C# Class SIPSorcery.SIP.SIPDialogue

See "Chapter 12 Dialogs" in RFC3261.
The standard states that there are two independent CSeq's for a dialogue: one for requests from the UAC and for requests from the UAS. In practice it's been noted that is a UAS (initial UAS) sends an in-dialogue request with a CSeq less than the UAC's CSeq it can cause problems. To avoid this issue when generating requests the remote CSeq is always used.

Public Methods

Method Description
Hangup ( SIPTransport sipTransport, SIPEndPoint outboundProxy ) : void
SIPDialogue ( ) : System
SIPDialogue ( SIPRequest nonInviteRequest, string owner, string adminMemberId, string toTag ) : System

This constructor is used to create non-INVITE dialogues for example the dialogues used in SIP event interactions where the dialogue is created based on a SUBSCRIBE request.
SIPDialogue ( UACInviteTransaction uacInviteTransaction, string owner, string adminMemberId ) : System

This constructor is used by client user agents or SIP elements acting in a client user agent role. When acting as a client user agent the local fields are contained in the From header and the remote fields are in the To header.
SIPDialogue ( UASInviteTransaction uasInviteTransaction, string owner, string adminMemberId ) : System

This constructor is used by server user agents or SIP elements acting in a server user agent role. When acting as a server user agent the local fields are contained in the To header and the remote fields are in the From header.
SIPDialogue ( string callId, SIPRouteSet routeSet, SIPUserField localUser, SIPUserField remoteUser, int cseq, SIPURI remoteTarget, string localTag, string remoteTag, Guid cdrId, string owner, string adminMemberId, string sdp, string remoteSDP ) : System
