Monitoring your Peers (Asterisk extensions) and Trunks

25 February 2015JonAsterisk, Trixboxasterisk, extension, freepbx, pbx in a flash, sip, trixbox, trunk, VOIP

As an admin for a telephone system, possibly one of the most useful things you can do is monitoring your peers and trunks. There are 2 great reasons you should do so: 1. You can respond to and resolve issues with your system before your users know about it, and you can be in the know if someone reports “none of the phones are working” when in fact only 1 or 2 are not working 2. You can actually know when there is a problem with the system – where you otherwise might not know there is a problem until someone…

FreePBX bulk extension setup or modify

4 July 2012MattFreePBXbulk, extension, freepbx

Recently I had to set up 150 extensions and DDI numbers for a customer. Luckily they had a spreadsheet that contained all of the extension numbers and associated DDI numbers. While it would have been possible to type all of these in using the FreePBX GUI it’s obviously not desirable, and prone to errors. To create the extensions I used the ‘Bulk Extensions’ module in FreePBX. This is an ‘Unsupported’ module but worked well for me – What this module does is allows you to import a CSV file (in the correct format) to create all of the extensions. It…

FreePBX video guide Part 1 – Creating an Extension

15 December 2011MattFreePBXextension, freepbx

I’ve written quite a few guides for setting up FreePBX and A2Billing, but they can look a little daunting. So I though I’d have a go at some video tutorials. The first one is for setting up an extension in FreePBX. The system used was a clean install of a SysAdminMan virtual server. You can find more details about this here – http://sysadminman.net/sysadminman-freepbx-a2billing-hosting.html The softphone used is called Blink, this works on both Windows and Linux and you can find more details on that here – http://icanblink.com/

Asterisk upgrade breaks IAX extensions

14 September 2009MattAsteriskasterisk, Call rejected, CallToken Support required., calltokenoptional, chan_iax2.c: Call rejected, extension, iax, iax2, upgrade

If you have upgraded your version of Asterisk and find that your IAX2 extensions no longer work then the cause could be a change to the IAX protocol. This was made to resolve a security issue that could result in a denial of service attack. You will see this error in the Asterisk log file if you are suffering from this issue – chan_iax2.c: Call rejected, CallToken Support required. If you use FreePBX then Asterisk can be made to function the same as before by adding the following 2 lines to /etc/asterisk/iax_general_custom.conf – calltokenoptional = 0.0.0.0/0.0.0.0 maxcallnumbers = 16382 You…

Using DISA with FreePBX and A2Billing

DISA is great! It allows you to call in to your Asterisk server, get a dial tone, and then dial back out as if you were using a normal extension on your system. I use this lots to make cheap international calls from my mobile phone. You may also wish to route your DISA calls via A2Billing. If you’ve integrated FreePBX and A2Billing as described here it’s a simple case of changing one setting on your DISA setup in FreePBX.

Getting started with FreePBX – Part 6 Cheap phone calls using DISA and Callback

One of the great things about voip is that you can make international calls at local rates. Combine that with Asterisk/FreePBX and you’ve got the ability to make cheap international phone calls using your mobile phone. To do this we’re going to setup DISA (Direct Inward System Access). This will enable us to ring our Asterisk server, get a dial tone and then dial back out again. Then I will show you how you can combine this with callbacks if that works out cheaper for you. Installing the modules First we need to install the DISA (if it’s not installed…

Getting started with FreePBX – Part 5 Setting up an IVR

Setting up an IVR (or auto attendant, digital receptionist) is great idea for small businesses. You can have a single external number for your customers to call but then direct the call to the right department via a simple menu. First we need some extensions to put the calls through to, then we need to record the menu the caller will hear and finally setup the actual IVR. Configuring the extensions Follow the instructions in part 2 to create the extensions that you need. I have created extensions for Sales, Support and Billing

Getting started with FreePBX – Part 4 Setting up a DID number

Now we can make calls to regular telephone number via our trunk we want to setup a DID (Direct Inward Dial) number so that we can receive calls from people dialing a regular phone number. For this example I’m going to use a US number from IPKall who will provide a (free) US based telephone number. However, they are only able to do this due to a peculiarity in the law in certain states so I wouldn’t rely on the numbers being available in the future. Perfect for testing though! Singing up with IPKall First thing you need to do…

Getting started with FreePBX – Part 3 Making external calls

This article assumes you have completed part 1 and part 2 So we have configured our trunk and our extension and now we need to tell FreePBX to use that trunk when someone dials a number. This is done by creating an Outbound Route. The configuration below also takes in to consideration the fact that I am in the UK and that callcentric is a US company. Your setup may differ. Creating an outbound route First we need to click on “Outbound Routes” in the main menu on the left hand side of the screen

So we’ve got our trunk setup and now we need an extension so we can make a test call via the trunk. For testing I’m going to be using x-lite. A free sip softphone available for Windows and Linux from here. Adding an extension in FreePBX First we need to click on Extensions on the left hand main menu
