/**
|
|
* Terminating a Session
|
|
*
|
|
* This section describes the procedures for terminating a session
|
|
* established by SIP. The state of the session and the state of the
|
|
* dialog are very closely related. When a session is initiated with an
|
|
* INVITE, each 1xx or 2xx response from a distinct UAS creates a
|
|
* dialog, and if that response completes the offer/answer exchange, it
|
|
* also creates a session. As a result, each session is "associated"
|
|
* with a single dialog - the one which resulted in its creation. If an
|
|
* initial INVITE generates a non-2xx final response, that terminates
|
|
* all sessions (if any) and all dialogs (if any) that were created
|
|
* through responses to the request. By virtue of completing the
|
|
* transaction, a non-2xx final response also prevents further sessions
|
|
* from being created as a result of the INVITE. The BYE request is
|
|
* used to terminate a specific session or attempted session. In this
|
|
* case, the specific session is the one with the peer UA on the other
|
|
* side of the dialog. When a BYE is received on a dialog, any session
|
|
* associated with that dialog SHOULD terminate. A UA MUST NOT send a
|
|
* BYE outside of a dialog. The caller's UA MAY send a BYE for either
|
|
* confirmed or early dialogs, and the callee's UA MAY send a BYE on
|
|
* confirmed dialogs, but MUST NOT send a BYE on early dialogs.
|
|
*
|
|
* However, the callee's UA MUST NOT send a BYE on a confirmed dialog
|
|
* until it has received an ACK for its 2xx response or until the server
|
|
* transaction times out. If no SIP extensions have defined other
|
|
* application layer states associated with the dialog, the BYE also
|
|
* terminates the dialog.
|
|
*

* https://tools.ietf.org/html/rfc3261#section-15

* This document describes an extension to the Session Initiation

|
|
* Note that the event notification mechanisms defined herein are NOT

|
* event subscription and notification.
|
|
*
|
|
* This document represents a backwards-compatible improvement on the
|
|
* original mechanism described by RFC 3265, taking into account several
|
|
* years of implementation experience. Accordingly, this document
|
|
* obsoletes RFC 3265. This document also updates RFC 4660 slightly to
|
|
* accommodate some small changes to the mechanism that were discussed

|
* indication that a phone is ringing). This is accomplished with a
|

* responses establish early dialogs and therefore follow the procedures

* of Section 12.1.1 in addition to those of Section 8.2.6. A UAS MAY
|
|
* send as many provisional responses as it likes. Each of these MUST
|
|
* indicate the same dialog ID. However, these will not be delivered

|
* reliably.
|
|
*
|
|
* If the UAS desires an extended period of time to answer the INVITE,

* it will need to ask for an "extension" in order to prevent proxies
|
|
* from canceling the transaction. A proxy has the option of canceling
|
|
* a transaction when there is a gap of 3 minutes between responses in a

* transaction. To prevent cancellation, the UAS MUST send a non-100

* provisional response at every minute, to handle the possibility of

/**
|
|
* Sends the INVITE request.
|
|
*
|
|
* @remarks
|
|
* TLDR...
|
|
* 1) Only one offer/answer exchange permitted during initial INVITE.
|
|
* 2) No "early media" if the initial offer is in an INVITE (default behavior).
|
|
* 3) If "early media" and the initial offer is in an INVITE, no INVITE forking.
|
|
*
|
|
* 1) Only one offer/answer exchange permitted during initial INVITE.
|
|
*
|
|
* Our implementation replaces the following bullet point...
|
|
*
|
|
* o After having sent or received an answer to the first offer, the
|
|
* UAC MAY generate subsequent offers in requests based on rules
|
|
* specified for that method, but only if it has received answers
|
|
* to any previous offers, and has not sent any offers to which it
|
|
* hasn't gotten an answer.
|
|
* https://tools.ietf.org/html/rfc3261#section-13.2.1
|
|
*
|
|
* ...with...
|
|
*
|
|
* o After having sent or received an answer to the first offer, the
|
|
* UAC MUST NOT generate subsequent offers in requests based on rules
|
|
* specified for that method.
|
|
*
|
|
* ...which in combination with this bullet point...
|
|
*
|
|
* o Once the UAS has sent or received an answer to the initial
|
|
* offer, it MUST NOT generate subsequent offers in any responses
|
|
* to the initial INVITE. This means that a UAS based on this
|
|
* specification alone can never generate subsequent offers until
|
|
* completion of the initial transaction.
|
|
* https://tools.ietf.org/html/rfc3261#section-13.2.1
|
|
*
|
|
* ...ensures that EXACTLY ONE offer/answer exchange will occur
|
|
* during an initial out of dialog INVITE request made by our UAC.
|
|
*
|
|
*
|
|
* 2) No "early media" if the initial offer is in an INVITE (default behavior).
|
|
*
|
|
* While our implementation adheres to the following bullet point...
|
|
*
|
|
* o If the initial offer is in an INVITE, the answer MUST be in a
|
|
* reliable non-failure message from UAS back to UAC which is
|
|
* correlated to that INVITE. For this specification, that is
|
|
* only the final 2xx response to that INVITE. That same exact
|
|
* answer MAY also be placed in any provisional responses sent
|
|
* prior to the answer. The UAC MUST treat the first session
|
|
* description it receives as the answer, and MUST ignore any
|
|
* session descriptions in subsequent responses to the initial
|
|
* INVITE.
|
|
* https://tools.ietf.org/html/rfc3261#section-13.2.1
|
|
*
|
|
* We have made the following implementation decision with regard to early media...
|
|
*
|
|
* o If the initial offer is in the INVITE, the answer from the
|
|
* UAS back to the UAC will establish a media session only
|
|
* only after the final 2xx response to that INVITE is received.
|
|
*
|
|
* The reason for this decision is rooted in a restriction currently
|
|
* inherent in WebRTC. Specifically, while a SIP INVITE request with an
|
|
* initial offer may fork resulting in more than one provisional answer,
|
|
* there is currently no easy/good way to to "fork" an offer generated
|
|
* by a peer connection. In particular, a WebRTC offer currently may only
|
|
* be matched with one answer and we have no good way to know which
|
|
* "provisional answer" is going to be the "final answer". So we have
|
|
* decided to punt and not create any "early media" sessions in this case.
|
|
*
|
|
* The upshot is that if you want "early media", you must not put the
|
|
* initial offer in the INVITE. Instead, force the UAS to provide the
|
|
* initial offer by sending an INVITE without an offer. In the WebRTC
|
|
* case this allows us to create a unique peer connection with a unique
|
|
* answer for every provisional offer with "early media" on all of them.
|
|
*
|
|
*
|
|
* 3) If "early media" and the initial offer is in an INVITE, no INVITE forking.
|
|
*
|
|
* The default behavior may be altered and "early media" utilized if the
|
|
* initial offer is in the an INVITE by setting the `earlyMedia` options.
|
|
* However in that case the INVITE request MUST NOT fork. This allows for
|
|
* "early media" in environments where the forking behavior of the SIP
|
|
* servers being utilized is configured to disallow forking.

/**
|
|
* 13.2.1 Creating the Initial INVITE
|
|
*
|
|
* Since the initial INVITE represents a request outside of a dialog,
|
|
* its construction follows the procedures of Section 8.1.1. Additional
|
|
* processing is required for the specific case of INVITE.
|
|
*
|
|
* An Allow header field (Section 20.5) SHOULD be present in the INVITE.
|
|
* It indicates what methods can be invoked within a dialog, on the UA
|
|
* sending the INVITE, for the duration of the dialog. For example, a
|
|
* UA capable of receiving INFO requests within a dialog [34] SHOULD
|
|
* include an Allow header field listing the INFO method.
|
|
*
|
|
* A Supported header field (Section 20.37) SHOULD be present in the
|
|
* INVITE. It enumerates all the extensions understood by the UAC.
|
|
*
|
|
* An Accept (Section 20.1) header field MAY be present in the INVITE.
|
|
* It indicates which Content-Types are acceptable to the UA, in both
|
|
* the response received by it, and in any subsequent requests sent to
|
|
* it within dialogs established by the INVITE. The Accept header field
|
|
* is especially useful for indicating support of various session
|
|
* description formats.
|
|
*
|
|
* The UAC MAY add an Expires header field (Section 20.19) to limit the
|
|
* validity of the invitation. If the time indicated in the Expires
|
|
* header field is reached and no final answer for the INVITE has been
|
|
* received, the UAC core SHOULD generate a CANCEL request for the
|
|
* INVITE, as per Section 9.
|
|
*
|
|
* A UAC MAY also find it useful to add, among others, Subject (Section
|
|
* 20.36), Organization (Section 20.25) and User-Agent (Section 20.41)
|
|
* header fields. They all contain information related to the INVITE.
|
|
*
|
|
* The UAC MAY choose to add a message body to the INVITE. Section
|
|
* 8.1.1.10 deals with how to construct the header fields -- Content-
|
|
* Type among others -- needed to describe the message body.

|
|
// of the session. The offer indicates the desired communications means
|
|
// (audio, video, games), parameters of those means (such as codec

|
// media from the offerer. An offer/answer exchange is within the
|
|
// context of a dialog, so that if a SIP INVITE results in multiple
|
|
// dialogs, each is a separate offer/answer exchange. The offer/answer
|
|
// model defines restrictions on when offers and answers can be made

|
|
// in the first reliable non-failure message from the UAS back to
|
|
// the UAC. In this specification, that is the final 2xx
|
|
// response.
|
|
//
|
|
// o If the initial offer is in an INVITE, the answer MUST be in a

|
// reliable non-failure message from UAS back to UAC which is
|
|
// correlated to that INVITE. For this specification, that is

|
// description it receives as the answer, and MUST ignore any

// session descriptions in subsequent responses to the initial
|
|
// INVITE.
|
|
//
|
|
// o If the initial offer is in the first reliable non-failure
|
|
// message from the UAS back to UAC, the answer MUST be in the
|
|
// acknowledgement for that message (in this specification, ACK
|
|
// for a 2xx response).
|
|
//
|
|
// o After having sent or received an answer to the first offer, the
|
|
// UAC MAY generate subsequent offers in requests based on rules
|

|
// to any previous offers, and has not sent any offers to which it

|
//
|
|

|
|
// 5 The Offer/Answer Model and PRACK
|
|
//
|
|
// RFC 3261 describes guidelines for the sets of messages in which
|
|
// offers and answers [3] can appear. Based on those guidelines, this
|
|
// extension provides additional opportunities for offer/answer
|
|
// exchanges.
|
|
// If the INVITE contained an offer, the UAS MAY generate an answer in a
|
|
// reliable provisional response (assuming these are supported by the
|
|
// UAC). That results in the establishment of the session before
|
|
// completion of the call. Similarly, if a reliable provisional
|
|
// response is the first reliable message sent back to the UAC, and the
|
|
// INVITE did not contain an offer, one MUST appear in that reliable
|
|
// provisional response.
|
|
// If the UAC receives a reliable provisional response with an offer
|
|
// (this would occur if the UAC sent an INVITE without an offer, in
|
|
// which case the first reliable provisional response will contain the
|
|
// offer), it MUST generate an answer in the PRACK. If the UAC receives
|
|
// a reliable provisional response with an answer, it MAY generate an
|
|
// additional offer in the PRACK. If the UAS receives a PRACK with an
|
|
// offer, it MUST place the answer in the 2xx to the PRACK.
|
|
// Once an answer has been sent or received, the UA SHOULD establish the
|
|
// session based on the parameters of the offer and answer, even if the
|
|
// original INVITE itself has not been responded to.
|
|
// If the UAS had placed a session description in any reliable
|
|
// provisional response that is unacknowledged when the INVITE is
|
|
// accepted, the UAS MUST delay sending the 2xx until the provisional
|
|
// response is acknowledged. Otherwise, the reliability of the 1xx
|
|
// cannot be guaranteed, and reliability is needed for proper operation
|
|
// of the offer/answer exchange.
|
|
// All user agents that support this extension MUST support all
|
|
// offer/answer exchanges that are possible based on the rules in
|
|
// Section 13.2 of RFC 3261, based on the existence of INVITE and PRACK
|
|
// as requests, and 2xx and reliable 1xx as non-failure reliable

|

// Currently if `earlyMedia` is enabled and the INVITE request forks,

// the session is terminated if the early dialog does not match the
|
|
// confirmed dialog. This restriction make sense in a WebRTC environment,

|
// but there are other environments where this restriction does not hold.
|
|
//
|
|
// So while we currently cannot make the offer in INVITE+forking+webrtc
|
|
// case work, we propose doing the following...
|
|
//
|
|
// OPTION 1
|
|
// - add a `earlyMediaForking` option and
|
|
// - require SDH.setDescription() to be callable multiple times.
|
|
//
|
|
// OPTION 2
|
|
// 1) modify SDH Factory to provide an initial offer without giving us the SDH, and then...
|
|
// 2) stick that offer in the initial INVITE, and when 183 with initial answer is received...
|
|
// 3) ask SDH Factory if it supports "earlyRemoteAnswer"
|
|
// a) if true, ask SDH Factory to createSDH(localOffer).then((sdh) => sdh.setDescription(remoteAnswer)
|
|
// b) if false, defer getting a SDH until 2xx response is received
|
|
//
|
|
// Our supplied WebRTC SDH will default to behavior 3b which works in forking environment (without)
|
|
// early media if initial offer is in the INVITE). We will, however, provide an "inviteWillNotFork"
|
|
// option which if set to "true" will have our supplied WebRTC SDH behave in the 3a manner.
|
|
// That will result in
|
|
// - early media working with initial offer in the INVITE, and...
|
|
// - if the INVITE forks, the session terminating with an ERROR that reads like
|
|
// "You set 'inviteWillNotFork' to true but the INVITE forked. You can't eat your cake, and have it too."
|
|
// - furthermore, we accept that users will report that error to us as "bug" regardless

|
|
* case is to dispose of `Registerer` when unregistered and create a new
