We got back to 1.8.32.3 and all worked properly with the same dialplan. We were able to reproduce  this error on stand alone server with Asterisk 11.22.0 compiled with appropriate flags for obtaining backtrace. As we noted error occur in the queue when user with Cisco SPA303 (version 7.5.4) accepts the call, puts it on hold by hold button (hand is depicted on the button), accepts the next call and returns from hold.
