  1. ****** VoIP2FHEM or HOWTO control the FHEM with Asterisk ******
    2. 

  2. 

  3. Description
    4. 

  4.     * This is a HOWTO about the use of a VoIP-DECT-Telephone as a remote
    5. 

  5.       controller for the FHEM-Devices.
    6. 

  6.       The provided scripts are under the GPL.
    7. 

  7. 

  8.       The Goal is
    9. 

  9.       -- Switching the FS20-Devices
    10. 

  10.       -- text2speach, the Telephone reads e.g. the measured-temp
    11. 

  11.       -- Possibility to start scripts with the Remote Telephone
    12. 

  12.       -- AND EVERYTHING MUST RUN ON THE NSLU2 :-)
    13. 

  13. 

  14. Technical Overview
    15. 

  15.     * On the NLSU2 (or every other Linux Box) runs an Asterisk. This machine
    16. 

  16.       must not be the machine with the FHEM. I bought the Voip-DECT-Telephone
    17. 

  17.       Siemens Gigaset C470 IP (80.-EUR). It has a nice Webinterface and it is
    18. 

  18.       possible to read in a self made telephone book.
    19. 

  19.       The Asterisk calls depending on the dialed number a bash skript. After
    20. 

  20.       that Asterisk plays two soundfiles < text >< value > in a loop.
    21. 

  21. 

  22.       The NSLU2 is a weak machine. It always only creates a soundfile 1x and
    23. 

  23.       then stores it on the harddisk. A set of prebuild voices (e.g. digits
    24. 

  24.       from -20 to 90) are included. Some scripts for creating soundfiles and
    25. 

  25.       automatically the telephone book are provided too.
    26. 

  26. Installation
    27. 

  27.     * Go to http://fhem.dnsalias.net/voip2fhem and download the files.
    28. 

  28.       -- Install with your package manager asterisk, sox, espeak. On the NLSU2:
    29. 

  29.       "apt-get install asterisk sox espeak".
    30. 

  30.       -- Debian: activate asterisk in the /etc/default/asterisk
    31. 

  31.       -- copy the scripts voip2fhem voip2fhem_create_telefonlist
    32. 

  32.       voip2fhem_create_txt2gsm to /usr/local/bin/ and be shure that they are
    33. 

  33.       executable (chmod +x /usr/local/bin/voip2fhem*)
    34. 

  34.       -- You can find on http://fhem.dnsalias.net/voip2fhem prepared voices:
    35. 

  35.       "tar -xvzf voip2fhem_voices.tar.gz -C /" and give the correct rights
    36. 

  36.       "chown -R asterisk.asterisk /var/tmp/voip2fhem"
    37. 

  37.       -- cp extensions.conf and sip.conf to /etc/asterisk/ and edit these files
    38. 

  38.       and the bash script /usr/local/bin/voip2fhem
    39. 

  39.       -- restart/reload asterisk (/etc/init.d/asterisk restart or asterisk -
    40. 

  40.       r and then "extensions reload" and "sip reload")
    41. 

  41. Hints
    42. 

  42.     * -- if there isn't the required soundfile then the NSLU2 creates it. This
    43. 

  43.       needs minutes (example: the word "asterisk" needs 3 min). voip2fhem
    44. 

  44.       stores this file and the next time it will be used.
    45. 

  45.       -- Use the script voip2fhem_create_txt2gsm on a faster machine to create
    46. 

  46.       the sounds. Usage: voip2fhem_create_txt2gsm "I love FHEM". The soundfile
    47. 

  47.       is then automatically copied to /var/tmp/voip2fhem/
    48. 

  48.       -- it is also possible to connect the ASTERISK with the rest of the world
    49. 

  49.       (e.g. Sipgate, 1und1) :-)
    50. 

  50.       -- for debug asterisk: "asterisk -r", "sip debug"
    51.

  53. Have fun and success :-)
