1 PBX in a Flash PBX in a Flash Installation Digitally signed by PBX in a Flash DN: cn=pbx in a Flash, c=us, o=pbx in a Flash, ou=development, =none Reason: I am the author of this document Date: :40:00-05'00' November 25, 2007 Welcome! This document will describe the configuration and installation PBX in a Flash. I have tested this on Lab, Production, and VMware machines with great success. Does this mean it is absolutely safe? Not in your life! No warranties express or implied at all! But I use it day to day in mission critical applications. NOTE THIS IS A WORK IN PROGRESS PLEASE LET ME KNOW IF YOU FIND ANY ERRORS. This work is copyright 2007 by Thomas A. King. This work may not be altered or modified without express written permission of the author. You may copy this manual and use it freely; however this notice must be included with the document. This manual is NOT released under the GNU General Public License. WARNINGS This script was tested and vetted on machine running INTEL processors with lots of RAM and NO, I SAY AGAIN NO SATA or RAID controllers present. All of the machines used in the development of this script use PATA drives. OVERVIEW PBX in a Flash is based on Centos 5, Asterisk 1.4, FreePBX 2.3. LAMP, etc, all rolled into a very stable ISO. When the ISO is burned to a CDrom and then booted on your machine of choice it will install a rock solid world class version of Asterisk. The ISO does not need frequent updating as we have chosen to compile the software on the fly as needed. Later there will be scripts available to manage your updates either automatically or manually. One thing you won t find is bloat! We have heard that bloat is simply extra space used by programs but we beg to differ. Many installations like to install the kitchen sink which does tend to slow the machine down significantly and use up extra hard drive space. If you want to install a crm product and we have written a script for it you simply download the script and run it. No muss no fuss! We feel our minimalist approach with the ability to add as much or as little as you want it superior. INSTALLING PBX in a Flash Initially you will have to decide if you want to install it to a real computer or a vmware virtual one. Either way will work but this document will concentrate on installing PBX in a Flash onto a real as opposed to virtual computer. Once you have downloaded the iso image from please burn it to a cdrom. Please the cdrom into the computer you want to install PBX in a Flash to and reboot the system.

Initial Configuration Genzaptelconf As it sits when PBX in a Flash has done the final reboot Zaptel is not configured. This can lead to problems so let us configure and run genzaptel.conf 1.

13 Initial Configuration Genzaptelconf As it sits when PBX in a Flash has done the final reboot Zaptel is not configured. This can lead to problems so let us configure and run genzaptel.conf 1. Log into the CLI (Command Line Interface) as user root using the password you typed in during the install. 2. This is the initial login screen and tells you about your system ip address and how to get help.

4. Now we need to install a special editor. While PBX in a Flash comes with nano preinstalled I prefer joe. This editor is a clone of WordStar and is designed for use in a Linux environment.

Using the arrow keys scroll up and down and ensure that a # is placed in the front of each of the entries in the file. If you have one of the cards listed please be sure to uncomment it.

If you want to exit joe without saving hold down the Ctrl key and tap the C key You should see the screen below if the file was saved correctly Copyright 2007 Thomas A.

15 7. Now we can run genzaptelconf to correctly configure zaptel. In the CLI type genzaptelconf and then tap the ENTER key. If you get errors the first time you run genzaptelconf simply rerun it and you should see a screen similar to the one above. Copyright 2007 Thomas A. King All Rights Reserved Page 15

16 8. You can verify it by typing zttool in the CLI and then tapping the ENTER key. You should see a screen similar to the ones below. This essentially shows that the ztdummy is configured correctly. When you don t have a hardware card installed the ztdummy is required as a timing source. Network Configuration This should be one of the easiest parts of the install however some have reported a non sticky IP address which could cause problems so we will outline a workaround for it. 1. Gather the information you will need to create a static address. Have a look at the table below and fill it out prior to going on to step 2. If you are going to use a DHCP IP address skip this section entirely. A short explanation of each item is below the table. Copyright 2007 Thomas A. King All Rights Reserved Page 16

You will need to look at your router configuration pages to get this number. 2. Log into the CLI using the root user and type netconfig and then tap the ENTER key 3. You should see a screen similar to the one below Using the left or right arrow select the Yes button and then tap the ENTER key Copyright 2007 Thomas A. King All Rights Reserved Page 17

19 7. Now let s test our connection type ping and then tap the ENTER key. You should see something similar to the screen below After you see a few lines of reply hold down the Ctrl key and then tap the C key. You have now set up a static IP address. If you see anything else than the screen above try rebooting the computer using Step 5 and try Step 7 again. Copyright 2007 Thomas A. King All Rights Reserved Page 19

21 APPENDIX TWO Choosing a password Passwords used by PBX in a Flash can be of any length and are both case and punctuation sensitive. We recommend using at least eight characters, some of which are punctuation marks or other special keyboard characters. Shorter and simpler passwords weaken your defenses. For example, the password JOHNJOHN is quite weak, particularly if your name is John. J_O%H#N@ is slightly better, but it still contains elements of your name. A password such as F#LLL&*_ would be a better choice (Note: Please do not use this example). Lastly, try to use a password you will remember, but which others will not guess (easier said than done), and never, never, NEVER write your password down! We suggest using an easily remembered scheme such as the following that is almost impossible to guess: 1. Choose a nursery rhyme or other saying that you can remember. 2. Use the first letter of each word, either upper or lower case, in sequence to make up the password. 3. For words such as and, at, number or star use the symbols on the top row of the keyboard ( # or *. 4. For numbers use the actual number key rather than the word. 5. Use punctuation where appropriate. 6. For example, Hey Diddle Diddle, the Cat and the Fiddle! would generate the following password: HDD,tC&tF!. (Do not use this example as your password) Copyright 2007 Thomas A. King All Rights Reserved Page 21
