To communicate with (someone) by telephone
The phone woke me up, even though it wasn't very loud.
Is he listening to your phone call?
Martha handed her the phone and I could tell by the look that quickly appeared on her face, it was not good news.
The phone was in the kitchen and we gave Howie privacy.
The longer Howie spoke on the phone, the more I felt guilty that we were manipulating him into a parlor game at the expense of his privacy.
