WM: We disabled this because of a reported problem on Amazon EC2. But it’s easy to enable it again. Just issue the following commands. Or you could add a subnet directly by editing /etc/iptables/rules.v4 and restarting IPtables. Just be sure to use our iptables-restart script so that IPtables doesn’t end up disabled if you make a coding error!
sed -i 's|#-A INPUT -s 172.16.0.0/12|-A INPUT -s 172.16.0.0/12|' /etc/iptables/rules.v4
iptables-restart


[WM: Take another look at the tutorial. Did you set up an admin password??]

[WM: Not a good idea to do web hosting and VoIP telephony on the same box.]

[WM: It’s still experimental but Josh North appears to have tamed the fax beast on Ubuntu. Here’s the link.]

[WM: Visit the PIAF Forum. There are numerous ways.]

Unfortunately, I tried to run the install on a Digital Ocean droplet that I host my web applications on and ran into some problems.

I tried the brand new Vultr.com hosting solution, fired up a new VPS for 5 bucks and better specs than D.O., and voila — the install worked flawlessly.

FYI, the problem I ran into on D.O. had to do with PHP loading a blank page when visiting my IP. Probably because of my own preconfigurations though.

Thanks again.

I see above some people are confused between updates and upgrades.

After installing 14.04 you recommend the following command as root:
apt-get update && apt-get upgrade -y && reboot

This works fine for those using an older version of ubuntu.

However, when 14.10 is released in October, the upgrade typically breaks lots of stuff, and very likely will break Incredible PBX also.

I suggest you put a caveat about the October upgrade to 14.10 – and give people a heads up.

[WM: Thanks, Anthony. Still an Ubuntu newbie here. We’ll update the article and remove the upgrade component. We initially had problems, but it may have been because we didn’t run update or upgrade. In any case, you’re absolutely right. We’ve learned the hard way with CentOS upgrades. No need to reinvent the wheel.]

Thanks for the tip. It seems to work. That one was driving me crazy..

Looking through the install script – it downloads knockd from the debian repos. Why not just use the Ubuntu trusty universe repo?

No need then to dl libpcap and test for 32/64 bit..

[WM: Thank you for the tip! As time permits, we’ll rework it to incorporate your suggestion.]

First, thank you for developing this ubuntu install of incrediblepbx.. I much prefer this over the old CentOS implementation.

I’ve been messing with this ubuntu installation on a cubox-i2ex for my simple soho installation. It’s looking promising..

While I’ve been studying the hiccups on the cubox-i, I’ve been using the ubuntu preview on an x86 box – two providers, handful of extensions.. Been pretty good so far.

One problem on BOTH platforms that is driving me nuts: the install scripts breaks the OS reboot/shutdown. Short of cycling power, I can’t reboot or shutdown either the x86 or arm boxes. Anyone experience this? Suggestions?

[WM: Try this!]

cd /root
wget --no-check-certificate https://raw.githubusercontent.com/joshnorth/UbuntuPIAF/master/FixIncrediblePBXMySQL.sh
chmod +x FixIncrediblePBXMySQL.sh
./FixIncrediblePBXMySQL.sh

[WM: Download and untar Incredible Backup 11 for Ubuntu, make a backup, and copy it from /tmp to your desktop. Install the newest version, copy the backup image to /tmp, and run /root/incrediblerestore.]

[WM: Thanks, Josh. Wrestling with Incredible Fax would be a huge help. Come join the forum!]

[WM: Thanks for the heads up, Josh. We’ll have a look. Running a little low on people with paddles at the moment, but we’ll get it squared away… soon. Ubuntu is still very much a testing platform. If you need a production-ready system, switch to Incredible PBX with PIAF-Green and FreePBX 2.11 on the CentOS 6.5 platform.]

In between the above stages, I get a load of questions I don’t know the answer to:

‘Enter your USERNAME to connect to the ‘asterisk’ database:
Enter your PASSWORD to connect to the ‘asterisk’ database:
Enter the hostname of the ‘asterisk’ database:
Enter a USERNAME to connect to the Asterisk Manager interface:
Enter a PASSWORD to connect to the Asterisk Manager interface:’

Is this normal behaviour, and if so, what am I supposed to be entering?

[WM: Sounds like you’re either using the wrong version of Ubuntu or you skipped the initial (required) update, upgrade, and reboot steps. Follow the tutorial exactly, and you shouldn’t have any problems. Still works as advertised for us.]

Still don’t understand why setting up and maintaining a ppa repository would not be a better approach. Yes, you mentioned the preference to compiling Asterisk from source but is it really a smart tradeoff to lose all the great work a package manager can offer for free – fast security updates included?

[WM: Nothing in our build precludes enabling automatic security updates with Ubuntu. And Incredible PBX handles automatic security updates for Asterisk and any other problems we spot.]

[WM: It is still available, but the license has changed a bit. Read the Adding Speech Recognition tutorial in this article. It will walk you through setting it up. Did you skip the first step??

I cannot run (or even find) the asterisk binary but any attempt to rerun the installation scripts results in a message "Incredible PBX is already installed."

Can I recover from this?

[WM: You didn’t mention which cloud provider you were using. Works flawlessly on Digital Ocean. We would need a good bit more information to troubleshoot what went wrong. That’s what the PIAF Forum is there for. We install the LAMP stack as part of the Incredible PBX installation procedure so that’s not the problem. You can attempt to rerun the installer and see where the install is failing. Just delete /etc/pbx/.incredible, and you’re good to go. ]

/etc/php.ini:

short_open_tag = On

Restart Apache and done.

Glad to see all my efforts go to good use!
