Your telephone

  • Sciences Po telephones now use ToIPSciences Po telephones now use ToIP

All Sciences Po telephones, on both the Paris and regional campuses, now use TOIP (telephony over internet protocol).


  • From your desktop telephone, dial 0 for an outside line.
  • To call an internal number, dial the last four digits. Example: to call 01 45 49 54 68 from your office telephone, dial only 54 68. 
  • To call a number on another campus using ToIP (Paris, Nancy, Le Havre), at the lowest rate possible, dial 6 + the department number + the last four digits of the person you wish to call. Example: 675 for Paris, 654 for Nancy, or 676 for Le Havre.
  • You can find staff telephone numbers in the Sciences Po directory (FR), accessible on the intranet.

You can also, if necessary or for priority service, call the switchboard: +33 (0)1 45 49 50 50.


First, determine the model number of your telephone, indicated on the upper right of the screen—7941, 7942, 7961 or 7962—in order to select the right tutorial.

Consult the instructions on the “ToIP” page of the Training in digital tools intranet (FR): user guide, contacts, directory calls, shortcuts, placing a call on hold, call forwarding, voicemail, out-of-office message, etc.
