I am running CUCM 8.5.1 with CUPS 8.5.4. I have configured three 7965 phones for testing. I have installed the messaging service and can send IMs from phone to phone, phone to one of the clients or client to phones. I have set them all to play a tone upon receipt. One phone will play the tone and display the message on the main display. The other two pones only display the message within the phone messenger service under the messages selection with no tone. I have tried to do my do diligence in checking my settings and they appear all be the same configs between all the phones but yet i can not get the other phones to display the message on the main screen.
Any suggestions as to what might be causing this or how to resolve would be appreciated. Can provide additional info on request to further clarify.
Thanks,
