Software Conference Bridge settings

Conference Bridge for Cisco Unified Communications Manager, a software or hardware application, allows both ad hoc and meet-me voice conferencing. Each conference bridge can host several simultaneous, multiparty conferences.

Be aware that both hardware and software conference bridges can be active at the same time. Software and hardware conference devices differ in the number of streams and the types of codec that they support.

You cannot add software conference bridges to Cisco Unified Communications Manager by using Conference Bridge Configuration. Software conference bridges automatically get added when a Cisco Unified Communications Manager server gets added. After a Cisco Unified Communications Manager server gets added, the software conference bridge gets displayed in the Find/List Conference Bridges window (by default, the first software conference bridge gets configured during Cisco Unified Communications Manager installation) when you perform a search. You can update software conference bridges, but you cannot delete them.

See the Cisco Unified Communications Manager System Guide for more information about conference bridges.

The following table describes the software conference bridge configuration settings.

Table 1 Software conference bridge configuration settings

Field

Description

Conference Bridge Type

This field automatically displays Cisco Conference Bridge Software.

Host Server

This field automatically displays the Cisco Unified Communications Manager server for this software conference bridge.

Conference Bridge Name

This field automatically displays the software conference bridge name. The format of the name specifies CFB_ followed by a digit that represents the value of the software conference bridge; for example, CFB_3 represents the third conference bridge in the Cisco Unified Communications Manager system.

Description

This field automatically displays a description, but the administrator can update this field.

Device Pool

Choose a device pool that has the highest priority within the Cisco Unified Communications Manager group that you are using or choose Default.

Common Device Configuration

Choose the common device configuration to assign to the conference bridge. The common device configuration includes attributes, such as MOH audio source, that support features and services for phone users.

Device configurations that are configured in the Common Device Configuration window display in the drop-down list.

Location

Use locations to implement call admission control (CAC) in a centralized call-processing system. CAC enables you to regulate audio quality and video availability by limiting the amount of bandwidth that is available for audio and video calls over links between locations. The location specifies the total bandwidth that is available for calls to and from this location.

From the drop-down list box, choose the appropriate location for this conference bridge.

A location setting of Hub_None means that the locations feature does not keep track of the bandwidth that this conference bridge consumes. A location setting of Phantom specifies a location that enables successful CAC across intercluster trunks that use H.323 protocol or SIP.

To configure a new location, use the System > Location menu option.

For an explanation of location-based CAC across intercluster trunks, see the Cisco Unified Communications Manager System Guide.

Use Trusted Relay Point

From the drop-down list box, enable or disable whether Cisco Unified CM inserts a trusted relay point (TRP) device with this media endpoint. Choose one of the following values:

  • Default—If you choose this value, the device uses the Use Trusted Relay Point setting from the common device configuration with which this device associates.
  • Off—Choose this value to disable the use of a TRP with this device. This setting overrides the Use Trusted Relay Point setting in the common device configuration with which this device associates.
  • On—Choose this value to enable the use of a TRP with this device. This setting overrides the Use Trusted Relay Point setting in the common device configuration with which this device associates.

A Trusted Relay Point (TRP) device designates an MTP or transcoder device that is labeled as Trusted Relay Point.

Cisco Unified CM places the TRP closest to the associated endpoint device if more than one resource is needed for the endpoint (for example, a transcoder or RSVPAgent).

If both TRP and MTP are required for the endpoint, TRP gets used as the required MTP. See topics related to TRP insertion in Cisco Unified Communications Manager in the Cisco Unified Communications Manager System Guide for details of call behavior.

If both TRP and RSVPAgent are needed for the endpoint, Cisco Unified CM first tries to find an RSVPAgent that can also be used as a TRP.

If both TRP and transcoder are needed for the endpoint, Cisco Unified CM first tries to find a transcoder that is also designated as a TRP.

The Cisco TelePresence MCU is a high-definition (HD) multipoint video conferencing bridge. It delivers up to 1080p at 30 frames per second, full continuous presence for all conferences, full trans-coding, and is ideal for mixed HD endpoint environments.

The Cisco TelePresence MCU supports SIP as the signaling call control protocol. It has a built in Web Server that allows for complete configuration, control and monitoring of the system and conferences. The Cisco TelePresence MCU provides XML management API over HTTP.

Cisco TelePresence MCU allows both ad hoc and meet-me voice and video conferencing. Each conference bridge can host several simultaneous, multiparty conferences.

See the Cisco Unified Communications Manager System Guide for more information about conference bridges.

The following table describes the Cisco TelePresence MCU configuration settings.

Table 9 Cisco TelePresence MCU configuration settings

Field

Description

Conference Bridge Name

Enter a name for your conference bridge

Destination Address

Enter the IP Address of the Cisco TelePresence MCU conference bridge

Description

Enter a description for your conference bridge

Device Pool

Choose a device pool or choose Default.

Common Device Configuration

Choose the common device configuration to assign to the conference bridge. The common device configuration includes attributes, such as MOH audio source, that support features and services for phone users.

Device configurations that are configured in the Common Device Configuration window display in the drop-down list.

Location

Use location to implement call admission control (CAC) in a centralized call-processing system. CAC enables you to regulate audio quality and video availability by limiting the amount of bandwidth that is available for audio and video calls over links between locations. The location specifies the total bandwidth that is available for calls to and from this location.

From the drop-down list box, choose the appropriate location for this conference bridge.

A location setting of Hub_None means that the locations feature does not keep track of the bandwidth that this conference bridge consumes. A location setting of Phantom specifies a location that enables successful CAC across intercluster trunks that use H.323 protocol or SIP.

To configure a new location, use the System > Location menu option.

For an explanation of location-based CAC across intercluster trunks, see the Cisco Unified Communications Manager System Guide.

Use Trusted Relay Point

From the drop-down list box, enable or disable whether Unified Communications Manager inserts a trusted relay point (TRP) device with this media endpoint.

  • Default—If you choose this value, the device uses the Use Trusted Relay Point setting from the common device configuration with which this device associates.
  • Off—Choose this value to disable the use of a TRP with this device. This setting overrides the Use Trusted Relay Point setting in the common device configuration with which this device associates.
  • On—Choose this value to enable the use of a TRP with this device. This setting overrides the Use Trusted Relay Point setting in the common device configuration with which this device associates.

A TRP device designates an MTP or transcoder device that is labeled as Trusted Relay Point.

Cisco Unified CM places the TRP closest to the associated endpoint device if more than one resource is needed for the endpoint (for example, a transcoder or RSVPAgent).

If both TRP and MTP are required for the endpoint, TRP gets used as the required MTP. See the Cisco Unified Communications Manager System Guide for details of call behavior.

If both TRP and RSVPAgent are needed for the endpoint, Cisco Unified CM first tries to find an RSVPAgent that can also be used as a TRP.

If both TRP and transcoder are needed for the endpoint, Cisco Unified CM first tries to find a transcoder that is also designated as a TRP.

See the Cisco Unified Communications Manager System Guide for a complete discussion of network virtualization and trusted relay points.

SIP Interface Info

MCU Conference Bridge SIP Port

This is the SIP listening port of the Cisco TelePresence MCU Conference Bridge. The default value is 5060.

SIP Profile

From the drop-down list box, choose Standard SIP Profile for TelePresence Conferencing.

SIP Trunk Security Profile

From the drop-down list box, choose the security profile to apply to the SIP trunk.

You must apply a security profile to all SIP trunks. Cisco Unified Communications Manager provides a default nonsecure SIP trunk security profile for autoregistration. To enable security features for a SIP trunk, configure a new security profile and apply it to the SIP trunk. If the trunk does not support security, choose a nonsecure profile.

To identify the settings that each profile contains, choose System > Security Profile > SIP Trunk Security Profile.

If you are using SRTP with Cisco TelePresence MCU, the SIP trunk security profile must use the following settings:

  • Device Security Mode must be Encrypted
  • Incoming Transport Type and Outgoing Transport Type must be TLS
  • X.509 Subject Name must be set to the defined Common Name that is used in the Cisco TelePresence MCU certificates

For information on how to configure security profiles, see the Cisco Unified Communications Manager Security Guide.

SRTP Allowed

Check the SRTP Allowed check box if you want Cisco Unified Communications Manager to allow secure and nonsecure calls with Cisco TelePresence MCU.

If you do not check this check box, Cisco Unified Communications Manager prevents SRTP negotiation with the Cisco TelePresence MCU and uses RTP instead.

For more information on encryption, see the Cisco Unified Communications Manager Security Guide.

Note    When this check box is checked, the vcs-interop script is selected by default in the Script drop-down list box and the Enable Trace check box is checked.
Note    If you check this check box, you must configure TLS so that you do not expose keys and other security-related information during call negotiations.

Normalization Script info

Script

Choose the script from the drop-down list box that you want to apply.

To import another script for Cisco TelePresence MCU, go to the SIP Normalization Script Configuration window (Device > Device Settings > SIP Normalization Script), and import a new script file.

Enable Trace

Check this check box to enable tracing within the script or uncheck this check box to disable tracing. When this box is checked, the trace.output API that is provided to the Lua scripter produces an SDI trace.

Note   

Cisco recommends that you enable tracing only while debugging a script. Tracing has an impact on performance and should not be enabled under normal operating conditions.

Parameter Name/Parameter Value

(Optional) Enter parameter names and parameter values. Valid values include all characters except equal signs (=), semicolons (;), and nonprintable characters, such as tabs. You can enter a parameter name with no value.

Example
Parameter Name Parameter Value
CCA-ID 11223344
pbx
location RTP

You must choose a script from the Normalization Script drop-down list box before you can enter parameter names and values.

To add another parameter line, click the + (Plus) button. To delete a parameter line, click the – (Minus) button.

HTTP Interface Info

Username

Enter the Cisco TelePresence MCU administrator username.

Password

Enter the Cisco TelePresence MCU administrator password.

Confirm Password

Enter the Cisco TelePresence MCU administrator password.

Use HTTPS

Check this check box if you want to create a secure HTTPS connection between Cisco Unified Communications Manager and Cisco TelePresence MCU. The default HTTPS port is 443.

For information on how to create a TLS connection between Cisco Unified Communications Manager and Cisco TelePresence MCU, see topics related to setting up a TLS connection with Cisco TelePresence MCU.

HTTP Port

Enter the Cisco TelePresence MCU HTTP port. The default port is 80.

Note

The HTTP configuration must match what is configured on the Cisco TelePresence MCU. This information allows Cisco Unified Communications Manager to invoke the remote management API on the Cisco TelePresence MCU.

CSCub65671 Route Class Configuration SIP Information

If the route pattern points to a SIP trunk supporting G.Clear, then specify Data or Hotline as the Route Class.

You can use non-default route class settings to translate an inbound T1 CAS route class digit into a Cisco Unified Communications Manager route class value (and strip off the digit). You should not need to assign a non-default route class setting to any other inbound calls that use pattern configuration.
