I am using self developed CTI system and trying to integrate with softphone.

Currently I have integrated with AGEphone (https://www.ageet.com/home-en) however, the quality of the sound is pretty bad. The only reason why I am using AGEphone is it has protocol to hang up the call.

So I was wondering if there are any other softphone which has protocols to hang up from browser feature.

Doesn't matter if the software is free or paid. Any recommendation would be appreciated.

Using Windows' protocol handler mechanism, tSIP - http://tomeko.net/software/SIPclient/browser_integration.php (free):

<script type="text/javascript"> 
function hangup() {
    window.location = "tsip:HANGUP";
function call() {
    window.location = "tsip:" + document.getElementById("numberfield").value;   

or with direct link:

<a href="tsip:HANGUP">Hangup</a>
