You must install the Phone Selection plug-in for the user if:
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 Plugin.
Run the following command on the client PC, where CUPFQDN value specifies the FQDN of your IM and Presence server:
If you do not specify the FQDN of your IM and Presence server in this command the plug-in installation will be aborted.
Follow the installation instructions to install to finish installing the Phone Selection plug-in.
Launch 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 Tone
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 attempts on Microsoft Office Communicator after restarting the
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 out of 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
If the 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, select Internet 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 Internet 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.
Select Start > Control Panel > User Accounts.
Select User Accounts in the User Accounts pane.
Select 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 Continue.
Uncheck Use User Account Control (UAC) to help protect your computer.
Select Restart Now to apply the change.
