Automatic redial/call back on busy 

If the person you are trying to call is constantly engaged your telephone can take 
over by repeatedly trying to call the other person. For automatic redialling the 
dialling is repeated 10 times every 15 seconds. With the "Call back on busy" 
function a call is signalled to you as soon as the person you are trying to reach is 
available. Your telephone network or extension system must support this function 
(refer also to your network operator and PABX manufacturer user instructions). To 
activate "Call back on busy" you usually dial a certain combination of digits (e.g. 
Hookflash *37#). The combination of digits must be pre-entered as described in 
"Settings/Telephone/Call back code". 

 

 

You call someone via the 
speakerphone (without lifting the 
receiver); the number is busy. 

"Subscriber busy" is displayed. 

 

 

 

 

 

 

Select the required function using 
the cursor keys (up/down). 

“Call back” or “Redial” is shown 
inversely. 

 

Press OK. 

For redialling the call is repeated up to 10 
times. 
For call back this is indicated as soon as 
the called subscriber hangs up.
