These are all standard protocols implemented to enhance the VoIP network for better integration of various demanding business applications and services to the IP Network. These are the services or applications that you’ve been using all along, and probably didn’t know it. With the implementation of these protocols, we can enjoy such services as videoconferencing, NetMeeting, and various Messenger Services which support both voice and video calls across the networks.We are able to make a call or video call from our computer to another computer, whether it is connected locally at home, at our office, or across the globe to another country.
