VoIP2FHEM or HOWTO control the FHEM with Asterisk

This is a HOWTO about the use of a VoIP-DECT-Telephone as a remote controller for the FHEM-Devices.
The provided scripts are under the GPL.

The Goal is
-- Switching the FS20-Devices
-- text2speach, the Telephone reads e.g. the measured-temp
-- Possibility to start scripts with the Remote Telephone
-- AND EVERYTHING MUST RUN ON THE NSLU2 :-)

On the NLSU2 (or every other Linux Box) runs an Asterisk. This machine must not be the machine with the FHEM. I bought the Voip-DECT-Telephone Siemens Gigaset C470 IP (80.-EUR). It has a nice Webinterface and it is possible to read in a self made telephone book.
The Asterisk calls depending on the dialed number a bash skript. After that Asterisk plays two soundfiles < text >< value > in a loop.

The NSLU2 is a weak machine. It always only creates a soundfile 1x and then stores it on the harddisk. A set of prebuild voices (e.g. digits from -20 to 90) are included. Some scripts for creating soundfiles and automatically the telephone book are provided too.

Go to http://fhem.dnsalias.net/voip2fhem and download the files.
-- Install with your package manager asterisk, sox, espeak. On the NLSU2: "apt-get install asterisk sox espeak".
-- Debian: activate asterisk in the /etc/default/asterisk
-- copy the scripts voip2fhem voip2fhem_create_telefonlist voip2fhem_create_txt2gsm to /usr/local/bin/ and be shure that they are executable (chmod +x /usr/local/bin/voip2fhem*)
-- extract the prepared voices "tar -xvzf voip2fhem_voices.tar.gz -C /" and give the correct rights "chown -R asterisk.asterisk /var/tmp/voip2fhem"
-- cp extensions.conf and sip.conf to /etc/asterisk/ and edit these files and the bash script /usr/local/bin/voip2fhem
-- restart/reload asterisk (/etc/init.d/asterisk restart or asterisk -r and then "extensions reload" and "sip reload")

-- if there isn't the required soundfile then the NSLU2 creates it. This needs minutes (example: the word "asterisk" needs 3 min). voip2fhem stores this file and the next time it will be used.
-- Use the script voip2fhem_create_txt2gsm on a faster machine to create the sounds. Usage: voip2fhem_create_txt2gsm "I love FHEM". The soundfile is then automatically copied to /var/tmp/voip2fhem/
-- it is also possible to connect the ASTERISK with the rest of the world (e.g. Sipgate, 1und1) :-)
-- for debug asterisk: "asterisk -r", "sip debug"
