Configuring Sip to Skype gateway - 3CX Gateway for Skype [Part 1]

Pre-requisites:

The following pre-requisites are needed for the 3CX gateway for Skype to operate:

1. Skype version 4.1.0.179 or above is required.

2. The Skype Client must be installed on the same machine as 3CX Gateway for Skype. Skype can be downloaded from here: http://www.skype.com/intl/en/download/skype/windows/

3. 3CX Gateway for Skype must be installed on the same machine as 3CX Phone System. You can download 3CX Gateway for Skype from here: http://www.3cx.com/downloads/3CXGatewayforSkype2.msi

4. Audio drivers must be installed and configured correctly – this is a Skype pre-requisite.

5. 3CX Phone System Version 7.1.7137 or higher is required

6. The 3CX Gateway for Skype was tested on the following operating systems Windows XP, Vista 32/64 bit, server 2003 32/64bit, Windows Server 2008 and Windows 7.

7. Known issues in the Skype client:
a. Display status on ringing will show green on multiple incoming calls
b. The Skype client does not appear to be 100% stable on Windows 2008 which obviously effects 3CX Gateway for Skype

8. 3CX Gateway for Skype can not be installed on a domain controller

Part 1: 3CX Management Console Gateway creation

Step 1: Add a Skype PSTN gateway from the 3CX Management Console

Create a PSTN gateway from the 3CX Management Console. Click on Add Pstn Gateways, select the 3CX Gateway for Skype template and specify a name for this gateway.

Step 2: Configure IP, and Port for 3CX to communicate to the 3CX Skype Gateway

Specify the Gateway, Hostname and IP of the machine where 3CX Gateway for Skype will be installed. Because the 3CX gateway for Skype will be installed on the same machine, specify 127.0.0.1 (localhost) and port is 6060.

Important : When creating additional 3CX Gateway for Skype ports you must increment the port by 2. For example: the second gateway must have 6062 set.

Step 3: Creating the port for the 3CX Gateway for Skype

Take note of the details presented in this page and click Next to proceed. These details will be needed when creating a Skype Channel in 3CX gateway for Skype to enable it to register to 3CX Phone System.

Step 4: Outbound rule creation

Create an outbound rule for this Skype Gateway with a prefix.

Part 2: 3CX Gateway for Skype Configuration instructions

Now download 3CX Gateway for Skype package from the following link. After the installation steps have been completed, clicking Finish on the last screen will open the initial window that will enable you to start the configuration for the Skype Gateway.

Step 1: Creating of windows user accounts.

Each Skype gateway created in the Management console needs a corresponding Skype channel. Each channel created in turn needs to have
• Skype ID
• A newly created Windows User account associated with it. This Windows User account cannot be an already existing account - it will be created by 3CX Gateway for Skype.

Now Click Create. Enter the 3CX Hostname or IP. In this case the 3CX GFS will be installed on the same machine so you can enter localhost or 127.0.0.1

All Channels created will need a separate Windows User Account to operate under. In the computer account settings section you can configure a prefix for computer accounts that will be created every time you create a new Skype™ port. If, for instance, the prefix is 3cxskypeacc, accounts will be created as 3cxskypeacc01, 3cxskypeacc02 and so on.

Step 2: Creating of Channels to communicate with the gateway ports. [Contd..]

How To - Install JunOS on Vmware [Updated]

Olive is a machine that run JunOS not in Juniper machine. Not like Cisco IOS that have Dynamips as ready to use IOS simulator, there is no ready to use JunOS simulator. Fortunately, JunOS runs on top of FreeBSD machine, so that we can simulate by install it on FreeBSD machine. So, to whom that want to learn JunOS, or want to take JNCIE :), but do not have Juniper machine, Olive is the solutions. This procedure will explain how to install JunOS in VMWare or Olive.
Here are you need to prepare, FreeBSD image, VMWare, and Junos image itself. Follow steps below for installing Olive. 



1. Installing FreeBSD Using VMWare
Download FreeBSD here. Download JunOS image, just googling to find it.
Install FreeBSD in VMWare. I create 3 Gb as virtual disk. Later, we will upgrade to Junos 9.x that need 3 Gb minimum virtual harddisk.
Choose Skip Kernel Configuration
Choose Express

Choose A (Use Entire Disk). Choose Q (Quit).

Choose Standard

Choose C (create).

Fill 500M, FS (FIle System), fill / on partition.

Choose C.
Fill 500M, Swap.

Choose C, Fill 100M, fill /config on partition.

Choose C, use all rest of space, fill /var/tmp on partition.

Click Q (Finish).

Choose CD/DVD. Choose Yes on answer.

Choose yes again.

Choose Root password. Fill with your root password.

Choose networking, Choose Em0.

Choose Interfaces. Choose em0.


Choose no for IPv6

Choose No for DHCP if ypu plan to configure static IP.

Fill your network configuration.

Choose Yes.

Choose Exit.

Choose Exit Install. 2. Installing Junos image

a. Copy JunOS image to FreeBSD virtual machine. Setup your FTP server, then use FTP to copy Junos image from your FTP server to your virtual machine. One recomended free FTP Server is Cesar FTP Server. It is easy to use. Although it has not been developed again, but it still can be downloaded. After setup your account and directory, do ftp from your virtual machine. Set your virtual machine directory to /var/tmp.

b. Installing JunOS image. Login to your FreeBSD virtual machine. Go to /var/tmp directory.

Do the following:

rm /dev/wd0c
ln -s /dev/ad0c /dev/wd0c
mkdir /var/etc
touch /var/etc
touch /var/etc/master.passwd
touch /var/etc/inetd.conf
touch /var/etc/group

pkg_add /var/tmp/jinstall-7.4R1.7-export-signed.tgz

Reboot your machine to finish Junos installation. 3. Getting Access to Olive Using Virtual Serial Port.
Once you reboot your Olive after installing your Junos software, you won't get access to your Olive. To get access to your Olive, you need to use serial port and Virtual Serial Port Driver. You can get Virtual Serial Port Driver software from Eltima Software. Accessing Olive using serial port:
a. Create serial port pair using Virtual Serial Port Driver software

b. Add serial port in Olive, using serial port have been made before in Virtual Serial Port Driver.
Click Add. Choose Serial Port. Use Physical Serial Port on the host. Choose serial port have been made using Virtual Serial Port Driver.




Use your favourite software to access to Junos through serial port. 4. Upgrade to Junos 8.x
In order the ethernet card detected by Junos, you need to upgrade to Junos 8.x. Because this time ethernet can not be detected, you can not use FTP to copy Junos image. You need to create other FreeBSD virtual machine, copy Junos image to that. Add your second virtual machine as second IDE in your Olive.
Mount your second drive. For example, if you copy Junos image in first partition of your second virtual machine, the do this


mount /dev/ad1s1a /mnt

Then copy Junos image to /var/tmp/ directory. Goto to /var/tmp/, then install new Junos image

pkg_add jinstall-8.3R2.8-export-signed.tgz

Reboot to complete upgrade.

shutdown -r now

After booting process, ethernet card can be detected, and you can start playing your Junos Olive with networking function.
5. Upgrade to Junos 9.x
In order to access Olive from VMWare console, you need to upgrade to Junos 9.x. To upgrade to Junos 9.x, set SCSI to FALSE (in VMWAre configuration file), then set memory to 512M minimum value. After upgrade, you can set memory back to 256 M or even 128M.

Why did Intel buy McAfee for $7.7 billion?

Intel has just bought computer and software security company McAfee according to a release issued this morning. The all cash deal is worth $7.68 billion, or $48 per share.
McAfee is one of the largest security technology companies in the world and saw $2 billion in revenue in 2009. Cyber security, whether it be on computers or mobile devices, is a lucrative business as internet use is on the rise. And McAfee also offers smartphone security software, through the recent acquisitions of Trust Digital and TenCube. Clearly, Intel wants a piece of the pie.
According to MarketWatch, Intel will pay $48 a share in cash to buy the firm, amounting to a shade under $7.7 billion. this works out as a premium of 62% over McAfee’s closing price on Wednesday.
Question is, why?
That’s a good question. Perhaps Intel feel that there’s good money in buying into a security firm, or possibly the acquisition paves the way to embed security software directly onto processors. Or maybe Intel just had the cash to burn.
Intel is not shy of carrying out acquisitions so this move isn’t that much of a surprise. With Intel’s focus being primarily on CPUs and wireless, being able to incorporate security into these devices would give it a substantial upper hand over AMD (as if it needs one, Intel absolutely dominates AMD in all areas except graphics).
Intel’s president and CEO Paul Otellin called security the “third pillar of what people demand from all computing experiences,” behind energy-efficient performance and connectivity.
McAfee, which has enjoyed double-digit, year-over-year growth and nearly 80 percent gross margins last year, will become a wholly-owned subsidiary of Intel, reporting into Intel’s Software and Services Group. The group is managed by Renée James, Intel senior vice president, and general manager of the group.

Cisco Making A Run For Skype

Cisco has made an offer to acquire Skype before they complete their IPO process, says one of our more reliable sources. We have not been able to confirm this rumor one way or another via other sources, which isn’t surprising. A company in lock down during the IPO process is usually even more tight lipped than normal.

But if true this would be one very big acquisition. Skype insiders are hoping for an out of the gate valuation of $5 billion or so, we’ve heard. Presumably Cisco would have to bidding in that range to make it interesting.

Google was also rumored to be sniffing around Skype, but antitrust concerns may have persuaded them not to make an actual offer.

How To - Install Mac OS X Leopard OSx86 on PC Dual Boot Windows 7, Vista in 9 Easy Steps

Steps to install

Before you Begin

This currently works on INTEL system with SSE3 support ONLY. An AMD/SSE2 patch should come shortly. Use CPU-Z to check the system capability if you are not sure.

Warning: the patch is rather experimental atm, and even your processor supports SSE3, the installation might still fails due to various compatible issues. Also, the patched DVD seems to be problematic, missing the booting setup part, and most likely would render a system unbootable. Most guides online are based on the instruction comes with the patch file, they didn’t actually install it! I did manage to install the Leopard on my own PC and this guide is based on my very own, first-hand experience. I’ll try to make it as accurate and correct as possible. [src : DigitMemo ]

Update: AMD/Intel SSE2 users try this. Need to patch the original Leopard DMG though, no pre-patched disk available atm.

Most Important thing you should check for is your Hardware compatibility List (HCL).

1. Download OSx86 10.5.x

Go to your favorite torrent site and Download 10.5.x of your favorite flavor among the listed ones. Latest version is 10.5.7. Though 10.5.6 is also a fair deal. Burn the downloaded “.ISO” file to DVD using PowerISO / MagicISO or any other burning software.

2. Create Partition, preparing Disk:

In windows 7 or vista, Right click My computer > Manage, click Disk Management. Here create a primary partition with minimum 8GB space, though recommended is 15GB. There is no need to format this partition. After Partition is created, right click > Mark Partition as Active.

Burn the OSX86 ISO that you downloaded from torrents on to a DVD and reboot with Boot from DVD. Now you should see Darwin load screen.

3. Booting and starting Installation

As countdown from 10 starts, press F8 key and you will be able to have some more option’s. Now type -v and press enter now entered in VERBOSE mode, this will enable you to see any errors if they occur. In case your screen freezes for more than 10 minutes than note last lines and google them to find out a solution for your problem. If every thing goes fine after 15-30 minutes installation screen appear’s hold your breath we are not quit yet here.

Alternatively, to skip the booting errors, you can try these parameters on Boot: prompt

-cpus=1, -cpus=2.

4. Configuring Installation

After boot, you enter the Graphical interface and you should be able to see a top menu. From the menu Click Utilities > Disk Utility.

Here, select the destination drive where you want to install Mac OSX. this will be the same partition we created earlier in step 1.

Now click on ERASE on right hand side and under the format option select “MAC OSX Journaled Extended” and click Erase. The disk will be erased and mounted. Close the disk utility and agree to the terms and conditions, then select the partition which you erased recently.

5. Customize the Install

The most important part is this step. Now, choose wisely what all components you need to support your running hardware. Browse at http://wiki.osx86project.org/wiki/index.php/Main_Page Navigate to the HARDWARE section and choose your version(10.5.x) and computer type (Portable/Desktop). This page should give sample hardware examples that people have tested, and modules they have selected.

If you have doubts, you can check the Insanelymac.com forums.

For most of the INTEL based systems Vanilla Kernel works very smoothly & for AMD system try Voodoo kernel. It is recommended to remove all the extra unnecessary languages as they take up about 2 gigs. Also, dont add extra Drivers (.KEXTS) which might cause conflicts. e.g. if You have NVIDIA geforce on your laptop, you should select NVDarwin from the “Graphics” section, not all.

Hit Ok when you are convinced!

6. Checking the disk and Installation of System files

Now your disk(DVD) will be checked for consistency, then, installation begins. It will take 20-45 minutes as per your hardware juice. After the installation is over, it will ask for a reboot. Remove the DVD after it has rebooted.

You should be able to automatically boot into OS X at this time.

7. Setting up the Boot Loader

Now that OS X is all working, we have to make the previous installation of Windows 7 or Vista to work. for this, I`ll use the Windows boot loader rather than chameleon boot loader built-in to OS X. This helps you prevent re-fixing MAC OS installation when you re-install windows at some time in future.

Put in your windows 7 or Vista disk, and boot from it. When installation starts, it prompts for “Recovery”. Select the recovery option. On you will be prompted to choose tools available for recovery. Select “command-line”.

DISKPART> list disk // displays the available HDD
DISKPART> select disk n // select the disk which has windows installation
DISKPART> list partition // list partitions on the selected disk
DISKPART> select partition n // select the partition number where windows was previously installed.
DISKPART> active //sets partition active
DISKPART> exit

REBOOT.

Now your vista /windows 7 should boot, If it doesn’t try this:

Boot with installation disk into windows setup, choose recovery again, and select automated recovery of boot area. Windows should fix the boot automatically, then click Fix and reboot button.

8. Adding MAC to the Boot menu via Windows:

Boot into windows normally and download EasyBCD from google. Open it, click “Add/Remove entries” navigate to “Mac”. Select Type in the dropdown to “Generic x86 Pc” and give some name in the text box below. This name will appear in your boot screen. Click “SAVE” when done and REBOOT.

9. There is no Step 9. You should be able to boot into booth MAC OSX Leopard and Windows without any issues.

Enjoy the wonderful world of MAC!

Note: If you need any assistance or have any doubt, you can get in touch with me @ahsantasneem on Twitter. Don’t hesitate.
