Convert SIP trunking to E1 - ISDN PRI or R2 MFC

2011-08-01T19:54:00.001+03:00

Saudi Telecom company (STC) started to provide SIP trunking for business customers. Heard that there is no more traditional DID DOD over E1.These services allow callers to make direct inward dialing (DID) or direct outward dialing (DOD) calls without an operator's assistance by connecting company's PBX to STC's exchange.

Business customer PBX systems and call centers usually want E1 PRI. The PRI stands for Primary Rate Interface, a term that comes from a set of telecommunication standards called ISDN or Integrated Services Digital Network. What PRI adds to a standard channelized E1 line is a dedicated signaling channel that makes call setup and teardown faster, plus the ability to provide Caller ID and ANI (Automatic Number Identification.) A E1 PRI line gives you 30 channels that can each carry one telephone call plus the data or signaling channel.

Many of corporate customers running on TDM PBX having E1 PRI interface which will not support SIP trunking. STC is providing point to point Ethernet (dedicated for voice) to deliver SIP trunking service without authentication.

VOIP Gateway equipment can act an important part in above scenario. It can convert SIP trunks to Legacy E1 (ISDN PRI/R2 MFC).one equipment can carry up to 4 E1 .And this equipment is now available in Saudi market (contact me on mail@jaizal.com for details)

Visual scenario as shown below:

Kids protection software !

2009-03-10T09:48:00.009+03:00

While using a PC children are completely out of the parental control and parents can't actually find out what their children do when they're online. Fencing children from computers or allowing using them only when parents are supervising the process is not an ideal solution. Besides producing a negative impact on relations with you child, this also makes it harder for your offspring to compete with other children, as the Internet these days gives certain social and academic advantages.

However, the Internet content should be filtered, there's absolutely no doubt. Kids protection software is probably the ideal solution in terms of internet protection for kids when parents are not at home.

Here you can download one of the best Kids protection software

A handy tool to forward ports in windows PC

2008-06-14T10:32:00.002+03:00

Analog Port mapper is a free handy tool for port forwarding in windows PC's.As far as i know it is quiet easy to forward ports in linux machine, but in windows xp so difficult to forward a port unless we have enabled ICS .it is usual to think why needed a portforwarding in a particular windows xp machine.I had a situation to make me think about this feature.In one of my network scenario ,remote locations are connected via vpn clinet software .so i can access only the PC which is installed client software in the remote network.ones i needed to acces an IP camera which is connected in remote network,make me think about any ways to reach the IP camera.Bridging VPN adapter with remote network is not a proper solution because of difficulty in DHCP assignment of VPN adapter.
However this handy tool helped me to reach to the IP camera which is in remote network subnet.the tool forwading traffics comming from port 80 of VPN adapter,to the ip address of camera and make it possible to monitor the camera from head office.

The Grid: The Next-Gen Internet?

2008-04-22T13:05:00.000+03:00

AMSTERDAM, Netherlands -- The Matrix may be the future of virtual reality, but researchers say the Grid is the future of collaborative problem-solving.

More than 400 scientists gathered at the Global Grid Forum this week to discuss what may be the Internet's next evolutionary step.

Though distributed computing evokes associations with populist initiatives like SETI@home, where individuals donate their spare computing power to worthy projects, the Grid will link PCs to each other and the scientific community like never before.

The Grid will not only enable sharing of documents and MP3 files, but also connect PCs with sensors, telescopes and tidal-wave simulators.

IBM's Brian Carpenter suggested "computing will become a utility just like any other utility."

Carpenter said, "The Grid will open up ... storage and transaction power in the same way that the Web opened up content." And just as the Internet connects various public and private networks, Cisco Systems' Bob Aiken said, "you're going to have multiple grids, multiple sets of middleware that people are going to choose from to satisfy their applications."

Build a Wireless Repeater Bridge

2008-01-12T19:15:00.000+03:00

To build a network bridge is easy through a Ethernet cable.It is used to connect two LAN segment. Making it trough a wireless link is not easier like Ethernet. The two segments will be in the same subnet and look like two Ethernet switches connected by a cable to all computers on the subnet.wireless bridge will be great idea when we don't want to run an Ethernet cable between two locations.
The following guide is explains building of a wireless repeater bridge using DD-WRT firmware from my experience
the example scenario as follows :-

Materials used :-

Linksys WRT54G as primary router

Linksys WAP54G v3 as secondary access point

DD-WRT v24 Beta (08/15/07) micro Firmware to flash WAP54g

-----------------------------------------------------------------------------------
Flash your WAP54G with DD-WRT v24 Beta (08/15/07) micro firmware

On Secondary(DD-WRT) Router make Restore Factory Defaults
Connect your PC to the secondary router via wired or wireless
Open the Wireless -> Basic Settings tab
- Wireless Mode : Repeater Bridge
- Wireless Network Mode : Mixed
- Wireless Network Name(SSID) : Same as Primary Router
- Wireless Channel : Auto
- Wireless SSID Broadcast : Enable
- Network Configuration : Bridged
- Save Settings
Virtual Interfaces Section
- Add
- Wireless Network Name(SSID) : anything Different from Primary Router
- Wireless SSID Broadcast : Enable
- AP Isolation : Disable
- Network Configuration : Bridged
- Save Settings
Open the Setup -> Basic Setup tab
- Connection Type : Disabled
- IP Address : 192.168.1.2 (Assuming Primary Router IP is 192.168.1.1)
- Mask : 255.255.255.0
- Gateway: 192.168.1.1 (IP of your Primary Router)
- Assign WAN Port to Switch : Checked or Unchecked - your choice
- Save Settings
Open the Security -> Firewall tab
- Disable SP1 firewall
- Save Settings
Open the Status -> Wireless tab
- Site Survey
- Join Primary Router
- Continue
APPLY Settings

Now you can be able to connect internet through the newly configured Secondary router. Clients will receive IP Addresses from the Primary Router.(if DHCP Server Enabled)

2007-12-16T02:18:00.000+03:00

Today i have installed three Hp 4600n printer in a network,and configured it in windows vita clients.on next moment i got calls from users , they are facing problem when printing multiple pages ..prints only first page then giving message to select tray with red light..when pressing green button to continue the job, prints a error page (Unable to store job..) rather than the rest pages.
Hard to figure out the problem.Vista auto detects the driver.played in printer setting ,disabled ram disk .... but no hope.printer acting strange things ..at last i figured out that the problem is in driver. Vista auto detects only the PCL5 driver ..no way to update the driver.
so i installed printer in server as share printer ...when trying to access printer from clients , automatically installs the PCL6 driver in clients too. choosed PCL6 driver instead of PCL5... ..
now printers are working greatly...........

The Prophet of Islam , What others say about him

2007-11-17T15:03:00.000+03:00

John William Draper
A history of the Intellectual Development of Europe, Vol. 1

· "Four years after the death of Justinian, A.D. 569, was born at Mecca in Arabia, the man who of all men, has exercised the greatest influence upon the human race…Mohammad…."

Major Arthur Glyn Leonard
Islam – Her Moral and Spiritual Value, London 1927, p.20-1

· "Mohammad was no mere spiritual peddler, no vulgar time-serving vagrant, but one of the most profoundly sincere and earnest spirits of any age or epoch. A man not only great, but one of the greatest ( i.e. truest), men that humanity has ever produced. Great, not simply as a prophet but as a patriot and a statesman: a material as well as a spiritual builder who constructed a great nation, a greater empire and more even than all three, a still greater Faith, true moreover, because he was true to himself, his people and above all, to his God."

· "The theory of Islam and Sword for instance is not heard now frequently in any quarter worth the name. The principle of Islam that there is no compulsion in religion is well known. Gibbon, a historian of world repute says, "A pernicious tenet has been imputed to Mohammadans, the duty of extirpating all the religions by sword.This charge based on ignorance and bigotry, is refuted by Qur'an, by history of Musalman conquerors and by their public and legal toleration of Christian worship. The great success of Mohammad's life had been effected by sheer moral force, without a stroke of sword."

Prof. K. S. Ramakrishna Rao,
Head of the Department of Philosophy,
Government College for Women University of Mysore, Mandya-571401 (Karnataka). Mohammed The Prophet -Re-printed from "Islam and Modern age", Hyderabad, March 1978.

· "The personality of Muhammed, it is most difficult to get into the whole truth of it….There is Muhammed, the Prophet. There is Muhammed, the General; Muhammed, the King; Muhammed the Preacher; Muhammed the Philosopher; Muhammed the Statesman; Muhammed the Orator; Muhammed the Reformer; Muhammed the Protector of Slaves; Muhammed the Emancipator of Women; Muhammed the Judge; Muhammed the Saint. And in all these magnificent roles, in all these departments of human activities, he is alike, a hero."

Jules Masserman
U.S. psychoanalyst, Time Magazine, July 15, 1974

· Leaders must fulfill three functions – provide for the well-being of the led; provide a social organization in which people feel secure and provide them with a set of beliefs.

· People like Pasteur and Salk are leaders in the first sense. People like Gandhi and Confucius on one hand and Alexander, Caesar and Hitler on the other are leaders in the second and perhaps the third. Jesus and Buddha belong in the third category alone.

· Perhaps the greatest leader of all times was Mohammad who combined all three functions."

· "Some one has said that Europeans in South Africa dread the advent of Islam -- Islam that civilized Spain, Islam that took the torch light to Morocco and preached to the world the gospel of brotherhood.The Europeans of South Africa dread the Advent of Islam. They may claim equality with the white races. They may well dread it, if brotherhood is a sin. If it is equality of colored races then their dread is well founded."

Mahatma Gandhi

in Young India

· "I become more than ever convinced that it was not the sword that won a place for Islam in those days.

· It was the rigid simplicity, the utter self-effacement of the Prophet, the scrupulous regard fro pledges, his intense devotion to his friends and followers and his intrepidity, his fearlessness, his absolute trust in God and in his own mission.

· These and not the sword carried everything before them and surmounted every obstacle."

Dr. Annie Besant
The Life and Teachings of Muhammad

· "It is impossible for anyone who studies the life & character of the great Prophet of Arabia, …., to feel anything but reverence for that mighty Prophet, one of the great messengers of the Supreme. …I myself feel whenever I re-read them, a new way of admiration, a new sense of reverence for that mighty Arabian teacher."

Sir George Bernard Shaw
'The Genuine Islam,' Vol. 1, No. 8, 1936

· "I have studied him – the wonderful man – in in my opinion far from being an anti-Christ he must be called the Savior of Humanity. I believe that if a man like him were to assume the dictatorship of the modern world, he would succeed in solving the problems in a way that would bring much needed peace and happiness.

· I have prophesied about the faith of Muhammad that it would be acceptable to the Europe of tomorrow as it is beginning to be acceptable to the Europe of today."

Rev. Bosworth Smith
"Mohammed and Mohammedanism", 1874

· "By a fortune absolutely unique in history, Mohammed is a threefold founder, of a nation, of an empire and of a religion.

· He was Caesar and Pope in one, but he was Pope without the Pope's pretensions and Caesar without the legions of Caesar: without a standing army, without a bodyguard, without a palace, without a fixed revenue, if ever any man had the right to say that he ruled by right Divine, it was Mohammed, for he had all the powers without its instruments and without its supports."

Alphonse de Lamar tine
Historie de le Turquie, Paris 1854, Vol.11.Pages 276-77

· "If greatness of purpose, smallness of means and astounding results are the three criteria of human genius, who would dare to compare any great man in history with Muhammad?

· Philosopher, apostle, legislator, warrior, conqueror of ideas, restorer of rational beliefs, of a cult without images, the founder of twenty terrestrial empires and one spiritual empires, that is Muhammad. As regards all standards by which human greatness may be measured, we may well ask, is there any man greater than he?"

Dr. Sarojini Naidu
IDEALS OF ISLAM, vide Speeches & Writings, Madras, 1918

· "It was the first religion that preached and practiced democracy; for, in the mosque, when the call for prayer is sounded and worshippers are gathered together, the democracy of Islam is embodied five times a day when the peasant and king kneel side by side and proclaim: 'God Alone is Great'... I have been struck over and over again by this indivisible unity of Islam that makes man instinctively a brother."

Thomas Carlyle
On Heroes, Hero-Worship and the Heroic in History, London 1888,p.61

· "His household was the frugalest; his common diet barley-bread and water; sometimes for months there was not a fire once lighted on his hearth. They record with just pride that he would mend his own shoes, patch his own cloak. A poor, hard-toiling, ill provided man; careless of what vulgar men toil for.

· No emperor with his tiaras was obeyed as this man in a cloak of his own clouting. During his three and twenty years of rough trial, I find something of a veritable hero necessary for that of itself."

and the model is

“Intel® 82801FBM Ultra ATA Storage Controllers-2653”

After reboot the BIOS setting can be changed back to “AHCI Configuration” setting

“disabled”

How to add music to a Powepoint presentation

2007-07-21T12:23:00.000+03:00

here you will learn how to add music or song to a power point presentation and how to get it to play across multiple slides.
(also see below How to Embed mp3 Sounds )

Step 1. Choose your file which u need to add power point presentation.
MP3 format is the better file format for power point presentation . This has the smallest file size. However there is one big problem with mp3 files that you can only link but not embed mp3 files into PowerPoint.

Step 2. Insert the music in your PowerPoint presentation.

Then from the Files of Type drop down box select mp3 format.

You will then get a message about how you want the music to start

Step3 - Setting the music to play across multiple slides

A lot of people have asked if it is possible to keep the music playing across multiple slides- for example if you wanted to make a slide show of someone's life with music playing in the background - or it could be a useful feature at a trade show.

You do this using a feature called Custom Animation. Select your music file then Right click (not the usual left click) and select Custom Animation. You can do this by selecting Slide Show > Custom Animation

How you do this depends upon which version of PowerPoint you are using.

For older versions of PowerPoint

Then select Multimedia Settings afterwards and make sure that you have selected While Playing >Continue Slide show You will then need to set the Stop Playing button and enter in the Stop Playing > After number slides the number of slides that you would like the music to play for.

If you are using PowerPoint XP the procedure is slightly different

Custom Animation > Right Click on Media and select Effect Options

You will then need to set the Stop Playing button and enter in the Stop Playing > After number slides the number of slides that you would like the music to play for.

Step 4. (Almost there). How to embed music in your presentation

The last gotcha in the process is that the music may not be embedded in your PowerPoint presentation. This means that is you save your presentation onto a CD or you are to email it, then the music may not automatically go across. It all depends upon the file size of the music.

If you want the music to be embedded in the presentation you will need to follow a couple of steps.

1. Make sure your music is in WAV format (mp3 files can only be linked and not embedded)
2. Increase the value in the Link sounds with file size greater than box to a value greater than the file size of the MP3 file. For example if the file size is 4.5MB then you will need to include a value higher than 4500. A good general purpose size that should incorporate most song files is 6000 as most mp3 files are less than 6MB. Be careful as some classical music tracks could be longer than this.

The only downside is that the file size of the final file could be quite large.

There is a 50 Mb limit for embedding WAV files. For eample if you had two WAV files of 34 MB the you will be able to embed them, but it would make your file size over 68MB.

The second question that we get asked ........

How to Embed mp3 Sounds

Most places will tell you that only wav files can be embedded in powerpoint. All other sound formats are linked. Since mp3 files can be 10 x smaller it would be very useful if you could embed them. Linked files can cause problems .

You can and here's how:

The technique is to add a header to the .mp3 file that will convince PowerPoint that it is actually a wav file. Although this will change the file name to "something.wav" the file remains an mp3 file, the same size as the original and will play in PowerPoint as an mp3 file. NOTE this only seems to work with PCs not with Macs.

You will need to download a free program called CDex to add the header. You can get it here CDex. The download page is a little confusing but the file you need is the windows exe version (cdex_170b2_ enu.exe)

With CDex use "Convert > "Add a RIFF wav header to mp2/mp3" to produce a file that will be virtually identical to the mp3 file but will have the .wav suffix and can be embedded using either of the techniques in Embedding Sound Files. The headered file should be found in the same folder as the original mps file.

If you are starting with a wav file and want to coonvert it to mp3 to reduce it's size then CDex will do this too. Choose convert > WAV files to Compressed Audio. Before you do this check Options>Settings > Filename tab and make sure you know where the converted file will be saved!

Many people speak of RIFF wav files as a special type of wav file. This is not the case RIFF stands for "Resource Interchange Fle Format" and applies to all wav files . You have not converted the mp3 to a RIFF wav merely convinced PowerPoint that the mp3 IS a normal wav file. RIFF wav has however slipped into technically incorrect common usage to mean an mp3 file with a wav header.
