How can I make a call from my c# website to a phone?

We have a c# application built in .Net 4.5.2. We want to add a feature that lets the user click a phone number and be connected to that number through the browser. I have looked at both the WebRTC and the RingOut options and still have a few questions. Does RingOut need to work through the softphone? Can I log calls (start time, end time, comments, etc.) with both the RingOut and the WebRTC APIs? If I'm just calling out from the application will RingOut suffice?

If you choose to implement your own web phone from scratch using the WebRTC, you need to implement a lot.

Here is an alternative with the RingCentral Embeddable. Simply add the code below to your page (e.g. the Default.aspx)

<span><a href="#" onclick="makeCall('13129822345')">+13129822345</a></span>
<iframe width="300" height="500" id="rc-widget" allow="microphone" src="https://ringcentral.github.io/ringcentral-embeddable/app.html">
</iframe>
<script>
    function makeCall(number) {
        document.querySelector("#rc-widget").contentWindow.postMessage({
                type: 'rc-adapter-new-call',
                phoneNumber: number,
                toCall: true,
                }, '*');
    }
</script>

Thank you so much this works perfectly. I can still log calls done this way correct?

All calls are logged automatically by the system. All you need is to login your account and read the call-log

The RingCentral embeddable allows you do do much more than just making a call. E.g. you can implement event handlers to catch incoming call event and do inbound popup etc. Read the instructions from Github for details.

Hi I've been playing around with the demo you gave me and was wondering if there was a way to open the call in its own window. Ive tried using _blank and window.open but though they open the phone I'm having trouble getting the number to the phone and making the call. Is this something that is possible?

with the i-frame method when i put in my appkey it completely breaks.


                   

When I use the script method I get a notification on sign-in: You cannot use this device to make PSTN calls including Emergency Calls since no Digital Line is associated.

Then an Access Denied message

How do I connect a digital line to my app and also once that is done will multiple people be able to use this code to call at the same time?
