I have 2 3300 CX controllers running 9.0 UR2 Both using embedded messaging.. I am trying to setup a call flow that will allow someone to reach someone in system B from an MLAA menu. When I try to put the extension of the remote user in the MLAA form, the system tells me that this is not a valid mailbox orext on this system. Does anyone know a way to do this...im sure this is a pretty common scenario. I tried setting up a speed call on the local system but it wont let you send the call to the speedcall ext.
