10 Two stage dialing/callback serv-
er functionality
VoIPBox BRI Version 18.0.002 Page 227
This chapter describes money-saving features that expand
the functionality of your VoIPBox to include DTMF services
(two stage dialing) and callback capability. It is particularly
useful for companies with employees who travel often, be-
cause it eliminates expensive roaming fees.
In a two stage dialing scenario, the caller dials a number which
the VoIPBox connects with the integrated DTMF platform. He
then enters the destination number via DTMF. The VoIPBox
establishes the connection to the destination number.
Callback takes place, when the initial call is released and the
calling party is called back in a second call as a response.
Depending on your VoIPBox, various intelligent solutions as a
call server are possible. The most important scenarios and
properties are described here. The scenarios can also be com-
bined to suit your needs.

complete, the caller can press the # key. Otherwise, there is a
default timer set to 5 seconds, after which DTMF transmission
will automatically end.
