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.
