Release Notes for Cisco Conference Connection 1.2

These release notes include up-to-date documentation notes and descriptions of known problems for Cisco Conference Connection version 1.2.

These release notes provide the following information:

Documentation Roadmap

Use these publications to learn how to install and use Cisco Conference Connection. All Cisco Conference Connection documents are available online at:


  • Cisco Conference Connection Administration Guide (DOC-7814554=)—Describes how to plan for, install, configure, manage, use, and troubleshoot Cisco Conference Connection. An Adobe Acrobat (PDF) version of this manual is available in the Cisco Conference Connection online help.
  • Cisco Conference Connection User's Guide—Describes how to use Cisco Conference Connection to create and manage conferences. The guide is only available online at the above URL, or in a PDF file available on the Cisco Conference Connection Information page.

What's New in Cisco Conference Connection 1.2

These are the major new features and other changes in Cisco Conference Connection 1.2:

  • Metalink agreements no longer required—In Cisco Conference Connection 1.1, user information was kept in a separate directory from the Cisco CallManager directory. Keeping this directory up-to-date required a metalink agreement with the Cisco CallManager directory.

In Cisco Conference Connection 1.2, the separate directory is eliminated and user information is accessed directly from the Cisco CallManager directory. This eliminates the need for the metalink agreement.

  • Enhanced directory support—Because Cisco Conference Connection now draws information directly from the Cisco CallManager directory, you can now use any type of directory that Cisco CallManager supports. In Cisco Conference Connection 1.1, you had to use the DC directory.
  • Integrated user management—All user information is now accessed from the Cisco CallManager directory. Thus, all user management is done in Cisco CallManager. The ability to create and list users has been eliminated from Cisco Conference Connection.
  • No guest user—Cisco Conference Connection 1.2 eliminates the concept of a guest user. All users defined in the Cisco CallManager directory can log into Cisco Conference Connection as regular users (that is, they can create conferences).
  • Change to administrators—Cisco Conference Connection 1.2 uses a different method of identifying administrators. If you have a list of administrators for a 1.1 server, that list will not be valid for 1.2. To log in the first time as an administrator, you must log in using the cccadmin user name (which you must define in Cisco CallManager). Then, you can create a new list of administrators based on Cisco CallManager user names (the old list of administrators is preserved for your convenience).
  • Password-protection for conferences—Owners can now set passwords for conferences, thus increasing the security of sensitive conferences. Administrators can also enforce security policies (each of these is independent of the others):
    • You can force owners to set passwords for new or changed conferences.
    • You can force owners to select randomly generated passwords.
    • You can hide all password-protected conferences.
    • You can set a default password to protect conferences that do not have owner-assigned passwords.
  • End-of-conference announcement—Cisco Conference Connection now gives you a five-minute notice that a conference will end.
  • IP Phone Service changes—The Cisco Conference Connection IP Phone Service works differently in this release to accommodate password-protected conferences. The service prompts for the owner-supplied password if a conference is configured with one. Also, the gateway prefix no longer appears in the conference list.

Upgrading from Cisco Conference Connection 1.1

If you are upgrading a Cisco Conference Connection 1.1(3) server, follow the instructions in Cisco Conference Connection Administration Guide for upgrading the product. Ensure that you completely remove metalink agreements and uninstall the software, as described in the administration guide, before you install Cisco Conference Connection 1.2.

You must configure these items to complete the upgrade:

  • The cccadmin user—To log into Cisco Conference Connection 1.2 as an administrator (for the first time), you must use the cccadmin user name. You must create cccadmin in Cisco CallManager before you can use the name. See the administration guide for information on creating the cccadmin user.
  • Updating the administrator list—The Cisco Conference Connection administrators you configured in 1.1 no longer apply in 1.2. You must create a new list of administrators based on Cisco CallManager user names. The administration guide explains how to do this; the software preserves your old list of administrators to help you create the new list.
  • Set a default password (optional)—The Conference Director IVR application now includes a default password parameter. If you set a default password, then conference attendees must enter a password for every conference, even if the conference owner does not set a password. If you decide that this level of security is required, update the Conference Director configuration as described in the administration guide.
  • Configure password requirements (optional)—Through the Cisco Conference Connection web interface, you can force conference owners to set passwords for all new or modified conferences. You can also force owners to select randomly-generated passwords, rather than passwords they select. Finally, you can choose whether all conferences with passwords are also hidden conferences. See the administration guide for more information on these system settings.

Cisco Conference Connection Known Problems

Known problems are unexpected behaviors or defects in the product. They are graded according to severity level. These release notes contain information about some of the more likely known problems that you might encounter.

You can search for additional known problems on the Cisco bug tracking system tool, called Bug Toolkit. To access Bug Toolkit, open http://www.cisco.com/support/bugtools in your web browser.

Table 1 describes restrictions or other known issues for using Cisco Conference Connection 1.2.

Table 1   Cisco Conference Connection Known Problems

Bug ID Summary Explanation


Callers experience up to a 15 second delay before the system plays the welcome prompt.

This occurs after a Cisco CallManager server fails over to a secondary server.

If a Cisco CallManager server fails over, advise Cisco Conference Connection users that they will experience a delay before the system plays the welcome prompt.


Database subsystem shows status OUT_OF_SERVICE on the Application Administration Engine status page, but the system is processing calls and validating database steps.

You may see this problem if you log in to the Application Administration web pages before the SQL server starts the DCMS database used by Cisco Conference Connection.

This problem does not affect callers.

To work around this problem, restart the engine from the Application Administration Engine status page. This will refresh the DB subsystem status. While the Engine is restarting, callers will be unable to initiate new conferences.


A conference may run indefinitely.

If a participant leaves a conference during a Cisco CallManager restart or failover, Cisco Conference Connection may assume that the participant is still present. As long as the conference has a participant and there are resources available, the system will extend the conference automatically.

To prevent this problem, schedule a 10 minute conference call during off hours that requires all available licenses. This will force all calls and conferences in progress to be terminated.


Unsupported endpoints may experience one-way audio.

This problem can occur when using an endpoint that is not supported by Cisco CallManager to directly dial into a conference. For more information about supported endpoints, refer to the Cisco CallManager System Guide.

To work around this problem, dial into the conference via a gateway, or use a Cisco CallManager supported endpoint.


Users cannot log in to Cisco Conference Connection and administrators cannot access the User Administration page.

This happens when the primary Cisco CallManager fails over to a secondary Cisco CallManager and the LDAP directory is unavailable. The directory is not available until the primary Cisco CallManager is returned to service.

To work around this problem, postpone scheduling and user administration tasks until Cisco CallManager fails back to the primary server.


The Cisco Conference Connection database exceeds the allowed size

User synchronization or other database operation fails because the PRIMARY file group is full. New pages cannot be allocated.

To work around this problem, use the Start Program button in Windows Explorer to restart Cisco Conference Connection. The system runs a utility program that removes past records from the resource table.


Cisco Conference Connection will not start after an upgrade or reinstall due to an incorrect database password.

During a reinstall or upgrade of Cisco Conference Connection, you need to provide the correct database password. If you provide the incorrect password, Cisco Conference Connection will not start.

To work around this problem, use the Cisco Conference Connection password update utility to correct the database password.

The utility is installed on the Cisco Conference Connection server in the following directory:

C:\Program Files\Cisco\ConferenceConnection\server\pwdupdate.vbs1

After you update the password, restart Cisco Conference Connection.


G.729 calls to Cisco Conference Connection do not receive transcoding resources when using Cisco Voice Gateway 200 (VG 200).

In IOS, make sure the PreferredMillisecondPacketSize value for the VG200 is set to 20 or 30 ms.


Callers hear echo when calling into conferences through the Cisco Catalyst 6608 gateway.

Please call TAC to get the latest information on this issue.


Can't start Cisco Conference Connection on Phones with Shared Lines


Phone A has line 1 and Line 2 (shared). Phone B has Line 1 (shared) and Line 2. When Phone A is active on Line 1, Phone B gets a "Line in Use" message when attempting to start a conference call using the Services button.

There does not appear to be a way to get Phone B to use Line 2 even though Line2 is available.

If Phone B tries to select Line2 Before starting the call, Phone B gets stuck in a loop for 30 seconds. During this time, no features work.

There are several suggestions to work around this problem.

1) Always configure primary line as a first line on the phone, and then shared line as a second line

2) Load the latest version of the Cisco IP Phone Firmware available.


Conference participants hear broken audio, often while other participants are logging in to the conference.

This might happen when other participants are calling into the conference and are in the process of entering DTMF digits, or using other features that involve the Application Engine.

To work around this problem, turn off all debug tracing on the Application Administration Engine web page. Use debug tracing only to investigate problems and only for short periods of time. Leave alarm tracing turned on.


Unable to access the Application Administration web page after installation or upgrade.

This may occur as a result of an obsolete ccndir.ini file. The Conference Connection server refers to the ccndir.ini file to locate the LDAP server. If the IP address for the LDAP server changes while the Cisco Conference Connection server is offline for an installation or upgrade, the ccndir.ini file is not updated with the new location.

To work around this problem, delete the ccndir.ini file on the Cisco Conference Connection server. This file is located in the following directory:

c:\WINNT\system32\ccn\ccndir.ini file


The system reports that the JTAPI subsytem is OUT_OF_SERVICE after installation. This occurs even after upgrading the Cisco CallManager plug-in.

The version of the JTAPI client bundled with Cisco Conference Connection may not be compatible with the version of Cisco CallManager you are using.

To work around this problem, stop the Application Engine and uninstall the JTAPI client on the Cisco Conference Connection server using Add/Remove Programs. Then reboot the Cisco Conference Connection server and install the JTAPI client version that is bundled with Cisco CallManager.

Ensuring Audio Quality

If conference participants hear echo, jittery voices, or clipped voices, it may be due to a problem on the network. These problems are more likely when participants join a conference through gateways and in a highly routed or switched environment.

Cisco recommends taking the following precautions to ensure conference audio quality:

  • Ensure that your voice network implementation is consistent with quality of service (QoS) guidelines.
  • Connect the Cisco Conference Connection server directly to a switch port.
  • Configure the switch port to run at 100Mbps Full Duplex (do not set it for automatic detection).
  • Configure the Network Interface Card (NIC) on the Cisco Conference Connection server to run at 100Mbps Full Duplex mode.
  • Disable Voice Activity Detection (VAD).
  • Upgrade your gateway firmware to the latest version published on CCO.
  • Make sure that network routing is giving priority to voice.
  • Turn off Application tracing.
