My first therapist answered an about 2-minute phone call during our very first meeting while I was sitting across from him. When he asked me towards the end of the session if there was anything that would discourage me from coming back, I told him straight if he had a habit of answering phone calls. Then I was only halfway out the door and he answered another call on his cell. Thinking back now, that was really weird and could have been more alarming given all the issues I ran into with him later. He did respond to the phone once or twice later as well.

Current T has his phones on "do not disturb" or silent or whatever, I've never heard or seen any sign from it. There was one phone session we had when he told me straight away in the beginning that there is a personal emergency for him and it might happen that we will get interrupted, and if that was the case, we would make up for it later without charge. He only used his electronic devices a couple times to look up something I mentioned to him online. I find his dealing with it fair and respectful.
