Hello thank you for enrolling in the school's Burla freeware business phone systems on Asterix Isabel

00:06.840 --> 00:09.720
My name is gnomon Han and I'm the course instructor.

00:09.720 --> 00:15.240
I have a great experience in designing the open source a pretty foolish solution for small businesses

00:15.240 --> 00:16.360
to the enterprise level.

00:16.380 --> 00:21.610
Working with IP telephony is a fun Soulard began before a deep dive into the course.

00:21.610 --> 00:23.130
Let's start from scratch.

00:23.160 --> 00:24.300
So what is Isabel.

00:24.300 --> 00:30.540
Isabel is the open source platform for Unified Communications combined in a single server package.

00:30.540 --> 00:37.680
Open source means it is a reliable source code and no licensing costs as it's under Ganu GPL.

00:37.680 --> 00:43.880
GPL is a software licensing type created by a Free Software Foundation by Richard Stallman.

00:43.920 --> 00:45.780
But what is unified communication.

00:45.780 --> 00:51.810
Unified communication is the marketing buzzword describing the integration of our real time enterprise

00:51.810 --> 01:00.210
communications services such as wice instant messaging fax mobility features single number reach audio

01:00.210 --> 01:07.710
video and that single number read means you can dial using the voice and fax on a single number is a

01:07.760 --> 01:16.770
components Isabels can be used as an IP PBX IP IPB has private running Exchange as a fax server as an

01:16.860 --> 01:19.290
email instant messaging.

01:19.290 --> 01:22.910
I am calland collaboration.

01:23.010 --> 01:27.650
All these are all companies true quite a this operating system to run on.

01:27.750 --> 01:37.080
Now folder is a bit is default of open source elastics and assets acquired by a tree cx exist and no

01:37.080 --> 01:40.090
longer available as open source platform quar wife.

01:40.140 --> 01:42.040
So what is actually software for.

01:42.070 --> 01:47.600
Let's try to understand the software for the software engineering a broader fault.

01:47.610 --> 01:54.390
Happens when developers take a copy of source sourcecode from one software package and start independent

01:54.390 --> 01:59.250
development on it creating a distinct and separate piece of software.

01:59.310 --> 02:05.760
So this is the same what has been done with the elastics elastics acquired by a proprietary one system

02:05.820 --> 02:12.460
and then the theme of open source and as they created the form from the existing elastics and then they

02:12.460 --> 02:14.160
name it as is a.

02:14.280 --> 02:20.700
Open Source IP telephony platform Nigora pretty system use but as of it is based on Linux distribution

02:20.700 --> 02:21.950
costs and DOS.

02:21.960 --> 02:27.750
You can get more detail about SEND US accent or is an architecture and this area.

02:27.840 --> 02:32.220
At bottom you can see it's an operating system with a good hardware support.

02:32.220 --> 02:38.220
As I said earlier the core operating system is based on some DOS then on communication later we have

02:38.220 --> 02:42.640
a different platform tool that help us to configure the required services.

02:42.690 --> 02:49.170
As you can see the telephony component telephony it is using asdis and then on the web interface we

02:49.170 --> 02:51.140
have a bit of that framework.

02:51.150 --> 02:58.020
So basically is a bill as a web interface GUI for the open source acetates IP telephony platform focus

02:58.020 --> 03:06.510
of discourses on IP telephony IP PBX IP telephony an IP telephony component is based on your most popular

03:06.510 --> 03:08.940
open source communication platform.

03:08.940 --> 03:10.160
So whether or not this school.

03:10.180 --> 03:16.430
If you go to all these lectures and exercises you would have a complete working IP telephone system.

03:16.500 --> 03:23.070
The Course earlier was recorded with elastics IP PBX and then allow sick as I said earlier was acquired

03:23.070 --> 03:26.370
by DCX and no longer available as a free software.

03:26.380 --> 03:33.520
Isabel is the Internet solution that is based on open source and derived from elastics and regularly

03:33.520 --> 03:36.190
of course with the news of election videos.

03:36.220 --> 03:41.820
There are still some videos that are based on elastics center sonly term and logo change.

03:41.830 --> 03:43.270
The rest remains Cym.

03:43.300 --> 03:44.900
See you in the next lecture.
