Information About Ad Hoc Conferencing

About Voice Ports for Ad Hoc Conferencing

The number of available ad hoc voice ports on the system is determined by the installed maxadhoc license port count.

Ad hoc voice ports are utilized in the following situations:

One port is utilized for each endpoint that is conferenced into a voice call that includes three or more endpoints. Note that a direct, voice-only call between two endpoints does not utilize any ad hoc voice ports.

One port becomes utilized when a Cisco Unified IP Phone creates a meet-me conference.

For each additional endpoint that calls into the meet-me conference, another port becomes utilized.

One voice port is utilized for each utilized video port.

About Video Ports for Ad Hoc Conferencing

The number of available ad hoc video ports on the system is determined by the maxadhoc and the stdvideoconf license port count. One ad hoc video port is utilized for each video endpoint in a call.

The actual number of usable ad hoc video ports on the system depends on what Video maximum bit rate you have configured:

At the default bit rate of 320 kbps, the number of usable of ad hoc video ports is equal to the installed stdvideoconf license port count.

If you decrease the Video maximum bit rate, the number of usable of ad hoc video ports stays at the installed stdvideoconf license port count.

If you increase the Video maximum bit rate to 704 kpbs, then the system decreases the number of available ad hoc video ports according to the following formula:

number of available ad hoc video ports = maxadhoc license port count / 3

For example, if the maxadhoc license port count is set to 60 and the Video maximum bit rate is increased to 704, then the number of available ports is 20.


Note This change only takes affect after you save the values on the Ad Hoc Conferencing Configuration page.


If you do not install the stdvideoconf license, then the default six video ports are not affected by changes to the Video maximum bit rate.

To display the number of ad hoc video ports that are currently available on your system, see the Max streams supported at this bit rate read-only field on the Ad Hoc Conferencing Configuration page.

About Ad Hoc Video

Cisco Unified MeetingPlace Express includes a software-based video mixer that switches the video streams based on the current active speaker, as determined by the software-based audio mixer on the same server. The voice-activated display includes only one video stream at a time (1x1 layout) using Common Intermediate Format (CIF) dimensions.

The video stream of the active speaker is sent to all endpoints in the conference, and the video stream of the previous speaker is sent to the current active speaker. When only one endpoint is in the conference, then that endpoint displays its own video stream.

How to Configure Ad Hoc Conferencing

Restrictions for Ad Hoc Video

In each video conference, all participating endpoints are dynamically adjusted to use the same video bit rate. If participants join the conference using different video bit rates, then Cisco Unified MeetingPlace Express sends flow-control messages that instruct endpoints to lower their bit rates to match the lowest-speed endpoint.

All participating video endpoints are dynamically adjusted to use the codec that is configured in the Video codec field. Video endpoints that do not support the configured codec cannot join any video conferences.

Recommendations for Ad Hoc Video

The video mixer switches the video stream to the current active speaker, which is the loudest speaker as determined by the audio mixer. Therefore, users in a video call may experience poor or confusing video switching results if any participating endpoints generate loud background noises.

Provide the following recommendations to end users that may participate in video calls:

If you are only listening (and not speaking), then mute your phone.

Do not use a speakerphone, which may generate echoes, ringing sounds, or audio feedback.

If you use a microphone that is built into your video camera, then keep the camera away from fans, vents, and other sources of noise.

For softphones, such as Cisco Unified Personal Communicator with a Cisco VT Camera or Cisco IP Communicator with Cisco Unified Video Advantage:

Do not use the microphone that is built into your computer. These microphones tend to pick up a lot of background noise.

We highly recommend that you use a headset that is equipped with a microphone.

Whenever multiple microphones are available, make sure that your computer and video endpoint are configured to use the desired microphone.

For example, suppose that you use Cisco Unified Personal Communicator with a Cisco VT Camera on a Windows XP system, and that you have a headset that is equipped with a microphone. To make sure that your system is configured to use the headset microphone, choose Start > Control Panel > Sounds and Audio Devices. Then click the Audio tab, and make sure that your headset is selected as the sound recording device.

See the documentation for your specific endpoint product to optimize audio settings and resolve audio problems.

How to Configure Ad Hoc Conferencing

To configure ad hoc conferencing, you must configure both Cisco Unified CallManager and Cisco Unified MeetingPlace Express. Once both products are configured, Cisco Unified MeetingPlace Express registers with Cisco Unified CallManager to report the number of video ports that can be supported, the configured video codec to use, and the configured minimum and maximum video bit rates. Similarly, Cisco Unified CallManager sends Cisco Unified MeetingPlace Express an XML configuration file that contains the parameters that you configure in Cisco Unified CallManager.

Topics in this section include:

Configuring Cisco Unified MeetingPlace Express for Ad Hoc Conferencing

This topic describes how to configure ad hoc conferencing on the Cisco Unified MeetingPlace Express server.

Before You Begin

Read the following sections:

Prerequisites for Ad Hoc Conferencing

Restrictions for Ad Hoc Conferencing


Caution Changing these configuration parameters causes the Cisco Unified MeetingPlace Express system to clear all active calls and meetings. The system then cancels the current registration with Cisco Unified CallManager and reregisters using the new configuration parameters.

Procedure


Step 1 Log in to Cisco Unified MeetingPlace Express.

Step 2 Click Administration at the top of the page.

Step 3 On the left side of the page:

a. Click System Configuration.

b. Click Call Configuration.

c. Click Ad Hoc Conferencing Configuration.

Step 4 Enter or change the values in the fields, which are described in the "Fields on the Ad Hoc Conferencing Configuration Page" section.

At a minimum, configure the following fields:

SCCP enabled—Select Yes.

Primary TFTP server—Enter the IP address of the primary Cisco Unified CallManager server on which the TFTP service is running.

Backup TFTP server 1—Enter the IP address of a backup Cisco Unified CallManager server on which the TFTP service is running.

Step 5 Write down or copy the value in the MAC address field, which you need to add the Cisco Unified MeetingPlace Express server a the conference bridge in Cisco Unified CallManager.

Step 6 Click Save.

Step 7 Proceed to the "Configuring Cisco Unified CallManager to Use Cisco Unified MeetingPlace Express as a Conference Bridge" section.

Configuring Cisco Unified CallManager to Use Cisco Unified MeetingPlace Express as a Conference Bridge

This topic describes how to configure the Cisco Unified CallManager server to identify the Cisco Unified MeetingPlace Express server as a Cisco video conference bridge.

Before You Begin

Read the following sections:

Prerequisites for Ad Hoc Conferencing

Restrictions for Ad Hoc Conferencing

Complete the task described in the "Configuring Cisco Unified MeetingPlace Express for Ad Hoc Conferencing" section.

This task is performed in the Cisco Unified CallManager Administration pages. Because the pages and menus vary by Cisco Unified CallManager release, you may need to see the Cisco Unified CallManager Administration online help for more accurate step-by-step instructions than those provided in this procedure. The following procedure refers to Cisco Unified CallManager release 4.1.

Procedure


Step 1 Go to http://ccm-server/ccmadmin/main.asp, where ccm-server is the fully qualified domain name or IP address of the Cisco Unified CallManager server.

Step 2 Log in with your Cisco Unified CallManager administrator username and password.

Step 3 In the menu at the top of the Cisco Unified CallManager Administration page, click Service > Media Resource > Conference Bridge.

Step 4 In the top right corner of the page, click Add a New Conference Bridge.

Step 5 Select the Cisco Video Conference Bridge (IPVC-35xx) type.

Step 6 In the Conference Bridge Configuration page, configure the fields described in Table 6-1.

Table 6-1 Fields for Adding A New Conference Bridge to Cisco Unified CallManager 

Conference Bridge Configuration Field
Action

MAC Address

Enter the Cisco Unified MeetingPlace Express MAC address, which you obtained in Step 5 of the "Configuring Cisco Unified MeetingPlace Express for Ad Hoc Conferencing" section. Or see the "Determining the MAC Address of your System" section.

Example:1231123245AB

Device Pool

If no device pools are defined, then select Default.

If the Cisco Unified CallManager deployment utilizes customer-defined device pools, then either create a new device pool or choose an existing device pool for a region with a codec that is compatible with the conferencing bridge. Currently, Cisco Unified MeetingPlace Express supports only the G.711 audio codec.

The device pool specifies a collection of properties for this device including Cisco Unified CallManager Group, Date/Time Group, and Region.


Step 7 (Optional) Configure the fields in the Product Specific Configuration area.

To view field descriptions and help for product-specific configuration items, click the "i" information icon to the right of the Product Specific Configuration heading to display help in a popup dialog box.

The Registration Info fields are used to create an XML configuration file that is automatically downloaded and used to configure Cisco Unified MeetingPlace Express during registration with Cisco Unified CallManager.

Step 8 Click Insert.

At this point in the configuration process, Cisco Unified MeetingPlace Express registers with Cisco Unified CallManager. Once the Status field displays "Registered" on the Ad Hoc Conferencing Configuration page in the Administration Center, the Cisco Unified MeetingPlace Express conference bridge becomes available for Cisco Unified CallManager ad hoc conferences.

If you also want to enable Cisco Unified CallManager meet-me conferences, then proceed to the following step.

Step 9 (Optional) Configure the Cisco Unified MeetingPlace Express conference bridge to be used for meet-me conferences by completing the following high-level tasks in Cisco Unified CallManager:

a. Add or update one or more meet-me number patterns.

b. Add or update a media resource group (MRG) to include the MAC Address that you configured in Step 6.

c. Add or update a media resource group list (MRGL) to include the MRG that you configured in Step 9b.


Note Cisco Unified CallManager always uses the first resource found in the MRGL. If a voice-only conference bridge is placed at the top of the MRGL, then Cisco Unified CallManager Express always uses that conference resource first, even if the call requires video. Therefore, position this MRG at the top (highest-priority position) of the MRGL.


d. Configure each phone (voice or video endpoint) to the MRGL that you configured in Step 9c.

For details on completing these high-level tasks, see the administration guide and system guide for your specific Cisco Unified CallManager release. You can find this documentation at http://www.cisco.com/en/US/products/sw/voicesw/ps556/prod_maintenance_guides_list.html.
