Implements reliable SIP
provisional responses. SIP
is a request-response type
of protocol with two types
of responses: provisional
and final. Final responses
are sent reliably, using an
ACK to ensure receipt.
Provisional responses by
default are not sent reliably
and do not require an ACK;
however, in some cases,
such as for PSTN
interoperability support,
reliability of provisional
types of responses is
needed. Choose this option
to add the PRACK
(provisional ACK) message
support for reliability.
