No I'm afraid you can't. Our Click2Call extension in Chrome will open the 3CX App only. The best you can do is select what application opens TEL links that Windows identifies. For that, you can navigate to your Windows Search and type "Default Apps", scroll to the bottom and select "Choose default apps by protocol" and then scroll down to TEL and select which app to open TEL links with.
we'd save so much time with a feature like this. I wish i knew how to code sometimes as i'd give it a go to try and make a solution. Thanks for the reply
