Examples with Authorization gov.nist.javax.sip.header.Authorization used on opensource projects

Example 1 with Authorization

use of gov.nist.javax.sip.header.Authorization in project XobotOS by xamarin.

the class SIPDialog method createAck.

/*
     * (non-Javadoc) The UAC core MUST generate an ACK request for each 2xx received from the
     * transaction layer. The header fields of the ACK are constructed in the same way as for any
     * request sent within a dialog (see Section 12) with the exception of the CSeq and the header
     * fields related to authentication. The sequence number of the CSeq header field MUST be the
     * same as the INVITE being acknowledged, but the CSeq method MUST be ACK. The ACK MUST
     * contain the same credentials as the INVITE. If the 2xx contains an offer (based on the
     * rules above), the ACK MUST carry an answer in its body. If the offer in the 2xx response is
     * not acceptable, the UAC core MUST generate a valid answer in the ACK and then send a BYE
     * immediately.
     * 
     * Note that for the case of forked requests, you can create multiple outgoing invites each
     * with a different cseq and hence you need to supply the invite.
     * 
     * @see javax.sip.Dialog#createAck(long)
