How to get SIP.JS Session from Inviter

[Michael Sila]

So I'm following the guide and I have the following code:

try {

const inviter = new Inviter(this.userAgentSip, target);

inviter.stateChange.addListener((state: SessionState) => {

console.log(`Session state changed to ${state}`);

switch (state) {

case SessionState.Initial:

break;

case SessionState.Establishing:

break;

case SessionState.Established:

this.setupRemoteMedia(inviter);

break;

case SessionState.Terminating:

// fall through

case SessionState.Terminated:

this.cleanupRemoteMedia();

this.sipSession = null

break;

default:

throw new Error("Unknown session state.");

}

});

inviter.invite().then((info) => {

info.delegate.onAccept = (response ) => {

console.log("Got Session");

this.sipSession = response.session as any ;

this.inviting = false;

}

}).catch(error => {

console.error(error)

this.inviting = false;

this.sipSession = null;

})

} catch(err) {

this.inviting = false;

console.error(err)

}

I was trying to set the session by getting it from the OnAccept Callback. However, the session from that response seems to be fundamentally different than the session object referenced in the guides. Specifically, it is missing several methods and the state object. The guide https://sipjs.com/guides/end-call/ frustratingly skips over how to grab the session. Here's the make call for comparison: https://sipjs.com/guides/make-call/ . There's no description of how to actually grab the session object.

This might help you..

case SessionState.Established:
let sessionDescriptionHandler: SessionDescriptionHandler = inviter.sessionDescriptionHandler as SessionDescriptionHandler;
setupRemoteMedia(sessionDescriptionHandler);

break;

Thank you. I think I figured it out; You can get the session from the inviter object itself.

which method did you use? I am also working with sessions.. Just wanted to know various ways to get a session.

The inviter object is actually just an instance of a session. When you create an inviter, store it in a non locally scoped variable and then call stuff on it as needed.
