or saved with specific format (alphanumeric and/or with decorators like: ( ), SPACE, +, -), the app should respect the format and next time it should display it the same way.
Thanks for listening.
