Re: user still hears ringback while the other end already picked
Start with defining (and drawing all components) the incoming call flow. Is the call coming into THIS gateway or across the WAN? Where is the CallManager, LAN switches, IP phone that answered the call with respect to the call flow drawing?
What number called what number on your system? This is the determine if we can re-produce the problem and eliminate the intermittent nature of your problem.
After that, we can look at taking sniffer traces to see if QoS markings are getting lost somewhere along the way.
Without knowing the above, your config has a lot of possibilities. Can't look at the dial-peers becasue there are three places that this gateway can receive calls. Don't know what IP Phone number the incoming call was trying to reach, etc.
