Backup of an Asterisk system

Tags:

This quick and dirty shell script will backup the most important stuff of an Asterisk installation and create one big file made up of many smaller files. I assume you have an Asterisk box with a quite standard installation path and XC-AST installed too (therefore you want to backup Tomcat and MySQL). 

ora=`date '+%Y.%m.%d-%H.%M.%S'`

tar zcf etc-asterisk-$ora.tar.gz /etc/asterisk
tar zcf var-log-asterisk-$ora.tar.gz /var/log/asterisk
tar zcf var-lib-asterisk-$ora.tar.gz /var/lib/asterisk
tar zcf var-spool-asterisk-$ora.tar.gz /var/spool/asterisk
tar zcf usr-lib-asterisk-$ora.tar.gz /usr/lib/asterisk


tar zcf var-lib-mysql-$ora.tar.gz /var/lib/mysql
tar zcf usr-local-tomcat-$ora.tar.gz /usr/local/tomcat/webapps


# make one big file of them all

tar zcf asterisk-stuff-$ora.tgz *$ora*
rm -f $ora.tar.gz
If Tomcat and MySQL are not installed, you need not backup /var/lib/mysql and /usr/local/tomcat/webapps Continue Reading...

Displaying OH323 calls

Tags:

This node is meant as a handy guide to showing ongoing OH323 calls in your Asterisk system. To make full use of this tutorial, you first have to start the Asterisk CLI, with a command like: 

asterisk -vvvvvvvvvvvvvvvvvvr
It will attach itself to the local Asterisk instance. The basic OH323 monitoring commands are all under oh323 show … oh323 show estabilished This is the basic command showing how may active connections are present in the system. Nothing to be too excited about. :-) the first line in the example is the line you enter. 
ast*CLI> oh323 show established
2 established H.323 connection(s)
oh323 show info This command exposes the details of the ongoing connections. Note how you can see the codec and the call state. (Note that from oh323 v0.6.5 onwards, the command is called oh323 show channels ). 
ast*CLI> oh323 show info
Information about active OpenH323 channel(s)
--------------------------------------------
 Num. Token                          State   Init      RX/TX   Format       Remote RTP Addr.      Local RTP Addr.

  [3 established H.323 connection(s)]
  [In-call rate: 0.00 CPS]
  [In-call block ratio: 0 %]
oh323 show vars This command shows the gory details of each call, as seen by the channel variables that can be accessed by the Asterisk dial plan. Note howw you can therefore get the caller id and the used codec. 
ast*CLI> oh323 show vars
Variables for OpenH323 channel OH323/R11380:
        OH323_CTOKEN    'ip$10.1.2.215:14979/11380'

Installing the Linksys PAP2-NA port adapter

Tags: , ,

This recipe will help installing a Linksys PAP2 port adapter to work with your Asterisk box. In this example we will imagine that the PAP2 will be on a local network with your Asterisk box and the Asterisk box will take care of all communication with the rest of the world. We imagine not to have any bandwidth problem between Asterisk and the PAP2. We also imagine that the PAP2 will have a DHCP assigned address, while the Asterisk server will have a static IP address. The Linksys does not start in DHCP client mode, so you have to activate it manually. Continue Reading...



Installing the Welltech LP302 telephone

Tags: , ,

This recipe will help installing a Welltech Lanphone LP302 telephone to work with your Asterisk box. In this example we will imagine that the LP302 will be on a local network with your Asterisk box and the Asterisk box will take care of all communication with the rest of the world. We imagine not to have any bandwidth problem between Asterisk and the LP302. We also imagine that the LP302 will have a DHCP assigned address, while the Asterisk server will have a static IP address. Right after the boot (that usually takes quite a while), the LP302 will try and obtain a DHCP address. To know the address of your phone, press “Menu” then use the down arrow to find the network configuration and press “OK”. The big display is really helpful. Open your browser and go to the obtained IP address. The default login is “root” without a password. As a basic setup, enter the following data: 

DHCP: on
SNTP: enable
SNTP server: 168.95.195.12
Time format: 24
GMT: 2
(Adjust GMT accordingly to where you are - this is for CET). As a SIP setup, enter the following data: 
Run mode: proxy
Prefix: null
Line number: 711
Line account: 711
Line password: ***
Edit your line number accordingly (keep it the same as your line account) and the password you like best. Reboot your telephone. Now edit Asterisk’s /etc/asterisk/sip.conf and add the following section: 
[711]
type=friend
secret=***
callerid="My LP302" <711>
host=dynamic
canreinvite=no
disallow=all
allow=alaw
allow=ulaw
context=sip
dtmfmode=inband
outgoinglimit=1
Calls from the LP302 will be processed in the context ‘sip’. Wait for the telephone to register and try it. With this same configuration, transfers work and so does music on hold and DTMF tones. Links: Continue Reading...
