I believe he's referring to the DTMF dialing bug(s) present in 6.0. I'm eagerly installing PR5 at a site tonight that has had intermittent "your call cannot be completed as dialed" messages and even calls being sent to the wrong place, despite the correct digits being dialed as viewed by call history and reports. FWIW - using ARS avoids the bug but directly choosing a trunk group or a trunk will trigger the bug.

Mitel obviously did little to no loopstart testing when they released 6.0. The first releases of 6.0 even had static and feedback in loopstarts, fixed in PR2.
