[SOLVED] Passing CallerID for PSTN in From Header using JSSIP

Passing CallerID for PSTN in From Header using JSSIP

I'm using JsSIP to connect to FreeSwitch and then to the PSTN. I'm looking to pass the callerID in the From header. I have my code set up somewhat like this:

var TheCallerIDTest = '+33...number in E164 format';
var TheSipClient = new JsSIP.UA({....}); //works fine

var TheHandlers = {

    'sending': function (e) {

        var TheSipURI = new JsSIP.URI('sip', TheCallerIDTest, 'MyFreeswitchServerUrl', 5060, null, null);
        var TheHeader = new JsSIP.NameAddrHeader(TheSipURI, '', null);

        //displays the correct From header just fine
        console.log(TheHeader);

        //here's where I want to modify the INVITE request
        e.from = TheHeader; 
    },
}

var TheCallOptions = {

    'eventHandlers': TheHandlers,
    'mediaConstraints': { 'audio': true, 'video': false }
};

function TestCall() {

    TheSipClient.start();

    TheSipClient.call("+33...E164 number", TheCallOptions);
}

Looking at the documentation, https://jssip.net/documentation/3.3.x/api/session/#event_sending, I'm hoping the add a JsSIP.NameAddrHeader to the 'from' header of the JsSIP.OutgoingRequest INVITE request. The console output logs the correct From header I want to add.

However, when I look at the JsSIP:RTCSession emit "sending" [request:InitialOutgoingInviteRequest console log, it's not showing the header I want to add, and the From header that's received on the server is not the one I want to send.

What do I need to change in my code to make it work?

Solution

You need to do like this:

e.request.headers.From[0] = TheHeader;

Also probably this make sense to remove some other headers you do not want to send.
