CENTOS 6.8 and Asterisk 11.x Install (with dahdi card)

 

---After the install if dahdi is not present in the asterisk cli then do the following:

service asterisk stop
service dahdi stop
--Go to Dahdi directory
make Install
make config
--Go to Dahdi tools directory
make install
reboot
--Go to Asterisk Addons directory
./configure
        or ./configure --libdir=/usr/lib64 (for 64bit system)
make install
--Go to Asterisk 1.6.x.x directory
./configure
        or ./configure --libdir=/usr/lib64 (for 64bit system)
make install
make config
service asterisk stop
service dahdi stop
service dahdi start
service asterisk start

---end After the install if dahdi is not present in the asterisk cli then do the following:

CENTOS 6.8 and Asterisk 11.x Install Part 1

1. Download CENTOS 6.8 Minimal Install ISO
2. Burn to CD/DVD
3. Boot PC on CD/DVD
4. Install OS
5. After Install reboot
6. Verify hostname
            # hostname
7. Setup Network
             # cd /etc/sysconfig/network-scripts

2. change ifcfg-eth0 file to reflect like the following example below. Your UUID and HWADDR should not be changed. Below is just an example.

DEVICE=eth0

HWADDR=00:12:3F:B8:CD:FF

TYPE=Ethernet

UUID=d960e22d-214f-450c-b017-a3ad590bb225

ONBOOT=yes

NM_CONTROLLED=no

BOOTPROTO=none

IPADDR=x.x.128.8

NETMASK=255.255.255.0

GATEWAY=x.x.128.1

BROADCAST=x.x.128.255

DNS1=x.x.1.10

DNS2=x.x.1.12

8. Restart network services

# services network restart

9. Run ifconfig, ping from remote machine to server, and ping google.com from server to verify. Now you can ssh in from your workstation
10. update new install

# yum update –y

11. Disable SELinux

# vi /etc/selinux/config
and chang to:

SELINUX=disabled

12. Stop iptables

# service iptables stop

13. Prevent iptables from auto starting

# chkconfig iptables off

14. Reboot

# reboot

Setting up NTP in Centos 6.8

 First we need to make sure we have the correct date, time, and timezone. You can verify with:

# cat /etc/localtime

Set your time zone with (for Phoenix AZ USA)

#cp /usr/share/zoneinfo/America/Phoenix /etc/localtime


Now check date

# date
Sun Mar 29 01:10:44 MST 2015

You can verify this at the hardware level with:

# hwclock -r
Sun 29 Mar 2015 01:13:51 AM MST  -0.156631 seconds

If  these are incorrect then we can set the OS first and then update the hardware with the date command. The syntax is: date "day month year hh:mm:ss" So if we wanted to change this to March 2 2015 at 1:00pm we would use:

# date -s "2 MAR 2015 13:00:00"

When we have the date correct in the OS we can update the hardware with:

# hwclock -w

Now that we have the correct date and time lets install and setup ntp. First lets install ntp if not already installed.

# yum -y install ntp*

Next edit the the ntp.conf file so we are using the correct time servers.

# vi /etc/ntp.conf

I usually use the public servers from the pool.ntp.org project of:
server 0.centos.pool.ntp.org iburst
server 1.centos.pool.ntp.org iburst
server 2.centos.pool.ntp.org iburst
server 3.centos.pool.ntp.org iburst

After you have those in lets start the service and make sure it is on in startup.

# service ntpd start
Starting ntpd:                                             [  OK  ]
# chkconfig ntpd on

Now lets verify the setup by looking at our peers.

# ntpq -p

CENTOS 6.8 and Asterisk 11.x Install Part 2

1 Installation of Basic Dependencies

Asterisk 11.15.0 requires some prerequisite dependencies. Here is the command line to install them:

# yum -y install gcc ncurses-devel libtermcap-devel kernel-devel gcc-c++ newt-devel zlib-devel unixODBC-devel libtool make wget libuuid-devel libxml2-devel sqlite sqlite-devel

# yum -y install kernel-devel-$(uname -r)

# yum -y groupinstall "Development Tools"

# reboot

2 Downloading Your Asterisk Source Code

Move to directory /usr/src by given command:

# cd /usr/src/

Now download the Source Code tar balls using these commands (one by one or at a time):

# wget http://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/dahdi-linux-complete-2.6.3-rc1+2.6.3-rc1.tar.gz

# wget http://downloads.asterisk.org/pub/telephony/libpri/libpri-1.5.0.tar.gz

# wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-11-current.tar.gz

3 Extraction of Downloaded Files

Extract the downloaded tar balls to their corresponding directories using:

# tar -zxvf dahdi-linux-complete*
# tar -zxvf libpri*
# tar -zxvf asterisk*

4 DAHDI Installation

DAHDI (Digium Asterisk Hardware Device Interface) can be installed using the command line:

# cd /usr/src/dahdi-linux-complete*
# make && make install && make config

5 LibPRI Installation

In order to enable your BRI, PRI and QSIG based hardware, you will be needing PRI Library or LibPRI. You can install these libraries using:

# cd /usr/src/libpri*
# make && make install

6 Changing Asterisk Directory

Now you have to move back to the Asterisk Installation Directory:

# cd /usr/src/asterisk*

7 Running Configure Script for Asterisk

At this point, you need to know your CentOS 6 Architecture (32 or 64 Bit). In many cases you are aware of it. In case you are not, try this command:

# uname -a

For 32 Bit, you will be getting response like:

2.6.18-238.12.1.el5 #1 SMP Tue May 31 13:23:01 EDT 2011 i686 i686 i386 GNU/Linux

For 64 Bit, system will respond with something like:

2.6.18-238.19.1.el5 #1 SMP Fri Jul 15 07:31:24 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux

Based on your OS Architecture, go ahead with these commands for Asterisk Configuration Script. During the process the asterisk build menu may be displayed. Simply press the esc key one time to exit and continue the install.

For 32 Bit:

# ./configure && make menuselect && make && make install

For 64 Bit:

# ./configure --libdir=/usr/lib64 && make menuselect && make && make install

8 Installing Sample Files

Install Sample Files using:

# make samples

Once done, add the Asterisk Install Script in directory /etc/init.d/ using:

# make config

9 Starting DAHDI

To start DAHDI Device Drivers, use:

# service dahdi start
Loading DAHDI hardware modules:
  wct4xxp:                                                 [  OK  ]
  wcte43x:                                                 [  OK  ]

  wctc4xxp:                                                [  OK  ]
  xpp_usb:                                                 [  OK  ]

Running dahdi_cfg:                                         [  OK  ]
 

10 Start Asterisk

Finally, start Asterisk:

# service asterisk start

11. Reboot

# reboot

CENTOS 6.8 and Asterisk 11.x Install Part 3 setting up DAHDI

I am using the Digium Wildcard TE110P T1/E1 Card into an Adtran 908E. The Adtran has a SIP trunk to a CLEC. The T1/PRI card in the Asterisk server is used deliver 23 phone channels (1 channel out of the 24 is used for clocking) to/from the Adtran/Asterisk.

1 Generate system.conf file by running:

# /usr/sbin/dahdi_genconf

My /etc/dahdi/system.conf has the following

# Autogenerated by /usr/sbin/dahdi_genconf on Sun Dec 28 23:00:55 2014

# If you edit this file and execute /usr/sbin/dahdi_genconf again,

# your manual changes will be LOST.

# Dahdi Configuration File

#

# This file is parsed by the Dahdi Configurator, dahdi_cfg

#

# Span 1: WCT1/0 "Digium Wildcard TE110P T1/E1 Card 0" (MASTER) ESF/B8ZS

span=1,1,0,esf,b8zs

# termtype: te

bchan=1-23

dchan=24

echocanceller=mg2,1-23

# Global data

loadzone        = us

defaultzone     = us

As it says the above file, “Autogenerated by /usr/sbin/dahdi_genconf”. And “If you edit this file and execute /usr/sbin/dahdi_genconf again, your manual changes will be LOST.”

Now make sure your /etc/asterisk/chan_dahdi.conf has the following, add to end of file: (This will create the channels for you)

context=from-test

switchtype=national

siganling=pri_cpe

group=1

channel => 1-23
