The integration of this technology within companies has increased efficiency internally and in the relationship with the customer. Becoming indispensable over time, the use of a unified communication network within companies has many advantages, including:
Numerous tools such as answering machines, call transfer as well as conferencing, or shortened internal numbers, all directly impact productivity.
The ability to link all computer devices
under the same network, increases
the flexibility of the company.

Two categories of Voice on IP can be proposed, one called Virtual PBX, and the other Trunk SIP.
