Examples of javax.sip.Dialog.createAck()

javax.sip.Dialog.createAck()
Creates an ACK request for an Invite that was responded with 2xx response. The cseq number for the invite is supplied to relate the ACK to its original invite request. @param cseq -the CSeq number to be placed in the ACK request. @return The newly created ACK request message. @throws InvalidArgumentException if there is a problem with the supplied cseq ( for example <= 0 ). @throws SipException if the cseq does not relate to a previously sent INVITE or if the Method that created the Dialog is not an INVITE ( for example SUBSCRIBE) @since 1.2
