Figure 19. SIP Configuration Model
With dual-purpose modules in place, end-users can choose between
PSTN or IP mode. Your applications can determine whether the
module supports the IP or PSTN mode either at runtime or
installation.
Adding IP Call Control using the Bfv API
Because the Dialogic® Brooktrout® Bfv API uniformly supports a
wide set of transports including IP, you can use the same
applications to manage calls over IP as when using the PSTN.You
can configure IP call control using the Dialogic® Brooktrout®
Configuration Tool (a GUI product) or by setting values in call
control configuration files.
