If I have contact with my therapist outside of session, it is via phonecall.

I only contact him when I am in a state a crisis that I am unable to manage using the skills at my disposal, or if their is a major emergency in my life, so the contact is not frequent. If I really need that much contact, I schedule and extra appointment.

My therapist has no boundaries about contacting him in those instances. I am not one to abuse the privilege on contacting between sessions, so he has had no need to place any particular rules on me about contact. My pdoc has said the same thing. He knows if I call him, it is an emergency.
