Hi ,just put in a unity 2.4.6.135 to a call manager 3.0.10 with TSP 3.0.3 ,all works great except when a message is left instead of the mwi light coming on the phone just rings. The unity monitor shows MWI call with the source tele number but says its busy ,the debug from the call manager shows normal call to phone from voice mail ie no MWI light on message. The manual phone test works OK ,any ideas ? <br><br>
