As part of my VoIP adventure game, I need to set up a VoIP number, but thankfully my ISP (iiNet) provides a free VoIP number to NBN customers, so that was covered. Next up I needed a virtual PBX, I went with Asterisk. This was an easy install on Ubuntu 18.04, just:
sudo apt install asterisk
Of course, installing software is much different from configuring it for use, so let me just preface this with describing some of my experience:
Most of the frustration really just comes from getting my VoIP number registered. For iiNet users, there’s some settings you can use available on their website. However be warned, getting them into Asterisk is slightly harder. You’ll want to modify
/etc/asterisk/sip.conf and add the following straight under your
register => XXXXXXXXXX@iinetphone.iinet.net.au:YYYYYYYY:XXXXXXXXXX@iinetphone/XXXXXXXXXX
Make sure to replace the XXXXXXXXXX with your Netphone number (including state code) and the YYYYYYYY with your Netphone password.
Then at the bottom of
sip.conf add the following:
[iinetphone] host=sip.wa.iinet.net.au fromdomain=iinetphone.iinet.net.au fromuser=XXXXXXXXXX username=XXXXXXXXXX defaultuser=XXXXXXXXXX context=inbound disallow=all ;allow=g729 allow=ulaw allow=alaw insecure=port,invite canreinvite=no secret=YYYYYYYY type=friend nat=yes qualify=yes
Make the same replacements, but also change
sip.wa.iinet.net.au, replacing the state (second section) with your home state.
Now open up
/etc/asterisk/extensions.conf and find the section labelled
[default] and change it to the following:
[default] include => inbound
Then append the following to the end of the file:
[inbound] exten => XXXXXXXXXX,1,Answer() exten => XXXXXXXXXX,1,Wait(5)
Replace XXXXXXXXXX with your Netphone number once more.
Make sure you restart Asterisk (
systemctl restart asterisk.service) and you should be able to call the number. Expect it to answer, wait 5 seconds, then immediately disconnect.
Now you can do whatever you want to configure it to answer, send to a softphone extension or a VoIP handset, etc.
