[Ekiga-list] python dbus script - pcspeaker

["Fredrik Axelsson" <fraxbe gmail com>]

Hi All!

I hacked up a little script which employs the pcspeaker as a ring device for ekiga. If someone has already posted something similar before I apologize.

For the script to work; 
Ekiga needs to be compiled with dbus support

Depending on your distro you will need packages that provide:
  - beep (a program which beeps the pcspeaker)
  - python-dbus bindings  (on gentoo they are included with dbus...I think)
  - pygtk 

If you are using Linux, you will need a kernel compiled with
 - CONFIG_INPUT_PCSPKR 

Note that beep might need to be set suid root to work when it's not used from a terminal. Look at the beep man-page for more information. 

Put the script in one of your session startup scripts. On my machine I have selected the script to be started along with gnome
in the control-center dialog. It does not matter whether the script is launched before or after ekiga. A dbus session must exist though. 

The script can be extended in many ways, for example i use the python dcop extension to pause amarok when ekiga is ringing and a call is connected.

Hope someone else will find this useful.
