update of conferencing numbers.
All Non-US Dial-In Numbers do not show the "+" sign.
so it may be hard to use click2dial for many users...
All numbers should be in the same format as Skype for business likes it
Also should be here. If I go to "Conference Dial-in Numbers" page by "Find Local Number" link in invite, it shown for example right Czech Number "+420 (2) 34715804". But link in invite show only "420234715804" and it cannot be dialed.
