Therapy carried out over a phone is known as telephone based therapy. The major advantage of this therapy is its convenience. When it is physically not possible to go out and meet your therapist, it seems feasible to do so over the phone. However it also has downsides, the biggest one is not being able to see each other, which is a hindering factor for building a positive therapeutic relationship. It is difficult for the therapist to judge the client’s emotions as s/he cannot read their facial expressions or body language.
