I have installed in a partner dev. edition the Open CTI (This org has namespace) the Open CTI package. I have made the configuration and added in the CTI Adapter URL the link: https://MYDOMAIN-dev-ed.my.salesforce.com/apex/NAMESPACE__demoAdapterPage. However when opening the phone it is displaying a blank page and i get an error in the console: iframeinterface.js:1 Uncaught DOMException: Blocked a frame with origin "https://cgnrulesets-dev-ed.my.salesforce.com" from accessing a cross-origin frame. at Object.handleOnload (https://cgnrulesets-dev-ed.my.salesforce.com/support/console/xdomain/30.0/iframeinterface.js:1:357) at window.onload (https://cgnrulesets-dev-ed.my.salesforce.com/support/console/xdomain/30.0/crossDomainProxy.html:4:89)

Any ideas? Is open cti supported in this edition? I have tried lots of things like putting the whole url or just /apex/demoAdapterPage, but haven't found solution yet.

I was able to fix it by changing the reference for lightning component in the Visualforce page demoAdapterPage from c:lightningComponentName to YOUR_NAMESPACE:lightningComponentName

<script type="text/javascript">

        $Lightning.use("YOUR_NAMESPACE:demoAdapterOut", function() {
            function(cmp) {
                    callback: function() {
                        console.log('CLICK TO DIAL ENABLED');
