[Phone Video SIP] How to send and catch custom params

[huy.nguyenthanh]

Hi,

I used createCall options "custom" and "sipHeaders" to make a call to another extension PBX (911).

But in websocket of 911 i can not found that params.

Any thing wrong?


Please help me how to send custom params.

Thanks.

Hello

You point to incoming notifications, such as ring and notifyIncomingCall

notifyIncomingCall - means you receive a call from another endpoint.
ring - means you receive progress status for the incoming call

Therefore you can't set params custom and sipHeaders for incoming calls.

These two parameters are applied for outgoing calls only.
So if you do createCall and pass parameters, this parameters should be visible in websocket message call
Please share JavaScript code how do you pass the parameters and which websocket frames were displayed.

Hi, thanks for reply

This is my code and websocket response from extension createCall

So in endpoint receive call, I can not get any custom params ?

 

[huy.nguyenthanh]

My case:
- Website customers register 1 extension createCall to another by flow PBX. Before createCall, customers must enter information such as name, email,...
- I want send this information to extension received call by custom params or sipHeaders, but websocket can not received.

sipHeaders are passed to PBX only, but not to other call party.
custom is passed in REST hook /call to a backend server. So you should set up your own backend to receive REST hooks and then send a custom data to a client by your own way. Please see the details about REST hooks here.

I see hook /call outgoing haven't parameter custom.

I see hook /call outgoing haven't parameter custom.

It supports custom option like any other direct invoke hook (publishStream. playStream etc). Please see this example, the custom parameters passing should also work for call:
1. Client side code:

    var outCall = session.createCall({
        callee: $("#callee").val(),
        visibleName: $("#sipLogin").val(),
        localVideoDisplay: localDisplay,
        remoteVideoDisplay: remoteDisplay,
        constraints: constraints,
        receiveAudio: true,
        receiveVideo: false,
        stripCodecs:"SILK",
        custom: {"token": "call123456"}
        ...
    });
    outCall.call();

2. The hook received by backend server looks like
