Picture of Using berofix with asterisk
This instruction assumes that you can reach the berofix card in your network.
The example uses a berofix card with one bf4S0 Lineinterface. 

Step 1: Establish SIP connection

Picture of Establish SIP connection
The first thing you have to do when you try to bring your berofix card up and running with the Asterisk, is to establish the SIP connection between them.
To do so simply add the following lines to the "/etc/asterisk/sip.conf" to create a new SIP friend/peer:

[berofix]
type=friend
secret=berofix
host=10.0.0.2
allow=all
canreinvite=no
context=from-sip



In the "/etc/asterisk/extensions.conf" you need to add a context "from-sip" like:

[from-sip]
exten => _X.,1,Playback(tt-monkeys)



So every call from berofix will be routed to Playback(tt-monkeys).
If you want to send calls to berofix you can simply use the following dial statement:

exten => _0X.,1,Dial(SIP/99${EXTEN:1}@berofix)
exten => _0X.,n,hangup



To make this work you need to reload the configs on the asterisk cli:

asterisk -rx "reload"
