説明
SIP (Session Initiation Protocol) is a protocol used in VoIP communications allowing users to make voice and video calls, mostly for free. We’ll keep the definition in this article to something simple and practical. If you want a more technical insight of SIP, read its profile.
Why Use SIP?
SIP allows people around the world to communicate using their computers and mobile devices over the internet. It is an important part of Internet Telephony and allows you to harness the benefits of VoIP (voice over IP) and have a rich communication experience. But the most interesting benefit we derive from SIP is the cutting down of communication costs. Calls (voice or video) between SIP users are free, worldwide. There are no boundaries and no restrictive laws or charges. Even the SIP apps and SIP addresses are obtained free.
SIP as a protocol is also very powerful and efficient in many ways. Many organizations use SIP for their internal and external communication, centered around a PBX.
