Hi,
In the Active Directory User Object what format should the phone numbers be to ensure Outlook and Microsoft Lync are able to dial all local and international numbers ?  Regardless of user location / country ?

Is it the full international format that Outlook uses ? i.e.
A US number should be:
+1 (636) 722-3437

An Australian number should be :
+61 (2) 9466-3814

Conform to E.164 formatting and you will be fine. Separators are a personal preference, andnseveral are in the e.164 spec. Use what you are comfortable with.

But always use e.164. Don't add country routing, or trim country codes themselves. ise normalization rules in the dialer for that instead.

E.164 is an ITU standard so their website is a good start. Specific formatting is rather vague (see e.123 for that) so i'd also recommend referring to your dialer's documentation send choose a format that is comfortable. Lync, for example, has thorough documentation, but acceptable characters vary slightly from 3CX or asterisk.

That said, I'm having trouble finding where it says that all phone numbers should have the + sign in front of them to be in 'international format' i.e. able to be dialled to/from anywhere.........

That would seem to confirm to me that all numbers entered in the AD User object in an international company must compy with these ITU standards to be diallable.

Does anyone else have any comments ?
