Dear ,
we have lync 2013 in our setup with polycom CX500/600/700/3000 devices.
on phone when we check contact card of any user , by default SIP address display , telephone or mobile numbers not display.
but when we add contact on outlook , telephone & mobile numbers also displayed on phone.
if we make a call by numbers , some time work number Is displaying.
is this default behavior or work around.
