Bfv API and Associated Libraries
The Bfv Application Programming Interface (API) provides a set of
functions that enables applications programmers to write
telephony- or packet-network applications that run on Brooktrout’s
telecommunications boards or SR140 Fax software products. Using
the Bfv API, you can generate sophisticated, multichannel voice, fax,
and conferencing applications under Linux, Solaris, and Windows®
operating systems.
The Bfv API comprises several libraries that work together to give
flexibility in a variety of applications such as:
Voice processing (Dialogic® Brooktrout® TR1034 Fax Boards
only) and signal generation and detection
Fax
Connection to a variety of telephony interfaces:
T1 robbed bit
T1/E1 PRI
R2 CAS signaling
Analog
BRI
QSIG
IP
The libraries include:
Bfv API
Provides telephone line administration and initialization; board,
firmware, call control, and packet network configuration and
control; debugging and error handling, high-level call control for
analog, T1 robbed bit signaling, BRI, QSIG, and T1/E1 PRI; voice
play and record; signal generation and detection; fax
manipulation from high to low level; and file formatting for voice
and fax messages.
Boston Simple Message Interface (BSMI)
Provides very low-level call control for T1/E1 ISDN and
R2 signaling. The Bfv API uses the BSMI library to handle the
T1/E1 call control, but the higher-level call control functions
manage BSMI for you.
