Installing Sangoma cards with Asterisk and Dahdi on Debian Wheezy

My preferred method for installing Asterisk on Debian is by using standard Debian packages. I don’t want the hassle of re-compiling packages whenever there is an updated version or some security hole gets closed.

Step one is getting Asterisk & Dahdi installed and working.

Do this:

apt-get install asterisk libpri1.4 asterisk-dahdi

The country code for the UK is 44.

Now to get the dahdi kernel modules built, install dahdi-source and use module assistant to install the modules:

apt-get install dahdi-source

m-a a-i dahdi

Now you should have Asterisk & Dahdi installed.

Before installing the Sangoma Wanpipe drivers, you need to compile the Dahdi source (module assistant just compiles the kernel module parts):

cd /usr/src/modules/dahdi

make

The rest is the same as the standard installation instructions for Wanpipe which are here (scroll down to Sangoma Driver Installation):

http://wiki.sangoma.com/wanpipe-linux-asterisk-dahdi

In summary:

apt-get install automake autoconf libtool libncurses5-dev bison libxml2-dev cmake flex

wget ftp://ftp.sangoma.com/linux/current_wanpipe/wanpipe-current.tgz

tar xzf wanpipe-current.tgz

cd wanpipe-{version}/

./Setup install

and just follow the instructions.

How to: 2N Door Entry and Cisco UC540

One of our customers recently had a problem with an analogue version of the 2N Helios Force door entry unit that they had connected up to a Cisco UC540 system.

Calls were initiated with no problems but the system was not sending disconnect tones to the door entry unit, meaning that the call wasn’t ended until the button was pressed for a second time.

The solution ended up being quite simple! You need to change the analogue port settings in the UC540 to a managed user extension rather than a standard analogue port. The system should now disconnect the call properly when the call is hung up.
