11-28-11 Astrerisk is a free call process, provides support for cards like T1 - it acts like a gateway, or you can employ a service (server to act as the card or gateway) It has become much better over the last five years and has been aroud for 7 or 8 but was no very stable in the beginning. You will find it built into most open source services. You can get asterisk to work on windows but it is not designed for that. The 7900 series of cisco phones work well with asterisk and can get a 7960 for around 20 bucks on ebay.

We will be using Oracle's VirtualBox to download Asterisk to. You will need to create a storage space on your D drive. Make a new folder with your name and semester "Name-FA11" then close.

Next open up VirtualBox settings and under general in the default box find the folder you just made and click ok. Your information will now be saved there.

Next create a new virtual machine by clicking on new machine under OS click on Linux, click next, under RAM use 768 , click next, create new hard disk, click next, VDI, next, Dynammically allocated, next location Astersiks server, default, next, then click create. You should now see that your VM has been created.

You will now nee to change the settings under the network by simply clicking on Network and under network click on adapter and on attatched and change to bridged.

    • Next under storage CD/DVD Drive: click icon beside arrow change to choose a virtual disk CNT files under Linux then Ubuntu 10.10. asterisk tty1

You will get a couple of warnings, click on through them. Under language choose your language (English is the only one Franske will have support for) US, enter, under keyboard click no, enter, enter, it will the start to load. Under hostname use Asterisk, enter, yes, enter, enter, under partition move to yes click continue. Make changes to disks move to yes, continue. The base system will now be installed. enter your name in lowercase, password cisco, cisco again yes, no for encrypting and down arrow for no http proxy continue and it will continue installing choose no automatic updates. Under software selection leave them all blank by using tab key to tab through to select continue after installation select yes to install bootloader. Finish by clicking on devices and click on CD/DVD and make sure there is no check mark beside ubuntu. then click continue

Type your name and password that you entered You are not automatically admin to become the admin you have to enter: sudo bash You will see a # to confirm that you are now admin. We will now edit a file by typing: nano /etc/apt/sources.list (nano is the text editor and etc is the file) Click control W US. archive.ubuntu.com Under replace with: enter mirror .rit.edu then repeat control w and change security.ubuntu.com with the mirror.RIT.edu Update by typing aptitude update, enter aptitude full-upgrade, enter, click enter for yes and update starts. After update it will say Current Staus: 0 updates [-94] We will the type: aptitude install asterisk atfpd dhcp3-server enter 001 for USA country code and click continue If there are errors (and ther will be) type: aptitude update enter install aptitude update enter

to restart type: shutdown -r now

and try reinstalling if there are still errors, you will need to log back in and refollow steps to update

We should be able to program settings for 7960 phone nano sip.com nano extensions.com

Notes 2011 11 30

The problem with the asterisk install was the age of the operating system. The fix is to upgrade the Ubuntu OS to a later version that is compatible with the current asterisk distribution.

The upgrade process includes the following. 1. login 2. become root via the command

   sudo bash

3. Edit the file, /etc/apt/sources.list. Change the phrase, maverick, to the phrase, nantty, on every line.

   The vi command phrase is :1,$s/maverick/nantty/g

4. Update via the command

   aptitude update

5. Install the upgrade via the command

   aptitude full-upgrade
     Accept this solution:   Answer Y to every prompt
     Click OK for the openbsd-inetd cron atd upgrade
     Click OK for the cron atd upgrade

Login w/: sudo bash Finished updating with replacing the maverick file with natty and updated again

Aptitude update
Aptitude full-upgrade

At the Configuring libc6 screen: enter, enter After updating type in:

asterisk
cd/etc/asterisk
ls

We then will go to the file tftp file editor

nano /etc/default/atftpd 

A file should come up with [Read 2 lines] if not update tftp

aptitude install atftpd

add to the beginnng:

--daemon --port69

Add to the end:

  • ! exclamation marks = enter
  • nano = edit

Unhook ethernet & login

cd/tftpboot
tftpboot#wget ftp://10.1.11.36/tftpboot/*
ls    (to show listing)
etc/network/interfaces
cp/etc/dhcp3/dhcpd.conf /etc/dhcpd.conf    (to copy config file from dhcpd3 to dhcpd)


Once your plugged back in and have pc and phone plugged into a poe switch


ifup eth0
ifconfig

Use the following command to see what is happening in real time and control c to get back

tail -f /var/log/syslog
cntrl c
/etc/init.d/isc-dhcp-server start

If you encounter any errors with your configuration file you can edit it by going to:

nano /etc/dhcp/dhcpd.conf
tail /var/log/syslog   (To show tail end of the log


Anytime you need to make a change on the phone you will need to unplug and go through the start up process again

/etc/default/atftpd
/etc/inetd.conf


Go to the line that starts with tftp go to end of line that and change /srvtftp to tftpboot


ps aux | grep tftp
/etc/init.d/openbsd-inetd restart 
ps aux | grep tftp


If the srv is still up you have kill the line


nano XMLDefault.cnf.xml    (for editing)

Phone will "Phone Unprovisioned" when it is requesting configuration

cd/tftpboot
tail/var/syslog

make a copy of the SIPmacaddress.cnf

cp SIPmacaddress.cnf SIP(insert mac address here)
nano /etc/asterisk/sip.conf

Edit file:

[phone2line1]
type=friend
context=local_pod
callerid="phone2line1" <5002>
host=dynamic
dtmfmode=rfc2833
nano SIP(insert mac address here and use all capital letters).cnf
nano SIPDCefault.cnf

Change the proxy addresses to your computer address Unplug phone and let configuration files reload and reconnect with the following command

asterisk -rcvvvvvvvvvvvvv
sip show peers
cp SIPmacaddress.cnf

Edit file by changing phone1 to phone2 on all instances:

"phone2line1"
"phone 2"

Unplug phone and plug back in, after you make changes in asterisk you need it to reread the configuration

asterisk -rcvvvvvvvvvvvvv
reload
sip show peers   (to show neighbors) 

Now we need to set up a dial plan that allows the phones to communicate A key file is called extensions.conf where all kinds of config files are stored, one of the files is called [demo] which we will try to get to work.

nano /etc/asterisk/extensions.conf
[local_pod]
exten => 5001,1,Dial(SIP/phone1line1)
exten => 5002,1,Dial(SIP/phone2line1)
asterisk -rcvvvvvvvvvvvvv
reload

Now can pick up phone and check for dialtone

nano /etc/asterisk/extensions.conf

[demo] to ring a "dummy" line

exten =>6001,1,Goto(Demo,s,1)

You can create another extension and change the caller id by going back to the exten file and entering commands:

exten =>6001,1,Doto(demo,s,1)
exten =>6002,

Now lets see if we can get voicemail working by going to: voice-info.com google "trixbox"
