editors
The config files of Asterisk are located in /etc/asterisk/
Editing those files with the installed editor vi, is rather tedious. Therefore we installed Emacs to do the editing. Since Trixbox is based on CentOS, it is possible to use the CentOS RPM's to install Emacs.
The 2 RPM's needed for Emacs are located at the following URL's:
ftp://ftp.nluug.nl/pub/os/Linux/distr/CentOS/4.4/os/i386/CentOS/RPMS/emacs-common-21.3-19.EL.4.i386.rpm ftp://ftp.nluug.nl/pub/os/Linux/distr/CentOS/4.4/os/i386/CentOS/RPMS/emacs-nox-21.3-19.EL.4.i386.rpm
Using the program wget, it is possible to download these. After downloading, the RPM's can be installed with "rpm -i". We also created some smaller URL's, which is easier to type ;)
mkdir install cd install wget http://turl.nl/99 wget http://turl.nl/100 rpm -i emacs-common-21.3-19.EL.4.i386.rpm rpm -i emacs-nox-21.3-19.EL.4.i386.rpm
Connecting to existing systems
Connecting Asterisk to an existing telephone network. This is called a PSTN call (Public Switched Telephone Network) Asterisk can be connected to a SIP or IAX provider (like VoIPBuster) or by using a (voice-)modem-card of Zaptel-card in de Asterisk-server.
VoIPBuster
A few config-files have to be changed in order to get the system to work with VoIPBuster
Adding to sip.conf:
[voipbuster] type=peer host=sip1.voipbuster.com username=GEBRUIKERSNAAM secret=WACHTWOORD notransfer=yes insecure=very externip=JEEXTERNEIP context=voipbuster-out
register => GEBRUIKER:WACHTWOORD@sip1.voipbuster.com
At this point there is a (peer) connection active. The only thing left is making it work.

include => voipbuster-out
exten => _06XXXXXXXX,1,Dial(SIP/${EXTEN}@pstn-spa3k,60,)
exten => _06XXXXXXXX,2,Congestion
Previous code will operate as follows: All extensions of 10 digits, starting with a "0", will replace the leading zero with "0031" (Dutch country-code), which is needed for using VoIPbuster.
7500 is the voicemail
9999 is de incomming line, for Voipbuster-IN. At this moment, this does not yet work.
06 numbers are routed through the installed modem-card, because this is cheaper than using VoIPbuster.
Example of SIP.conf:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 [9999] type=friend language=nl host=dynamic context=home secret=WACHTWOORD mailbox=9999 dtmfmode=rfc2833 disallow=all allow=ulaw [5555] ; If you're using Asterisk, this goes into the Incoming settings ; For your Trunk type=friend host=dynamic ; If using Asterisk@home, change the below line to context=from-internal context=home secret=WACHTWOORD dtmfmode=rfc2833 disallow=all allow=ulaw insecure=very [pstn-spa3k] ; If you're using Asterisk, this section goes into the Outgoing Settings ; for your trunk. type=peer auth=md5 host=134.145.134.18 port=5061 secret=WACHTWOORD username=asterisk fromuser=asterisk dtmfmode=rfc2833 ; If using Asterisk@home, change the below line to context=from-internal context=home insecure=very
If all went well, it is now possible to make a call using VoIPBuster. Using a free account, the call is limited to 2 minutes.
It is also possible to get a telephone number with VoIPbuster. See their site for more info.
