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 + // responses. + // + // https://tools.ietf.org/html/rfc3262#section-5 + //// + // The Offer/Answer Model Implementation + // + // The offer/answer model is straight forward, but one MUST READ the specifications... + // + // 13.2.1 Creating the Initial INVITE (paragraph 8 in particular) + // https://tools.ietf.org/html/rfc3261#section-13.2.1 + // + // 5 The Offer/Answer Model and PRACK + // https://tools.ietf.org/html/rfc3262#section-5 + // + // Session Initiation Protocol (SIP) Usage of the Offer/Answer Model + // https://tools.ietf.org/html/rfc6337 + // + // *** IMPORTANT IMPLEMENTATION CHOICES *** + // + // TLDR... + // + // 1) Only one offer/answer exchange permitted during initial INVITE. + // 2) No "early media" if the initial offer is in an INVITE. + // + // + // 1) Initial Offer/Answer Restriction. + // + // 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.

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. + //// + //// + // ROADMAP: The Offer/Answer Model Implementation + // + // The "no early media if offer in INVITE" implementation is not a + // welcome one. The masses want it. The want it and they want it + // to work for WebRTC (so they want to have their cake and eat too). + // + // So while we currently cannot make the offer in INVITE+forking+webrtc + // case work, we decided to do the following... + // + // 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.

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. + //// + //// + // ROADMAP: The Offer/Answer Model Implementation + // + // The "no early media if offer in INVITE" implementation is not a + // welcome one. The masses want it.

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.
