";t+=" Note: Implementation issues are outside the scope of this document, but the following tip is provided for avoiding race conditions of this type.  The caller can delay sending re-INVITE F6 for some period of time (2 seconds, perhaps), after which the caller can reasonably assume that its ACK has been received.  Implementors can decouple the actions of the user (e.g., pressing the hold button) from the actions of the protocol (the sending of re-INVITE F6), so that the UA can behave like this.  In this case, it is the implementor's choice as to how long to wait.  In most cases, such an implementation may be useful to prevent the type of race condition shown in this section. This document expresses no preference about whether or not they should wait for an ACK to be delivered.  After considering the impact on user experience, implementors should decide whether or not to wait for a while, because the user experience depends on the implementation and has no direct bearing on protocol behavior.",this.logger.warn(t)})();return}if(this.reinviteUserAgentServer){this.core.replyStateless(e,{statusCode:500,extraHeaders:t});return}if(this.reinviteUserAgentClient){this.core.replyStateless(e,{statusCode:491});return}}if(e.method===i.C.INVITE){let t=e.parseHeader("contact");if(!t)throw Error("Contact undefined.");if(!(t instanceof r.NameAddrHeader))throw Error("Contact not instance of NameAddrHeader.");this.dialogState.remoteTarget=t.uri}switch(e.method){case i.C.BYE:{let t=new f.ByeUserAgentServer(this,e);this.delegate&&this.delegate.onBye?this.delegate.onBye(t):t.accept(),this.dispose()}break;case i.C.INFO:{let t=new S.InfoUserAgentServer(this,e);this.delegate&&this.delegate.onInfo?this.delegate.onInfo(t):t.reject({statusCode:469,extraHeaders:["Recv-Info:"]})}break;case i.C.INVITE:{let t=new w.ReInviteUserAgentServer(this,e);this.signalingStateTransition(e),this.delegate&&this.delegate.onInvite?this.delegate.onInvite(t):t.reject({statusCode:488})}break;case i.C.MESSAGE:{let t=new T.MessageUserAgentServer(this.core,e);this.delegate&&this.delegate.onMessage?this.delegate.onMessage(t):t.accept()}break;case i.C.NOTIFY:{let t=new R.NotifyUserAgentServer(this,e);this.delegate&&this.delegate.onNotify?this.delegate.onNotify(t):t.accept()}break;case i.C.PRACK:{let t=new y.PrackUserAgentServer(this,e);this.delegate&&this.delegate.onPrack?this.delegate.onPrack(t):t.accept()}break;case i.C.REFER:{let t=new $.ReferUserAgentServer(this,e);this.delegate&&this.delegate.onRefer?this.delegate.onRefer(t):t.reject()}break;default:this.logger.log(`INVITE dialog ${this.id} received unimplemented ${e.method} request`),this.core.replyStateless(e,{statusCode:501})}}reliableSequenceGuard(e){let t=e.statusCode;if(!t)throw Error("Status code undefined");if(t>100&&t<200){let t=e.getHeader("require"),s=e.getHeader("rseq"),i=t&&t.includes("100rel")&&s?Number(s):void 0;if(i){if(this.rseq&&this.rseq+1!==i)return!1;this.rseq=this.rseq?this.rseq+1:i}}return!0}signalingStateRollback(){(this._signalingState===h.SignalingState.HaveLocalOffer||this.signalingState===h.SignalingState.HaveRemoteOffer)&&this._rollbackOffer&&this._rollbackAnswer&&(this._signalingState=h.SignalingState.Stable,this._offer=this._rollbackOffer,this._answer=this._rollbackAnswer)}signalingStateTransition(e){let t=(0,n.getBody)(e);if(t&&"session"===t.contentDisposition){if(this._signalingState===h.SignalingState.Stable&&(this._rollbackOffer=this._offer,this._rollbackAnswer=this._answer),e instanceof o.IncomingRequestMessage||e instanceof a.IncomingResponseMessage)switch(this._signalingState){case h.SignalingState.Initial:case h.SignalingState.Stable:this._signalingState=h.SignalingState.HaveRemoteOffer,this._offer=t,this._answer=void 0;break;case h.SignalingState.HaveLocalOffer:this._signalingState=h.SignalingState.Stable,this._answer=t;break;case h.SignalingState.HaveRemoteOffer:case h.SignalingState.Closed:break;default:throw Error("Unexpected signaling state.")}if(e instanceof c.OutgoingRequestMessage||(0,n.isBody)(e))switch(this._signalingState){case h.SignalingState.Initial:case h.SignalingState.Stable:this._signalingState=h.SignalingState.HaveLocalOffer,this._offer=t,this._answer=void 0;break;case h.SignalingState.HaveLocalOffer:break;case h.SignalingState.HaveRemoteOffer:this._signalingState=h.SignalingState.Stable,this._answer=t;break;case h.SignalingState.Closed:break;default:throw Error("Unexpected signaling state.")}}}start2xxRetransmissionTimer(){if(this.initialTransaction instanceof l.InviteServerTransaction){let e=this.initialTransaction,t=d.Timers.T1,s=()=>
