Making Call Transfers Using QSIG
November 2009 186
Name Identification
This feature allows the Bfv API to see the text name of the user
similar to Caller ID on an analog phone line. Therefore, if the
network provides the calling party, the calling party’s name is
reported through BfvLineWaitForCall/BfvCallWaitForSetup
functions located in the res.calling_party_subaddress field of the
args structures.
Table 7 lists the Bfv APIs that are associated with QSIG and are
documented in detail in Volume 2, Bfv-Level Call Control and Call
Switching, Bfv Reference Manual.
* Supported only on the QSIG protocol.
For detailed information concerning the Bfv API QSIG call control
configuration functions and data structures, see Volume 2, Bfv-Level
Call Control and Call Switching, Bfv Reference Manual.
