Objective: We required asterisk VOIP calling project with Asterisk GUI.With this configuration we will call to any number with PIN

dialing.

After dialing PIN number user will connect to another extention & starts calling.

Requirements:

1.Asterisk 1.6.2.20

2.OS: Debian 2.6.26-x-64

3.Asterisk GUI

4.Call forwarding: Through voipporovider.

5.Installed Zaptel,libpri & X-lite 4 for calling.

Steps:

1.First we installed Debian-2.6.26 as OS.

2.We installaed asterisk 1.6.2.20

3.Installed Asterisk GUI (For look & feel interface for adding extentions & trunks etc)

4.Added DID of voip provider for direct inward dialing from customer side.

5.Installed X-lite 4

Now customization & configuration steps start:

Configuration:

1.We added extentions in asterisk server.

2.After that added sip trunks.

3.Set IVR play when customer calles to DID.

4.IVR will ask for dialing desired extention number.We configured here, users contact number(landline/cell number).

5.Configured X-lite to connect with our server.

6.Set DTMF code,proxy settings,domain,network etc.

After dialing DID an IVR will play & ask for desired extention number.After dialing desired extention you can call to desired number,

that mapped with extention.

I just want to know the better & easiest GUI for the configuration of Asterisk VOIP calling.

Getting the ISO images

I’m not going to tell you how to create the CD’s required to install Linux, there are other sites for this. You can find the ISO images required from places like http://www.linuxiso.org. Download the ISO images and burn them. For This installation you only actually need disks 1, 2 and 3 (the assumption is you are using the default language settings)– If you are pushed for a network connection you can get away with only downloading and burning those, however, I would recommend getting the whole set for the sake of completeness.

Installing Linux

The first step is to insert CD 1 of your freshly burned ISO images into the target machine’s CDROM drive and boot. At this stage I’m going to make an assumption that you are either installing Asterisk on a new machine or overwriting the disks of whatever was there before. If you want to dual boot into Asterisk, please look elsewhere for initial configurations. You might want to consult your physician too. I make no apologies that this section is going to treat you like a moron; this is intentional. Since we want to be sure that you have no problems running Asterisk we need to make sure that your installation matches the one I used to build and run it.

The first thing you will need to do on your target machine is ensure that you can boot directly from CD. Most modern (if not all) will allow this, it is usually just a setting in your BIOS. If you don’t feel comfortable with messing in the BIOS the simplest test you can do to check and see if booting from CD is enabled is, funnily enough, to put CD 1 into the drive and reboot the machine. If the machine starts to boot and eventually shows a screen like the one on the following page, then you are ok. If you are happy fiddling with the BIOS then just enable booting from CD and make it the first device to attempt to boot from.

In either case you should have something like this appear on your screen:

At this point all you need to do is press ENTER. After a short while, you will be presented with the following introductory screen:

Click the NEXT button

Select the language you want to use during the installation. Since I used the default on English, all the following screens will also be in English. Then Click NEXT.

Select the keyboard layout for your particular PC. Most keyboards in the English speaking world tend to be U.S. English but check yours.

Since we are not going to be installing a windowing system on this machine, in all honesty we don’t care about the mouse. Click NEXT.

Since we are going to build a custom installation select CUSTOM and click NEXT.

This bit might seem a little scary, there’s nothing to worry about, since we have already established that we are NOT going to dual boot and there is nothing that we want to keep on the disks in this machine. You did check that right?! Click NEXT.

If you get the previous screen, don’t worry too much just click YES. You many note that the message box refers to ‘hda’ not ‘sda’, don’t worry about this either, it’s just the type of disks you are using. If you have IDE disks then this would say ‘hda’.

Depending on the state of this machine and the disks before you started this install you can either select ‘Remove all Linux Partitions on this System’ or ‘Remove all Partitions on this system’

If the disks have been previously used for another Operating system then select the ‘Remove all partitions on this system’ option. If your disks are brand new and have not been used before then either of the first two options is fine.

The box below these options will list the hard drives available on your system, leave the selections alone.

Click the NEXT button. If you chose to remove all partitions on the system you will see the message box on the following page. Again the disk name /dev/sda may and most likely would be /dev/hda…

Click YES…

You should see the following screen showing how the disks will be laid out, click the NEXT button.

Click NEXT


Now comes the hard part. If you know nothing about your network then we are going to be a little stuck. This is the part that is specific to your installation. I am not going to attempt to explain how networks function, if you have one they you should at least understand the terms in the next couple of paragraphs.

As shown on the screenshot on the previous page, the default for a Red Hat installation is to use DHCP. If you are using a DHCP server on your network then you can click NEXT. If you are not then you will need to click the ‘edit’ button, then deselect DHCP and enter an IP address and subnet mask for this machine. As a side note most home run networks tend to use the address range 192.168.0.x and a subnet mask of 255.255.255.0 – The x being replaced with the individual IP address of a particular machine. You can establish this by looking at one of your other machine’s, and its configuration settings. Again, generally, the Gateway and DNS are usually going to be something like 192.168.0.1 for both. This is however VERY SPECIFIC to your network. You much make the setting match your existing network.

If you are using DHCP then for the hostname you can let DHCP handle it. If not then select ‘manually’ and type a name for this host.

Again, for a non-DHCP environment fill in the Gateway and Primary DNS fields. Do NOT use the settings in the above screenshot unless they match your network. Once you have done this click NEXT

Select ‘no firewall’ and click NEXT.

Click NEXT. If you want to use additional languages, select the ones you want first.

Select your location or at least the nearest place to you that is listed and click NEXT.

Enter a password for the ‘root’ user. If you were unaware, the root user is like the administrator account on a Windows machine, the big boss account.. Use TAB or the mouse to move between the fields. Once you’ve done that (and remembered the password!) click NEXT.

Click NEXT

Now we have to select the applications that we want to install. The only things you need to select are:

· Development Tools

· Kernel Development

· Text Based Internet (optional but advised)

Make sure you also have ‘Select individual packages’ selected (see cursor on previous page screenshot).

Now click NEXT

Select ‘Flat View’ and ensure that the following ADDITIONAL items are selected:

* OpenSSL-Devel
* Readline41
* Ncurses4
* Ncurses C++ Devel
* SOX

Now click NEXT

Ok, this is it, we are about to do the install, Click NEXT

The first ting you’ll see is the disks being formatted and partitioned, once complete the various packages will be installed. You will be prompted to insert disks, change the CD, and then click OK.

You don’t really need to create a boot disk. Select no and click NEXT.

Do NOT remove the CD, the install will eject it for you, Click EXIT and your machine will reboot. Once complete you will be presented with something like:

You may now dance around the room a little; you have completed the Linux install part of Asterisk…

Get a coffee, tea, cola or drink of your choice and bask in this glorious moment. Then read the next section on installing Asterisk.

Asterisk is released as open source under the GNU General Public License (GPL), and it is available for download free of charge. Asterisk® is the leading open source telephony project and the Asterisk community has been ranked as a key factor in the growth of VoIP.

What Does Asterisk Do?

Asterisk is like an erector set or a box of Legos for people who want to create communications applications. That’s why we refer to it as a “tool-kit” or “development platform”. Asterisk includes all the building blocks needed to create a PBX system, an IVR system or virtually any other kind of communications solution. The “blocks” in the kit include:

* Drivers for various VoIP protocols.
* Drivers for PSTN interface cards and devices.
* Routing and call handling for incoming calls.
* Outbound call generation and routing.
* Media management functions (record, play, generate tone, etc.).
* Call detail recording for accounting and billing.
* Transcoding (conversion from one media format to another).
* Protocol conversion (conversion from one protocol to another).
* Database integration for accessing information on relational databases.
* Web services integration for accessing data using standard internet protocols.
* LDAP integration for accessing corporate directory systems.
* Single and mult-party call bridging.
* Call recording and monitoring functions.
* Integrated “Dialplan” scripting language for call processing.
* External call management in any programming or scripting language through Asterisk Gateway Interface (AGI)
* Event notification and CTI integration via the Asterisk Manager Interface (AMI).
* Speech synthesis (aka “text-to-speech”) in various languages and dialects using third party engines.
* Speech recognition in various languages using third party recognition engines.

This combination of components allows an integrator or developer to quickly create voice-enabled applications. The open nature of Asterisk means that there is no fixed limit on what it can be made to do. Asterisk integrators have built everything from very small IP PBX systems to massive carrier media servers.

Asterisk In Action: Key Applications

Asterisk As A PBX

Asterisk can be configured as the core of an IP or hybrid PBX, switching calls, managing routes, enabling features, and connecting callers with the outside world over IP, analog (POTS), and digital (T1/E1) connections.

Asterisk runs on a wide variety of operating systems including Linux, Mac OS X, OpenBSD, FreeBSD and Sun Solaris and provides all of the features you would expect from a PBX including many advanced features that are often associated with high end (and high cost) proprietary PBXs. Asterisk’s architecture is designed for maximum flexibility and supports Voice over IP in many protocols, and can interoperate with almost all standards-based telephony equipment using relatively inexpensive hardware.
Asterisk As A Gateway

It can also be built out as the heart of a media gateway, bridging the legacy PSTN to the expanding world of IP telephony. Asterisk’s modular architecture allows it to convert between a wide range of communications protocols and media codecs. Asterisk as a feature/media server.

Need an IVR? Asterisk’s got you covered. How about a conference bridge? Yep. It’s in there. What about an automated attendant? Asterisk does that too. How about a replacement for your aging legacy voicemail system? Can do. Unified messaging? No problem. Need a telephony interface for your web site? Ok.

Asterisk In The Call Center

Asterisk has been adopted by call centers around the world based on its flexibility. Call center and contact center developers have built complete ACD systems based on Asterisk. Asterisk has also added new life to existing call center solutions by adding remote IP agent capabilities, advanced skills-based routing, predictive and bulk dialing, and more.
Asterisk In The Public Network

Internet Telephony Service Providers (ITSPs), competitive local exchange carriers (CLECS) and even first-tier incumbents have discovered the power of open source communications with Asterisk. Feature servers, hosted services clusters, voicemail systems, pre-paid calling solutions, all based on Asterisk have helped reduce costs and enabled flexibility.

Asterisk Everywhere

Asterisk has become the basis for thousands of communications solutions. If you need to communicate, Asterisk is your answer.

Supported platforms

Asterisk® is primarily developed on GNU/Linux for x/86 and runs on GNU/Linux for PPC along with OpenBSD, FreeBSD, and Mac OS X. Other platforms and standards-based UNIX-like operating systems should be reasonably easy to port for anyone with the time and requisite skill to do so.

Supported hardware

Asterisk® needs no additional hardware for Voice over IP. For interconnection with digital and analog telephony equipment, Asterisk® supports a number of hardware devices, most notably all of the hardware manufactured by Digium®, the creator of Asterisk®.

Features

Asterisk-based telephony solutions offer a rich and flexible feature set. Asterisk® offers both classical PBX functionality and advanced features which interoperates with traditional standards-based telephony systems and Voice over IP systems.

Supported protocols

Asterisk® supports a wide range of protocols for the handling and transmission of voice over traditional telephony interfaces including H.323, Session Initiation Protocol (SIP), Media Gateway Control Protocol (MGCP), and Skinny Client Control Protocol (SCCP).

Using the Inter-Asterisk eXchange (IAX™) Voice over IP protocol Asterisk® merges voice and data traffic seamlessly across disparate networks. The use of Packet Voice allows Asterisk® to send data such as URL information and images in-line with voice traffic, allowing advanced integration of information.

Asterisk® provides a central switching core, with four APIs for modular loading of telephony applications, hardware interfaces, file format handling, and codecs. It allows for transparent switching between all supported interfaces, allowing it to tie together a diverse mixture of telephony systems into a single switching network.
