We are nearing the end of or OCS integratiion with our Mitel 3300 and have one bug that we cannot iron out. When we place a call from our "OCS Testuser" using the microsoft office communicator client to another user internally, the calling-parties display name appears correctly on the called-parties office communicator client, but on their Mitel desk phone the E.164 format is displayed. Any guidence would be greatly appreciated.
