We recently tested the Siemens A580 IP on a Asterisk server.
Works like a charm with excellent sound quality and reach!

The base station is easy to configure via browser.
Can recommend this device if you need reliable wireless phone connection in your office or factory. DECT to IP is still far better than Wi-Fi phones (at least in my experience :-)

The phone:

The nice and clean configuration website:

A client request us to create a H323 trunk between Asterisk and their existing "legacy" PBX.

It took as a while to figure things out and i thought i share (and spare you the painful try and error time) this.

I assume you have the build-essentials installed before you start this "exercise":.
I also recommend that you do this steps before you install dahdi, libpri asterisk etc...
Make sure you don't use any distro related H323 packages!

First you need to make sure you have flex installed:
apt-get install flex

Then you need to install "pwlib":

cd /usr/src
wget http://downloads.sourceforge.net/openh323/pwlib-v1_10_3-src-tar.gz
tar zxvf pwlib-v1_10_3-src-tar.gz
cd pwlib_v1_10_3/
./configure
make

Attention: Ignore all the warnings!!!

export PWLIBDIR=/usr/src/pwlib_v1_10_3
cp $PWLIBDIR/lib/libpt_linux_x86_r.so.1.10.3 /usr/lib
cd ..

After this you install openH323:

cd /usr/src
wget http://downloads.sourceforge.net/openh323/openh323-v1_18_0-src-tar.gz
tar zxvf openh323-v1_18_0-src-tar.gz
cd openh323_v1_18_0/
./configure --disable-ixj
make opt

Attention: Ignore all the warnings!!!

export OPENH323DIR=/usr/src/openh323_v1_18_0
cp $OPENH323DIR/lib/libh323_linux_x86_r.so.1.18.0 /usr/lib
cd ..

After this you normally install Dahdi, libpri, asterisk etc etc.

When you ./configure asterisk you will see that Asterisk detects your H323:

If you do a make menuselect you will see that chan_h323 is marked for installation:

Enjoy your H323 with Asterisk!!!!

Good Morning

Asterisk latest 1.4.x and 1.6.x will not start if
you configure TDMoE without having a FoneBridge connected.
You will get a "Zaptel / Dahdi configuration" error.

The older versions of Asterisk could start without timing device (even without ztdummy or dahdi_dummy)

Therefore make sure that you have your Redfone FoneBridge connected to your system
before you start Asterisk. :-)

With best regards
Daniel

Good Morning

Yesterday, Frank and myself delivered and installed the first Asterisk server in one of the over 20 factories of Top Glove.

We are very happy and thankful that Top Glove is starting to use Asterisk :-)

Right in front of the factory we had to "fight" our ways through "wild" malaysian cows... :-)

Cheers and enjoy the week!

Daniel

Thanks a lot to all the great organizers!!!
Outstanding job.

I enjoyed the speech :-)
