We recently upgraded our T1 from CAS to PRI and are now receiving inbound caller id. When a call comes in it hits our Unity Caller Handler via CM since we are using Unity as our AutoAttendant. When the call is received to our 7912s and 7970s we see the caller # with no problem on our phone display. On our 7912s if we look at our missed calls or received calls we see the external # with no problem. On our 7970s we see missed calls and received calls as coming from Voicemail and one of our voicemail ports. Does anyone know why this is working differently between the phones. I'm running 6-0-2-sr1, CM 4.0.2a and Unity 4.0.4 sr1.
