Preparing the System¶

Hostname¶

If the hostname was not set during First Boot you can modify /etc/sysconfig/network.

# /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=invttmtjwx03.tmtj.invite-comm.jp

Client Routing¶

Create a routing file in /etc/sysconfig/network-scripts for client facing interfaces. For example eth2 would use /etc/sysconfig/network-scripts/route-eth2 to route to the client network.

# /etc/sysconfig/network-scripts/route-eth2
192.168.0.0/24 via 172.16.0.10
10.0.0.0/24 via 172.16.0.10

Tip

This is the best point to run sys-unconfig and create the clone of the virtual machine. Additional settings are specific* the each virtual machine.

Prepare the Asterisk Template¶

Find a suitable template.¶

Find an MCAT configuration that performs a role similar to the new MCAT server. We’ll use invttmtjtest in the table below, to create invttmtjwx03 and invttmtjwx04.

invttmtjtest	Example Template
invttmtjwx03	Sample Server
invttmtjwx04	Sample Clone

cd /home/mcat
svn cp invttmtjtest invttmtjwx03
svn commit -m "Base Config invttmtjwx03" invttmtjwx03

Tip

Create the clone after making basic modifications to the asterisk configuration.

svn cp invttmtjwx03 invttmtjwx04
svn commit -m "Base Config invttmtjwx04" invttmtjwx04

Replace Symlink¶

rm /etc/asterisk
ln -s /home/mcat/invttmtjwx03/etc/asterisk asterisk
ls -la /etc/ | grep ^l | grep asterisk

asterisk -> /home/mcat/invttmtjwx03/etc/asterisk

Modify the SIP Settings¶

# /etc/asterisk/sip.conf
[INVTTMTJWX03]
username=INVTTMTJWX03
host=192.168.32.26 ; Client Host IP
accountcode=INVTTMTJWX03-MCAT ; From WX03 to MCAT
[mcat](!)
accountcode=MCAT-INVTTMTJWX03 ; MCAT to WX03

Modify the Dial Plan¶

# /etc/asterisk/extensions.conf
[INBOUND]
exten => _X.,n,Dial(SIP/INVTTMTJWX03/${EXTEN})
