Before you start building up our IP telephony system or phone system which is based on the IP Let try

1
00:09.210 --> 00:14.160
to understand some terms and protocol related to the IP telephony

2
00:18.150 --> 00:26.070
IP protocol works at a network level where information is sent in packets called IP packets.

3
00:26.070 --> 00:33.090
Now this is something more technical definition of IP protocol and off course this is a technical course. 

4
00:33.480 --> 00:41.800
but let understand from a very layman definition. The network that we connect our computer devices like laptop

5
00:41.830 --> 00:50.780
etc. is an example of this network once connected to the IP network we are able.

6
00:50.890 --> 01:01.190
to surf the internet can send an email or even can do the chat each of this service is using a particular

7
01:01.310 --> 01:02.640
IP protocol.

8
01:02.840 --> 01:13.950
For example when you surf a web page you type http://website-address.com in your

9
01:13.990 --> 01:25.650
browsers know as to keep the protocol and distance namely the question of the age of X-server and then

10
01:25.650 --> 01:35.310
transport on this protocol and Appia and over that browser and Keshav why scal the same happen.

11
01:35.380 --> 01:49.290
Thats why we call it ype or Weissmuller Internet protocol as SATB is a protocol that is the ideas from

12
01:49.380 --> 01:52.240
Betson were lower left browser.

13
01:52.830 --> 02:03.030
Similarly we need a protocol that can daddy or twice from our endpoint device like IP phone with a Weismann

14
02:03.040 --> 02:04.190
one.

15
02:04.350 --> 02:07.380
And then why so Fondren it to all or die.

16
02:07.440 --> 02:15.250
Destination this protocol is known as sixty's DeWyze in Oakland.

17
02:15.330 --> 02:18.020
Colonel Paul funda woi.

18
02:18.490 --> 02:22.870
Yes Internet Engineering taskforce standard for what communication.

19
02:23.180 --> 02:27.390
This means N.Y.P.D. Weismann affected by Venda.

20
02:27.600 --> 02:36.440
It has to be compatible with sic for standard voice communication little more anything about sick sin

21
02:36.530 --> 02:44.460
is mainly responsible for signaling and establishing session if uses default or 5 0 6 0.

22
02:44.620 --> 02:52.130
Once this session is establish the wife's contents flow using the protocol known as RTP.

23
02:52.200 --> 03:02.400
Meantime perhaps all that that uses or ranging from 10000 to 20000 along with RTP.

24
03:02.420 --> 03:11.660
There is another protocol called as DP which is known as session disruption protocol the SDP contain

25
03:11.750 --> 03:22.030
information about stablish session night which voice Kordek is being used now at this stage.

26
03:22.030 --> 03:28.420
If you don't understand or you are not able to grab these information don't worry about it.

27
03:29.450 --> 03:33.930
As you progress with the course you will get used to it.

28
03:33.950 --> 03:35.900
It isn't that difficult.

29
03:35.900 --> 03:36.500
Trust me.
