Transfer and Callback
The PBX requires specifications for the transfer and the callback option for external callers to be executed as desired.
Proceed as follows for configuration:
•Configuring hook flash timing.
−Using the Configuration Manager (Subscriber (scr.) > Properties > Analogue settings)
•If necessary, switching the authorisation for external call transfer externally on.
−Using the Configuration Manager (Subscriber (scr.) > Properties > Authorisations)
•Configuring sufficient exchange line authorisations for the involved internal subscribers.
−Using the Configuration Manager (Subscriber (scr.) > Properties > Exchange line settings)
*Note: The transferring subscriber needs a sufficient exchange line authorisation for making external calls.
•Configuring the maximum duration of transferred calls (external to external).
−Using the Configuration Manager (Subscriber (scr.) > All subscribers)
•Switching the CCBS and CCNR option for external callers on.
−Using the Configuration Manager (Public switched tel. networks > ISDN > PBX base numbers/trunk bundles > Configure)
