1. Making calls with the assistance of the automatic operator

Call 6666 and say the name of the person you want to be connected to (internal calls). The automatic operator will repeat the name, if it is incorrect say NEJ [no], if it is correct, wait to be connected. Do not speak too slowly, but try to speak clearly. 


2. Redirect your telephone

Redirection is only active for the landline number (013). Calls to the mobile number will go through.

Redirections made via a telephone apply from the time they were entered. Absence can be reported to the switchboard in advance - call 1000 (013-28 10 00). The operator enters the absence in the redirection computer, which will redirect the connection at the relevant point in time. 

There are three ways to redirect your telephone.

  1. Via keypad.
  2. Via automatic operator.
  3. Via switchboard.
