Hmm, have a few BRI's but no E1's on asterisk (just on an old samsung) but we've never had echo troubles, even without an echo can. (Yes in melbourne, both CBD and surrounds)
The clicking sounds like a clock issue, or not enough cpu. What are your phones, maybe it's acoustic echo. Are you seeing any odd log messages (with debug=10 and verbose=10)?
