Hi, I have a customer that is heavily utilizing IPMA on CUCM 7.1.3. They have a 3rd party voicemail system which uses TAPI/Cisco TSP to send MWI to the phones rather than dialling the MWI on/off numbers. The problem I am now seeing is that the MWI will not work for the manager phones. This is the absolute worst group of phones that this could happen to as they are all directors! MWI works fine for all other non-manager phones including the assistants. I have assigned a 2nd line to some of them and have managed to at least get a flashing envelope but I am really looking for a fix rather than a workaround. I don't believe that there is actually an extension pushing the MWI to the phone. All we have is a CTI route point for the voicemail pilot which is controlled by TAPI and a park CTI route point and also one for the operator console queue. I have tried allowing these CTI route points to see the manager partition but still the MWI won't work on the manager phones.
Does anybody know of any fundamental reason why TAPI might not work to push MWI to manager phones in an IPMA system?
