Understanding SIP

SIP stands for Session Initiation Protocol. With SIP, Voice over Internet Protocol is possible. You can run your voice calls, video calls, and instant messaging through an internet-based VoIP phone service provider. SIP calling will transform the quality of your business phone system while bringing its cost down. In order to control the SIP based call, communication is sent over the control channel and the most popular number for this is Port 5060.
