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 (page Subscriber (scr.) > Properties > Analogue settings)

• If necessary, switching the authorisation for external call transfer externally on.

-Using the Configuration Manager (page Subscriber (scr.) > Properties > Authorisations)

• Configuring sufficient exchange line authorisations for the involved internal subscribers.

-Using the Configuration Manager (page 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 (page Subscriber (scr.) > All subscribers)

• Switching the CCBS and CCNR option for external callers on.

-Using the Configuration Manager (page Public switched tel. networks > ISDN > PBX base numbers/trunk bundles > Configure)
