You must install the Phone Selection plug-in for the user
on IM and Presence, the Microsoft Server Type value is
"MOC Server OCS", and
the user has multiple devices (lines), and
on Microsoft OCS, the LINE URI for the user does not uniquely
identify a line appearance (for example, there is no device=, or partition=, or
both, in the LINE URI)
You cannot use the Phone Selection plug-in if you are running the
remote call control feature with Microsoft LCS 2005 because Microsoft LCS 2005
does not support customized tabs. If you are using Microsoft LCS 2005, the
remote call control feature uses the device selection logic on
IM and Presence to determine the device to control. In the
Cisco Unified CM IM and Presence Administration GUI, select
Application > Microsoft
RCC > Settings, and select the
Microsoft Server Type value
MOC Server LCS.
For this procedure you will require the Phone Selection
plug-in installer file
Cisco MOC RCC Plug-in.msi, which you can download from
Cisco Unified CM IM and Presence Administration. Select
Application > Plugins
and download the
Cisco Unified CM IM and Presence MOC Remote Call Control
Run the following command on the client PC, where CUPFQDN value
specifies the FQDN of your
IM and Presence server:

Microsoft Office Communicator, and
verify that the
IM and Presence tab connects and displays on the interface.
Troubleshooting Remote Call Control
Microsoft Office Communicator Users Hear Two Beeps for Each DTMF
When running Microsoft Office Communicator with Remote Call
Control, users can select Cisco IP Communicator as their phone device.
In this scenario, when a user makes a call and enters DTMF
tones (for example, when entering a voicemail password), the DTMF tones beep
twice for each button press—once from Microsoft Office Communicator and once
from Cisco IP Communicator. This is normal and expected behavior when DTMF is
negotiated in-band; it does not happen if DTMF is negotiated out-of-band.
User unable to switch selected device from Cisco Unified IP Phone to Cisco IP Communicator
This problem can occur if you have configured the device
name for Cisco IP Communicator to be the same as the Cisco Unified
Communications manager username. This is not a supported configuration, and you
should change the device name for Cisco IP Communicator to a unique name.
Remote Call Control is Not Working
If Remote Call Control is not working for the
Microsoft Office Communicator users,
and the SIP Proxy service is not processing incoming messages from the
Microsoft Office Communicator Server, check the following:
This can be caused by a high number of simultaneous sign in
Microsoft Office Communicator after
Microsoft OCS. When many of these attempts are made
concurrently, the SIP Proxy service is flooded with INVITES and INFO messages.
Notify users about the service outage and recommend that they sign
Microsoft Office Communicator
during this time.
Stop the SIP Proxy service.
Restart the Microsoft OCS.
Restart the SIP Proxy service.
Notify users that they must sign in again to ensure that Remote
Call Control is working properly.
Microsoft Office Communicator Client Cannot Connect to the IM and Presence Tab
Microsoft Office Communicator client
cannot connect to the
IM and Presence tab, check the following:
You may have specified an invalid IP address or FQDN for your
IM and Presence server. Repeat the plug-in installation procedure,
specifying the correct
IM and Presence server address in the command in Step 1.
If you experience tab connection problems, note the following:
You may need to add the web address of the
IM and Presence server to the list of trusted web addresses in the browser
on the client PC. In Microsoft Internet Explorer,
Options > Security > Trusted
Sites, and add the web address
https://<IM and Presence_server_name> to the list of trusted web addresses.
You may need to add the HTTPS web address of your domain to
the security zone of the
IM and Presence server. In Microsoft Internet Explorer, select
Options > Security > Local
intranet > Sites > Advanced,
and add the entry
https://*.your-domain to the list of web
addresses for the security zone.
If an error message displays informing users that they do not have
permission to use this feature, you need to enable users for
Microsoft Office Communicator on
IM and Presence.
Problems Installing the Plug-in on Microsoft Vista
If you are running a Microsoft Vista platform and you
experience problems installing the plug-in, you may need to turn off User
Access Control (UAC) on the client PC. Follow this procedure to turn off UAC:
Sign in to the client PC with the credentials of a member of the
local Administrators group.
Start > Control
Panel > User Accounts.
User Accounts in the User Accounts pane.
Turn User Account Control On or Off in the
User Accounts task pane.
If UAC is currently configured in Admin Approval Mode, the User
Account Control message displays. Select
Use User Account Control (UAC) to help protect your
Select Restart Now to apply the change.
