You are pretty much limited to measuring the delay and the jitter.<br>
The delay you can somewhat estimate prior to the call (with qualify for example).<br>
The jitter / packetloss you can only figure out when the call is already up for a while. (e.g. you might have no issues the first minute, but maybe packet loss will come in bursts after a minute).<div><div>

<div>A few years ago I spoke to a Finnish company that had a commercial solution for automated MOS estimation. So something exists though I have not tested it first-hand.<span class="HOEnZb"><font color="#888888"><br></font></span></div>

The voipmonitor guy is very handsome, maybe you can sponsor a patch to have the MOS calculation in real time. An external software can get it and halt the call if needed.</div>
