Good morning Everyone!
I am a network administrator who is being pushed more and more towards telephony due to company shifts. That being said I am booked for training in Avaya Aura CM 8 administration but I would like to acquire a book that teaches all the fundamentals of telephony with some background. Any recommendations are welcome!
