概要

TLDRThe video provides an overview of SIP (Session Initiation Protocol), which is essential for initiating, controlling, and ending communication sessions over IP networks. Through a simplified example of making a phone call, the video highlights how SIP sends invitations and confirmations between devices, allowing seamless communication regardless of device type or location. SIP acts as a standardized language that enables diverse devices to connect and communicate. It is increasingly important in modern communication, particularly in hybrid work settings where traditional infrastructure is less relevant, making communication more flexible and stable.

    SIP, or Session Initiation Protocol, is a communication protocol used to establish, manage, and terminate communication sessions over an IP network. It underpins a wide variety of internet communication forms, including phone calls, video chats, and online gaming. During a SIP call, a series of signals facilitate the connection between devices; for instance, when calling a colleague, an invitation is sent via a SIP server, which requires acceptance before establishing the communication session. This protocol standardizes the interaction between diverse devices, ensuring seamless communication regardless of the technology used. SIP is crucial in supporting the shift towards hybrid working, providing reliable communication solutions without the constraints of traditional infrastructure.

    What is SIP? SIP stands for session protocol which by literary definition it's a protocol
  • 00:00:07
    that starts a session and if we Google what is a session we will find out that it refers
  • 00:00:12
    to a communication session realized by exchanging media through an IP network it's like text
  • 00:00:18
    to messages audio and videos nowadays most of our communication on the internet from
  • 00:00:24
    making phone calls to video chat and conferences and even chatting in online games they're
  • 00:00:31
    all based on SIP so how does SIP work how does it make the exchange of media happen
  • 00:00:38
    in this video we will give you a quick explanation and try to make it as easy as possible alright
  • 00:00:45
    here we go for starters we'll explain how does it initiate a communication let's take
  • 00:00:51
    a SIP phone call as an example if you need to call a colleague you dial the number and
  • 00:00:57
    your colleague's phone rings you wait for a while then your colleague answers the call
  • 00:01:03
    and you can talk that's everything you can experience and may think this is the way it
  • 00:01:08
    works however before you guys can really start a conversation your phone must firstly let
  • 00:01:15
    you talk to your colleague's phone to establish a communication session using a series of
  • 00:01:19
    signals let's just break it down so right after you dial the number your phone actually
  • 00:01:25
    sends an invitation through the SIP server to your colleagues fell that basically says
  • 00:01:31
    hey my guy wants to talk to your guy is it ok
  • 00:01:36
    your colleague's phone will see the invitation and if everything's okay approve the request
  • 00:01:41
    by sending back a message that says sure I agree and now I am ringing
  • 00:01:45
    my guy should be here to answer in no time then if your colleague hears the phone ring
  • 00:01:51
    and answers it your colleague's phone will send a notification hey my guy picked it up
  • 00:01:57
    they can speak
  • 00:01:58
    then you confirm your phone will then respond ok confirmed let them speak
  • 00:02:05
    this way the call is established and you can start to talk starting from now your conversation
  • 00:02:11
    will be flowing between you and your colleague on the network as multimedia stream when you
  • 00:02:16
    finish and hang up the call your phone will immediately send out a signal that says okay
  • 00:02:22
    we're done good job see you next time and your colleagues phone will respond with another
  • 00:02:28
    message you too see ya
  • 00:02:33
    now the call is over this session is officially ended this is how SIP initiate, control, and
  • 00:02:40
    ends a session it's realized by communication between participated devices now let's get
  • 00:02:46
    into the protocol part what is the protocol and why do we need it to initiate the session
  • 00:02:53
    in many cases within a session the participants are likely located in very different places
  • 00:02:59
    using various types of devices like computers smartphones tablets IP phones and IP cameras
  • 00:03:08
    their internet environment operating process and structure are likely to be very different
  • 00:03:14
    so for them to interact like we show in our previous example we need to guarantee that
  • 00:03:20
    all the devices are using the same language and this language it's SIP we can think of
  • 00:03:27
    SIP as a language for the devices to communicate with each other just like human language SIP
  • 00:03:34
    it's a request to response sequence every sentence and every word of it is standardized
  • 00:03:40
    and globally acknowledged that's why we call this a protocol it's a root of procedure which
  • 00:03:46
    is agreed upon by everybody so this is SIP a standardized derivative procedure for devices
  • 00:03:52
    to initiate control and end a session on an IP network it's responsible for most of our
  • 00:03:59
    daily communication sessions and multimedia transport online not only audio calls but
  • 00:04:05
    also text videos interactive games and even virtual reality sessions SIP is there to us
  • 00:04:13
    get connected no matter where we are and what devices we're using as long as there are Interenet
  • 00:04:20
    of course this is a quick explanation of the concept there are way more details when it
  • 00:04:26
    comes to sip but from a usage perspective it has been applied in so many areas especially
  • 00:04:33
    now when companies start to embrace the idea of hybrid working sip makes internal and external
  • 00:04:39
    communication smooth and stable in hybrid work scenario we're no longer tied down by
  • 00:04:45
    the physical lines and infrastructures if you want to explore further on how sip has
