I have had a few regular scheduled phone sessions when either my T or I were out of town. I don't like them as much as in-person sessions, but I like them better than nothing. My T is good with body language and facial expressions and sensing subtle changes in the energy in the room, and she can't do that very well over the phone, which detracts a bit from the experience for me. I have had a couple of times when I decided to use that extra emotional distance during a phone session to tell her a few things that I wasn't quite ready to say to her face, either because I felt embarrassed or I didn't know if she would think the things were important. I thought that approach was a productive use of a phone session. I didn't find the pauses awkward, but I have been pulled out of the moment once or twice by wondering if the call had been dropped. So go for it if you want to do it, but maybe try to think ahead of time about what might make the session feel useful to you.
