You are pretty much limited to measuring the delay and the jitter.
The delay you can somewhat estimate prior to the call (with qualify for 
example).
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).
