5.	Compilação do Asterisk.

		cd /usr/src/asterisk

	
		cd dahdi-linux-complete-2.10.2-rc1+2.10.2-rc1
		make clean
		make all
		make install
		make config
		cd ..
		

		cd libpri-1.4.15
		make clean 
		make 
		make install 
		cd ..
		
		cd  asterisk-11.25.3
		./configure
		make menuselect (selecionar o modulo app_meetme em aplications)
		make 
		make install 
		make config 
		make samples 
		cd ..
		
		
		/etc/init.d/asterisk stop

6.	Copiar do diretório de tradução os subdiretórios para 

		cp -r /usr/src/asterisk/sounds/pt_BR /var/lib/asterisk/sounds/pt_BR
		cd /var/lib/asterisk/sounds/pt_BR
		wget http://sac.teletec.com.br:81/asterisk/11_debian_8.1/callback_msg.wav

		adduser asterisk
		adduser asteriskconf
		
		editar o arquivo /etc/passwd e conceder permissão de root para o usuario asterisk
		
8.	Alterar permissões para que o asterisk rode no usuário asterisk 

		cd /etc/init.d
		wget -q http://sac.teletec.com.br:81/asterisk/11_debian_8.1/asterisk -O /etc/init.d/asterisk
		wget -q http://sac.teletec.com.br:81/asterisk/11_debian_8.1/functions -O /etc/init.d/functions
		chmod 744 asterisk
		chmod 744 functions
		systemctl daemon-reload
		
		cd /
		chown -R asterisk:asteriskconf /etc/asterisk
		chown -R asterisk:asteriskconf /usr/lib/asterisk
		chown -R asterisk:asteriskconf /var/lib/asterisk
		chown -R asterisk:asteriskconf /var/log/asterisk
		chown -R asterisk:asteriskconf /var/run/asterisk
		chown -R asterisk:asteriskconf /var/spool/asterisk
		chown -R asterisk:asteriskconf /etc/odbc.ini
		chown -R asterisk:asteriskconf /etc/odbcinst.ini
		chown -R asterisk:asteriskconf /etc/rc.firewall_ipv4
		chown -R asterisk:asteriskconf /etc/rc.firewall_ipv6
		chmod -R u=rwx,g=rwx,o= /etc/asterisk

		chmod -R u=rwx,g=rwx,o= /var/lib/asterisk
		chmod -R u=rwx,g=rwx,o= /var/log/asterisk
		chmod -R u=rwx,g=rwx,o= /var/run/asterisk
		chmod -R u=rwx,g=rwx,o= /var/spool/asterisk
	 	chmod -R u=rwx,g=rwx,o= /etc/odbc.ini
	 	chmod -R u=rwx,g=rwx,o= /etc/odbcinst.ini
		chmod -R u=rwx,g=rwx,o= /etc/rc.firewall_ipv4
		chmod -R u=rwx,g=rwx,o= /etc/rc.firewall_ipv6

9.	Executar provisionamento das configurações de domínio para alterar arquivos de configuração em /etc/asterisk


12.	Startar o serviço do asterisk

	/etc/init.d/dahdi start
	/etc/init.d/asterisk start

	
13. Caso esteja utilizando placas (Digium/Khomp/Digivoice,etc), verificar se a placa não esta compartilhando IRQ atraves do comando lspci -v e lspci -vb
    As placas não podem compartilhar IRQ, um dos principais problemas é a queda de ligações.
    Desabilitar tambem o power management da bios do servidor e remover os pacotes instalados no servidor referente a este serviço

	/etc/init.d/acpid stop
	apt-get remove acpid
	apt-get remove exim4 exim4-base exim4-config exim4-daemon-light
	apt-get purge acpid
	apt-get purge exim4 exim4-base exim4-config exim4-daemon-light
	apt-get remove apache2-utils
	update-rc.d -f exim4 remove
   	
14. Forçar o debian a carregar o modulo ip_conntrack na inicialização.

	pico /etc/rc.local
	/sbin/modprobe ip_conntrack 
	/etc/rc.firewall_ipv4
	/etc/rc.firewall_ipv6

15. para acertar o timezone

	dpkg-reconfigure tzdata
16. Desabilitar /var/mail

	dpkg-reconfigure exim4-config


17. Configurar sudores
	#
	# This file MUST be edited with the 'visudo' command as root.
	#
	# Please consider adding local content in /etc/sudoers.d/ instead of
