I found bitree . ru Asterisk click2call a nice Chrome extension (call by click highlighted phone number in browser and display incoming calls).
Now this extension is no more available due to “lack of best practices” for Chrome extensions.
Is there any equivalent light and easy extension or eventually app to be installed ?
This might not be what you are looking for, but I would recommend the Xtelsio CTI Client It has just about every option you could want, including click to dial. It does take just a little bit of work to set it up, though.
Do you have a physical phone on your extension? That will make it easier to setup.
what about this one ? I had use this Clic2Call php before.
