The book presents all the theoretical foundations to analyze the new technology that is intended to be implemented in Ecuador because as we all know the use of voice calls through the use of packet data in communication networks, takes a very important role in this era as it is a feasible means for communication, it should be noted that the quality of voice through the use of packet data currently has many defects and that is why it is intended to introduce voice over LTE with the use of new generation networks. Volte is an evolving technology of voice service and my contribution is to determine the benefits it has and the advantages it offers when introduced as a new technology for the improvement and optimization of voice calls using packet data.
