Hi, We have a strange issue which is doing my head in. CUCM Version 9.1.2-10000-28 Arc Console Operator  5.1.4.1996 When some users are using CIPC softphones they do not appear to listed as available in the Operator Console, however some users who use CIPC softphones are appearing available in the Operator Console. I've narrowed it down to a CIPC related problem I believe because I asked them to login to a physical phone (we use EM) and seen that a user previously not available in the Console suddenly became available. So I've tried the following: 1) Restart of CTI Manager service on the CUCM where the Arc CTI related ports are registered to. This resolved an issue with users not appearing available in the Console before, but doesn't resolve this issue 2) Checked that the CIPC device association is in place on the End User, though it doesn't seem to matter as I have identified CIPC users who are displayed as available without this association in place. 3) Checked that Allow Control of CTI is enabled in all places (the line DN, the End user, the CIPC) 4) Compared a few CIPC configurations and couldn't see any noticeable difference between them. 5) Checked the user details in the Arc Console Operator program and the user is set up for BLF and has the correct device name associated under their contact details. Again, don't believe that the device name association is necessary either. At first I thought the reason for this was down to some of the users being logged into their physical phones, thus showing up in the console as registered, but the customer said they created two new users with CIPC only. One I have identified is available in the console and the other one is not showing as available. Judging by the dependency records, there does not appear to be any associations with other phones. Has anyone had this problem before and does anybody have any suggestions as to how I resolve it? Thanks in advance for any suggestions. Cheers ... View more
