INSTALLING AND CONFIGURING ASTERISK
=============================================
Tested with Asterisk 1.8 and 11.4.0(http://downloads.asterisk.org/pub/telephony/asterisk/old-releases/asterisk-11.4.0.tar.gz)
Install subversion:sudo apt-get install subversion
To install asterisk follow this link http://blogs.digium.com/2012/11/14/how-to-install-asterisk-11-on-ubuntu-12-4-lts/
Do one step at a time i.e make -> make install ..
Ensure to use make menuselect while installing asterisk
select format_mp3.so from make menuselect:it will load module to play mp3 files.
after 'make menuselect' do 'sudo sh contrib/scrips/get_mp3_source.sh' from asterisk source folder before make
Sample sip.conf,manager.conf,extensions.conf,logger.conf are present in asteriskConf Folder
Second way:
install Dahdi and libpri from the Digium video
do sudo apt-get install asterisk (install asterisk version 1.8)
=============================================
;Configuring /etc/asterisk/sip.conf:Create a SIP user SIP/1000abc that have context=incoming-call
;For testing purpose it is necessary to create SIP/1000abc as org.raxa.scheduler.OutgoingCallManager redirects all call to sip/1000abc
=============================================
[1000abc]
type=peer
allow=all
udpbindaddr=0.0.0.0
bindaddr=0.0.0.0
secret=yoursecret
host=dynamic
context=incoming-call
=============================================
;Configuring /etc/asterisk/extensions.conf:add two context outgoing-call and incoming call
=============================================
[outgoing-call]
exten=>100,1,SET(count=0)
exten=>100,2,AGI(agi://127.0.0.1/hello.agi?msgId=${msgId}&language=${preferLanguage}&aid=${aid}&ttsNotation=${ttsNotation})
exten=>100,3,GOTO(outgoing-call,122,1)
exten=>122,1,NoOp(Text:${message})
same=>n,NoOp(Text:${language})
;Here googletranslate goes
;now only support english
same=>n,agi(googletts.agi,${message},en)
same=>n,GOTO(outgoing-call,100,2)
Â
[incoming-call]
exten=>100,1,Answer()
same=>n,AGI(agi://127.0.0.1/hello.agi)
=============================================
;edit /etc/asterisk/manager.conf and add the following lines
;follow http://ofps.oreilly.com/titles/9781449332426/asterisk-AMI.html for further details
=============================================
[general]
enabled = yes
port = 5038
bindaddr = 127.0.0.1
webenabled=yes
allowmultiplelogin=yes
[manager]
secret = squirrel
deny = 0.0.0.0/0.0.0.0
permit = 127.0.0.1/255.0.0.0
read=system,call,log,verbose,agent,command,user,all,call,user
write=system,call,log,verbose,agent,command,user,all
=============================================
;edit /etc/asterisk/logger.conf : This is done to log information about asterisk server.Suppose your project location is
;/home/user/Project_Voice/logFiles/asteriskLog. add the following line in logger.conf
=============================================
/home/user/Project_Voice/logFiles/asteriskLog => notice,warning,error,dtmf
=============================================
INSTALLING A SIP PHONE(for testing only,need gui to work)
=============================================
install any sip phone.This is a way to install twinkle
sudo apt-get update
sudo apt-get install twinkle
For configuring twinkle:http://www.callcentric.com/support/device/twinkle
=============================================
INSTALLING GOOGLE TTS
=============================================
follow this Link:https://github.com/zaf/asterisk-googletts
for testing use the example in here :http://zaf.github.io/asterisk-googletts/
IMPORTANT: copy the googleTTS AGI as present in the code above in agi-bin not the one downloaded from above link
now give the file the write access where googletts.agi is copied. Usually /va/lib/asterisk/agi-bin. It can be confirmed by
looking the agi directory location in /etc/asterisk/asterisk.conf
do sudo chmod 777 /var/lib/asterisk/agi-bin/googletts.agi
=============================================
INSTALL ANT
=============================================
sudo apt-get -u install ant
set environment variable ANT_HOME JAVA_HOME
follow this link:http://ant.apache.org/manual/install.html
Â
=============================================
INSTALLING JDK IN UBUNTU
remove openjdk if exist
Follow this:http://www.wikihow.com/Install-Oracle-Java-on-Ubuntu-Linux (manual)
or
follow http://www.webupd8.org/2012/01/install-oracle-java-jdk-7-in-ubuntu-via.html (automatic)
=============================================
=============================================
SOURCE CODE CONFIGURATION AND DEPENDENCY
=============================================
build.xml creates a jar of the module
build1.xml creates a "fat" jar of the module i.e that jar will include all jars used by module.
AlertMessage,AlertRegistration,Database are non-runnable jar(no main function)
========================================================================
see AllJarsDependency.txt and put all required jars in projectfolder/lib
========================================================================
Â
=============================================
Steps to run the project(to be followed in the order as described)
=============================================
CREATE Database.jar
1.Database:Edit /resource/hibernate.cfg.xml according to your requirement.Set username,Password and url
2.Copy all the required libraries to lib
3.ant compile jar
CREATE AlertMessage.jar
1.Open AlertMessage
2.open english.properties and other language.properties file and fill in the require fields.
3.Copy all the required libraries to lib
4.ant compile jar
CREATE AlertRegistration.jar
1.Open AlertRegistration
2.fill the properties file
3.Copy all the required libraries to lib
4.ant compile jar
RUN AudioPlayer
1.open AudioPlayer
2.Copy all the required libraries to lib
3 fill the properties file
4.Ensure that the beep.mp3(a 2 sec sound that produces beep,even a silent tone will work) is present in the audioPlayer module.
13.ant compile jar run
CREATE SMS.jar
1. Open SMSSender
2. Copy all the required libraries to lib
3. ant compile jar
RUN Scheduler
1.open Scheduler
2.fill the properties file
3.Copy all the required libraries to lib
4.ant compile jar run
give write access to logFiles if required.
=========================================
A Note on Updater
=========================================
Updater updates patient alert for next day everyday
THIS IS ALSO DONE BY SCHEDULER
SO IF SCHEDULER IS RUNNING THERE IS NO NEED OF UPDATER
CAUTION:RUNNING BOTH SCHEDULER AND UPDATER IS A WASTE OF RESOURCE.THOUGH IT WONT AFFECT THE ALERT TABLE
Updater depends on
->AlertMessage.jar
->Database.jar
->Other common Libraries
===================================================
RUNNING REPLYSMSHANDLER SERVLET
===================================================
INSTALL TOMCAT7
->sudo apt-get install tomcat7
BE SURE TO CHECK TOMCAT IS RUNNING THE SYSTEM JAVA version otherwise it may give UnSupportedClassVersionError
Follow this link:http://askubuntu.com/questions/154953/specify-jdk-for-tomcat7
->set $catallina_home and be sure to put the same in ReplySMSHandler/build.xml
->Bydefault its /usr/share/tomcat7
->go to ReplySMSHandler Module and do ant all in console to build a warfile. Location of the build war file is :dist/sms.war
->stop tomcat sudo /etc/init.d/tomcat7 stop
->copy the war file to /var/lib/tomcat7/webapps
->start tomcat sudo /etc/init.d/tomcat7 start
The link to the servlet is http://localhost:8080/sms/incomingsms
->The link can be configured by changing web.xml
