Asterisk is a free telephone Private Branch Exchange (PBX) system. This can most easily been seen as a telephone system used to connect callers and as a sort of answering and dispatching machine. (e.g. "press 1 to speak to ..." etc)


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.

exten => _0[12345789]XXXXXXXX,2,Congestion
exten => _XXXXXXX,1,Dial,IAX2/voipbuster/0031[b]35[/b]${EXTEN}
exten => _XXXXXXX,2,Congestion
[home]
exten => 7500,1,VoicemailMain
exten => 7500,2,Hangup
exten => 9999,1,Ringing
exten => 9999,2,Dial(SIP/9999,20,T)
exten => 9999,3,Voicemail(u9999)
exten => 9999,4,Hangup
include => voipbuster-out
exten => _06XXXXXXXX,1,Dial(SIP/${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.

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.
