I do phone sessions with my t ever since she moved, over 2.5 years ago now. It would be a huge deal for me if someone else answered her phone at our scheduled time - in fact I think I would immediately freak out and assume that something had happened to her. And I think that I would have EVERY right to ask who that was - because like SD said I expect the situation between t and me to be private, so why would someone else be there answering the phone, is that person listening to her side of our call? Oh that would bother me to no end and I would say so to t.
