I have called my T a couple of times between scheduled sessions, but it's only been to schedule an extra session. He doesn't really work with me on the phone. He's never given me an email address, so I assume that isn't part of his usual practice. His voicemail message has an emergency number for current clients to call if there's a crisis, but I've never done that.

He completely threw me one time by answering the phone directly - I was totally expecting his machine and had the message I was going to leave all ready in my head. When he answered, I just kind of stammered for a minute.
