The technology of sending voice is already over a hundred years old, but earlier there had been less important developments in technology over the earlier systems of PBX and key system technologies which had been developed for many years. The new technology that has now been developed is of sending voice over IP which is replacing the earlier TDM products and now with the development of technology the changes in technology of voice can have an important role to play in organizations.

At the same time, this cannot be removed totally since it has to handle the call overflows and any calls which are not targeted for the remote site. There are models available which will enable the calculation and justification for these network integration projects.
