The new parameter IDs are added for the existing IPSET_CONFIG set ID as shown in the
following table.
By default, SIP re-INVITE messages upon media switch are sent automatically. The user
application has to specifically disable the transmission of the re-INVITE by using the
IPSET_CONFIG parameters. Typically, the automatic re-INVITE messages would be
disabled on one side user application only, namely a fax server type of application that
receives faxes.
The user application has to know whether to use this functionality depending on how the
application is to be used. This is usually done at the start of an application. If the
automatic re-INVITE messages are disabled on two applications in a back-to-back test,
the switch from fax to audio will never occur, because neither side will send out a re-
INVITE message to the other to renegotiate new media (audio) when a fax session ends.
The automatic re-INVITE messages can be disabled/enabled on a board, line, or call
reference number (CRN) device basis. Code examples are shown below.
