I'm having a real headache trying to get the lync clients (especially lync phone edition clients) to show extension numbers while dialling.
We have our uri's set in the format tel:+441623726487;ext=201 and the same for the users in AD. All of the contact cards now populate with +441623726487 and when you dial an extension into a phone or client it resolves it to +441623726487. Although if you press call it does call the extension, this is going to be very confusing to users. It also showed on the Phone Edition home screens with +441623726487;ext=201.
The dial plan for internal extensions is set to:
^([2-3]\d{2}|400)$
+441623726487;ext=$1
I have played around with the Company_Phone_Number_Normalization_Rules.txt and have added:
(\d{3})
+441623726487;ext=$1
This made no difference, so also added:
\+44(\d{4})(\d{6});ext=(\d{3})
$3
This converted the home screen number from +441623726487;ext=201 to 201 which looks much better for the user. But nothing seems to work with the contact card or extension resolution. Made more difficult from the fact that the extension isn't shown in the contact card so I wouldn't be able to normalise it anyway.
I thought about using the uri's TEL:201 as the extensions are internal only and not DID, would this cause other problems though?
Please help!
