Introduction

 

Cisco Unified CallManager serves as the software-based call-processing component of the Cisco Unified Communications family of products. A wide range of Cisco Media Convergence Servers provides high-availability server platforms for Cisco Unified CallManager call processing, services, and applications.

The Cisco Unified CallManager system extends enterprise telephony features and functions to packet telephony network devices such as IP phones, media processing devices, voice-over-IP (VoIP) gateways, and multimedia applications. Additional data, voice, and video services, such as unified messaging, multimedia conferencing, collaborative contact centers, and interactive multimedia response systems, interact through Cisco Unified CallManager open telephony application programming interface (API).

Cisco Unified CallManager provides signaling and call control services to Cisco integrated telephony applications as well as third-party applications. Cisco Unified CallManager performs the following primary functions:

• Call processing

• Signaling and device control

• Dial plan administration

• Phone feature administration

• Directory services

• Operations, administration, maintenance, and provisioning (OAM&P)

• Programming interface to external voice-processing applications such as Cisco IP Communicator, Cisco Unified IP Interactive Voice Response (IP IVR), and Cisco Unified CallManager Attendant Console

Key Features and Benefits

The Cisco Unified CallManager system includes a suite of integrated voice applications that perform voice-conferencing and manual attendant console functions. This suite of voice applications means that no need exists for special-purpose voice-processing hardware. Supplementary and enhanced services such as hold, transfer, forward, conference, multiple line appearances, automatic route selection, speed dial, last-number redial, and other features extend to IP phones and gateways. Because Cisco Unified CallManager is a software application, enhancing its capabilities in production environments requires only upgrading software on the server platform, thereby avoiding expensive hardware upgrade costs.

Distribution of Cisco Unified CallManager and all Cisco Unified IP Phones, gateways, and applications across an IP network provides a distributed, virtual telephony network. This architecture improves system availability and scalability. Call admission control ensures that voice quality of service (QoS) is maintained across constricted WAN link and automatically diverts calls to alternate public switched telephone network (PSTN) routes when WAN bandwidth is not available.

A web-browsable interface to the configuration database provides the capability for remote device and system configuration. This interface also provides access to HTML-based online help for users and administrators.

Cisco Unified CallManager release 5.1, designed to work like an appliance, refers to the following functions:

•Cisco Unified CallManager servers can get preinstalled with software to ease customer and partner deployment and automatically search for updates and notify administrators when key security fixes and software upgrades are available for their system.This process comprises Electronic Software Upgrade Notification.

• You can upgrade Cisco Unified CallManager servers while they continue to process calls, so upgrades take place with minimal downtime.

• Cisco Unified CallManager supports the Asian and Middle Eastern markets by providing support for Unicode on higher resolution phone displays.

• Cisco Unified CallManager provides Fault, Configuration, Accounting, Performance, and Security (FCAPS).

Browsing to Cisco Unified CallManager Administration

You access the Cisco Unified CallManager Administration program from a PC that is not the web server or has Cisco Unified CallManager installed. No browser software exists on the server. See the "Web Browsers" section for more information on browsing to the server.

Web Browsers

Cisco Unified CallManager Administration supports the following Microsoft Windows operating system browsers:

• Microsoft Internet Explorer (IE) 6.0

• Netscape 7.1

• From any user PC in your network, browse into a server that is running Cisco Unified CallManager Administration and log in with administrative privileges.Note: Simultaneous logon to Cisco Unified CallManager Administration by a large number of users can cause performance to suffer. Try to limit the number of users and administrators that are logged on simultaneously.

Note: Cisco Unified CallManager Administration does not support the buttons in your browser. Do not use the browser buttons (for example, the Back button) when you perform configuration tasks.

Cisco Unified CallManager Administration Logon

Use the following procedure to log on to Cisco Unified CallManager Administration.

Procedure

---

Step 1 Start your preferred operating system browser. Step 2 In the address bar of the web browser, enter the following case-sensitive URL: https://<Unified CM-server-name>:{8443}/ccmadmin/showHome.do where: <Unified CM-server-name> equals the name or IP address of the server

Note: You can optionally specify a port number.

Step 3 A Security Alert dialog box displays. Click the appropriate button. Step 4 At the Logon window, enter the application user password that you specified during Cisco Unified CallManager installation and click Submit. The Cisco Unified CallManager Administration window displays (see Figure 1-1).Note: For security purposes, Cisco Unified CallManager Administration logs you out after 30 minutes, and you must log back in.

Hypertext Transfer Protocol Over Secure Sockets Layer (HTTPS)

Hypertext Transfer Protocol over Secure Sockets Layer (SSL), which secures communication between the browser client and the web server (for Microsoft Windows users), uses a certificate and a public key to encrypt the data that is transferred over the internet. HTTPS also ensures that the user login password transports securely via the web. The following Cisco Unified CallManager applications support HTTPS, which ensures the identity of the server: Cisco Unified CallManager Administration, Cisco Unified CallManager Serviceability, the Cisco Unified CallManager User Options, Trace Collection Tool, the Real-Time Monitoring Tool (RTMT), and the XML (AXL) application programming interface.

A self-signed certificate gets generated on the web server at installation (the certificate also gets migrated during upgrades).

Note: If you access the web application by using the hostname and install the certificate in the trusted folder and then try to access the application by using the localhost or IP address, the Security Alert dialog box displays to indicate that the name of the security certificate does not match the name of the site.If you use the localhost, the IP address, or the hostname in the URL to access the application that supports HTTPS, you must save the certificate in the trusted folder for each of type of URL (with the local host, IP address, and so on); otherwise, the Security Alert dialog box displays for each type.

Using Internet Explorer and HTTPS with Cisco Unified CallManager Administration

The following section describes how to save the CA Root certificate in the trusted folder, so the Security Alert dialog box does not display each time that you access the web application. The first time that you (or a user) accesses Cisco Unified CallManager Administration or other Cisco Unified CallManager SSL-enabled virtual directories after the Cisco Unified CallManager 5.1 installation/upgrade from a browser client, a Security Alert dialog box asks whether you trust the server. When the dialog box displays, you must perform one of the following tasks:

• By clicking Yes, you choose to trust the certificate for the current web session only. If you trust the certificate for the current session only, the Security Alert dialog box displays each time that you access the application; that is, until you install the certificate in the trusted folder. • By clicking View Certificate > Install Certificate, you indicate that you intend to perform certificate installation tasks, so you always trust the certificate. If you install the certificate in the trusted folder, the Security Alert dialog box does not display each time that you access the web application. • By clicking No, you cancel the action. No authentication occurs, and you cannot access the web application. To access the web application, you must click Yes or install the certificate via the View Certificate > Install Certificate option. For other tasks that you can perform in the Security Alert dialog box, refer to the Cisco Unified CallManager Security Guide.

Procedure

---

Step 1 Browse to the application on the web server. Step 2 When the Security Alert dialog box displays, click View Certificate. Step 3 In the Certificate pane, click Install Certificate. Step 4 Click Next. Step 5 Click the "Place all certificates in the following store" radio button; click Browse. Step 6 Browse to Trusted Root Certification Authorities. Step 7 Click Next. Step 8 Click Finish. Step 9 To install the certificate, click Yes. A message states that the import was successful. Click OK. Step 10 In the lower, right corner of the dialog box, click OK. Step 11 To trust the certificate, so you do not receive the dialog box again, click Yes.

Note: If you use the localhost, the IP address, or the hostname in the URL to access the application that supports HTTPS, you must save the certificate in the trusted folder for each of type of URL (with the local host, IP address, and so on); otherwise, the Security Alert dialog box displays for each type.

---

Using Netscape and HTTPS with Cisco Unified CallManager Administration

When you use HTTPS with Netscape, you can view the certificate credentials, trust the certificate for one session, trust the certificate until it expires, or not trust the certificate at all.

Tip: If you trust the certificate for one session only, you must repeat the following procedure each time that you access the HTTPS-supported application. If you do not trust the certificate, you cannot access the application.

Perform the following procedure to save the certificate to the trusted folder:

Procedure

---

Step 1 Browse to the application, for example, Cisco Unified CallManager Administration, by using Netscape. The certificate authority dialog box displays. Step 2 Click one of the following radio buttons: • Accept this certificate for this session • Do not accept this certificate and do not connect • Accept this certificate forever (until it expires)

Note: If you choose Do not accept, the application does not display. Note: To view the certificate credentials before you continue, click Examine Certificate. Review the credentials, and click Close.

Step 3 Click OK. The Security Warning dialog box displays. Step 4 Click OK.

Configuring a Server

This section describes how to add or update a server address to the Cisco Unified CallManager database.

Before You Begin

The following guideline applies to adding a server: • Make sure that you only add each server once in the Server Configuration window. If you add a server using the host name and add the same server using the IP address, Cisco Unified CallManager cannot accurately determine component versions for the server after a Cisco Unified CallManager upgrade. If you have two entries in Cisco Unified CallManager Administration for the same server, delete one of the entries before you upgrade (see the "Deleting a Server" section).

Procedure

---

Step 1 Perform one of the following tasks: • To add a server, choose System > Server and click Add New. • To update a server, find the server by using the procedure in the "Finding a Server" section. The Server Configuration window displays. Step 2 Enter the appropriate settings as described in Table 2-1. Step 3 Click the Save icon that displays in the tool bar in the upper, left corner of the window (or click the Save button that displays at the bottom of the window) to save the data and to add the server to the database. Changes to the server configuration do not take effect until you restart Cisco Unified CallManager. For information about restarting the Cisco Unified CallManager service, refer to the Cisco Unified CallManager Serviceability Administration Guide.

Note: When you perform a fresh installation of Cisco Unified CallManager, you must define any subsequent servers (nodes) in the Cisco Unified CallManager Administration Server Configuration window before you can install the Cisco Unified CallManager software on each subsequent server. To define a subsequent node, click Add New, as described in Step 1 above, and configure the server. After you add the subsequent server, you can then install the Cisco Unified CallManager software on that server.

---

Deleting a Server

This section describes how to delete a server from the Cisco Unified CallManager database.

Before you delete the server, consider the following information: • In Cisco Unified CallManager Administration, you cannot delete the first node of the cluster, but you can delete subsequent nodes. • Cisco recommends that you do not delete any node that has Cisco Unified CallManager running on it, especially if the node has devices, such as phones, registered with it. • Although dependency records exist for the subsequent nodes, the records do not prevent you from deleting the node. To find out which Cisco Unified CallManagers are using the server, choose Dependency Records from the Related Links drop-down list box in the Server Configuration window and click Go. • If any call park numbers are configured for Cisco Unified CallManager on the node that is being deleted, the deletion fails. Before you can delete the node, you must delete the call park numbers in Cisco Unified CallManager Administration. • The system may automatically delete some devices, such as MOH servers, when you delete a server. • Before you delete a node, Cisco recommends that you deactivate the services that are active on the subsequent node. Performing this task ensures that the services work after you delete the node. • To delete a server and add it back to the cluster, see the "Deleting Then Adding Back a Server in Cisco Unified CallManager Administration" section.

Procedure

---

Step 1 To delete the server(s) from the Find and List Servers window, find the server by using the procedure in the "Finding a Server" section. The Find and List Servers window displays. Step 2 From the list of matching records, choose the server(s) that you want to delete. Step 3 Click the Delete Selected Item icon that displays in the tool bar in the upper, left corner of the window (or click the Delete Selected button that displays at the bottom of the window) to delete the server. Step 4 Cisco Unified CallManager Administration displays the following message: "You are about to permanently delete one or more servers. This action cannot be undone. Continue?". Click OK; the server gets deleted from the Cisco Unified CallManager database and is not available for use.

Tip If the Server Configuration window is displaying for a specific server, you can click Delete to delete the server. Cisco Unified CallManager Administration displays the following message: "You are about to permanently delete this server. This action cannot be undone. Continue?". Click OK; the server gets deleted from the Cisco Unified CallManager database and is not available for use.

Step 5 Reboot the servers in the cluster.

Tip If you delete a subsequent server and then want to add it back to the cluster, see the "Deleting Then Adding Back a Server in Cisco Unified CallManager Administration" section.

---

Deleting Then Adding Back a Server in Cisco Unified CallManager Administration Procedure

---

Step 1 In Cisco Unified CallManager Administration, add the deleted server, as described in the "Configuring a Server" section. Step 2 After you add the subsequent node to Cisco Unified CallManager Administration, you must install Cisco Unified CallManager on the node by using the 5.X disk that was provided in your software kit. If you have a 5.1(3) disk, perform a 5.1(3) installation on the node. If you have a disk with a previous version of 5.X on it (for example, 5.0(1), 5.0(4), 5.1(1), 5.1(2), and so on), use the 5.X disk to install Cisco Unified CallManager on the subsequent node; during the installation, choose the Upgrade During Install option when the 5.X installation displays the options.

Tip Make sure that the version that you install on the subsequent node matches the version that runs on the first node (publisher) in the cluster.

For example, if the first node in the cluster runs 5.1(3) and a service release (or engineering special), you must choose the Upgrade During Install option when the 5.X installation displays the installation options; before you choose this option, ensure that you can access the service release (or engineering special) image on DVD or a remote server. For more information on how to perform an installation, refer to the document, Installing Cisco Unified Communications Manager 5.1(3). Step 3 After you install Cisco Unified Communications Manager, configure the subsequent node, as described in Installing Cisco Unified Communications Manager 5.1(3).

---

Cisco Unified CallManager Configuration

Use Cisco Unified CallManager configuration to specify the ports and other properties for each Cisco Unified CallManager that is installed in the same cluster. A cluster comprises a set of Cisco Unified CallManagers that enables redundancy.

For the first node in a Cisco Unified CallManager cluster, the server gets automatically added as part of the installation. To add additional Cisco Unified CallManagers to a cluster, the administrator must configure a server (by using Server Configuration) and then add the Cisco Unified CallManager (by using Cisco Unified CallManager Configuration). This procedure is repeated for each Cisco Unified CallManager that is in the cluster.

Use the following topics to find and update a Cisco Unified CallManager configuration or to view system component version information:

• Finding a Cisco Unified CallManager • Updating a Cisco Unified CallManager • Cisco Unified CallManager Configuration Settings • Cisco CallManager Service Activation/Deactivation

Cisco CallManager Service Activation/Deactivation

The following requirements apply to Cisco CallManager service activation and deactivation:

• Cisco CallManager Service Activation

• Cisco CallManager Service Deactivation

Cisco CallManager Service Activation

When you perform a new Cisco Unified CallManager installation, you must follow these steps in sequence:

1. Add the Server. Cisco Unified CallManagers automatically get added when a server gets configured.

2. Activate the Cisco CallManager service, as described in the Cisco Unified CallManager Serviceability Administration Guide.

A message displays if you do not follow this sequence.

Cisco CallManager Service Deactivation

You can deactivate the Cisco CallManager service in Cisco Unified CallManager Serviceability. When you deactivate the Cisco CallManager service, the Cisco Unified CallManager where you deactivated the service becomes inactive for use.

Note From Cisco Unified CallManager Serviceability, you can view the status of the Cisco Unified CallManager by accessing Tools > Service Activation. When the Cisco CallManager service is deactivated, no one can make calls on that Cisco Unified CallManager.

You may still be able to perform configuration operations on a deactivated Cisco Unified CallManager if the Cisco CallManager Administration web service is active and the database is up and running.

When you reactivate the Cisco CallManager service on the Cisco Unified CallManager, the database automatically re-creates the Cisco Unified CallManager by retaining the original configuration (server name or IP address). This Cisco Unified CallManager then becomes active; you can verify that the Cisco CallManager service is running by accessing Tools > Control Center - Feature Services in Cisco Unified CallManager Serviceability.

For more information about Service Activation, refer to the Cisco Unified CallManager Serviceability System Guide and the Cisco Unified CallManager Serviceability Administration Guide.

Cisco Unified CallManager Group Configuration

A Cisco Unified CallManager Group specifies a prioritized list of up to three Cisco Unified CallManagers. The first Cisco Unified CallManager in the list serves as the primary Cisco Unified CallManager for that group, and the other members of the group serve as secondary and tertiary (backup) Cisco Unified CallManagers.

Each device pool has one Cisco Unified CallManager Group assigned to it. When a device registers, it attempts to connect to the primary (first) Cisco Unified CallManager in the group that is assigned to its device pool. If the primary Cisco Unified CallManager is not available, the device tries to connect to the next Cisco Unified CallManager that is listed in the group, and so on.

Cisco Unified CallManager Groups provide important features for your system:

•Redundancy—This feature enables you to designate a primary and backup Cisco Unified CallManagers for each group. •Call processing load balancing—This feature enables you to distribute the control of devices across multiple Cisco Unified CallManagers.

For most systems, you need to have multiple groups, and you need to assign a single Cisco Unified CallManager to multiple groups to achieve better load distribution and redundancy.

Use the following topics to add, update, or delete a Cisco Unified CallManager group:

• Finding a Cisco Unified CallManager Group • Configuring a Cisco Unified CallManager Group • Cisco Unified CallManager Group Configuration Settings • Deleting a Cisco Unified CallManager Group

Finding a Cisco Unified CallManager Group

Because you might have several Cisco Unified CallManager groups in your network, Cisco Unified CallManager Administration lets you locate specific Cisco Unified CallManager groups on the basis of specific criteria. Use the following procedure to locate Cisco Unified CallManager groups.

Deleting a Cisco Unified CallManager Group

This section describes how to delete a Cisco Unified CallManager Group from the database.

Before You Begin

Note: You cannot delete a Cisco Unified CallManager group if it is assigned to any device pools or MGCP gateways or if it is the current Auto-registration Cisco Unified CallManager Group for the cluster.

To find out which devices are using the Cisco Unified CallManager group, choose Dependency Records from the Related Links drop-down list box on the Cisco Unified CallManager Group Configuration window and click Go.

If the dependency records feature is not enabled for the system, the dependency records summary window displays a message that shows the action that you can take to enable the dependency records; the message also displays information about high CPU consumption that is related to the dependency records feature. For more information about dependency records, see the "Accessing Dependency Records" section.

If you attempt to delete a Cisco Unified CallManager group that is in use, an error message displays. Before deleting a Cisco Unified CallManager group that is currently in use, you must perform some or all of the following tasks:

• Assign a different Cisco Unified CallManager group to the device pools or MGCP gateways that currently use this Cisco Unified CallManager group. See the "Configuring a Device Pool" section.

• Create or choose a different Cisco Unified CallManager group to be the Auto-registration Cisco Unified CallManager Group.

Procedure

Step 1 Find the Cisco Unified CallManager group by using the procedure in the "Finding a Cisco Unified CallManager Group" section. Step 2 From the list of matching records, choose the group that you want to delete. Step 3 Click the Delete Selected Item icon that displays in the tool bar in the upper, left corner of the window (or click the Delete Selected button that displays at the bottom of the window) to delete the Cisco Unified CallManager group. Step 4 When asked to confirm the delete operation, click either OK to delete or Cancel to cancel the delete operation.

Phone NTP Reference Configuration

If you want to do so, you can configure phone Network Time Protocol (NTP) references in Cisco Unified CallManager Administration to ensure that a Cisco SIP IP Phone gets its date and time from the NTP server. If all NTP servers do not respond, the SIP phone uses the date header in the 200 OK response to the REGISTER message for the date and time.

After you add the phone NTP reference to Cisco Unified CallManager Administration, you must add it to a date/time group. In the date/time group, you prioritize the phone NTP references, starting with the first server that you want the phone to contact.

The date/time group configuration gets specified in the device pool, and the device pool gets specified on the phone page.

Use the following topics to configure phone NTP references:

• Finding the Phone NTP References

• Configuring the Phone NTP References

• Phone NTP Reference Configuration Settings

• Deleting the Phone NTP Reference

Finding the Phone NTP References

Because you can configure several phone NTP references in Cisco Unified CallManager Administration, Cisco Unified CallManager Administration allows you to locate specific phone NTP references. Use the following procedure to locate the phone NTP references that exist in Cisco Unified CallManager Administration.

Deleting the Phone NTP Reference

This section describes how to delete a phone NTP reference from the Cisco Unified CallManager database.

Before You Begin

Before you can delete the phone NTP reference from Cisco Unified CallManager Administration, you must delete the phone NTP reference from the date/time group. To find which date/time groups use the phone NTP reference, choose Dependency Records from the Related Links drop-down list box in the Phone NTP Reference Configuration window and click Go. When you know which date/time groups use the phone NTP reference, you can then remove that phone NTP reference from that group.

If the dependency records feature is not enabled for the system, the dependency records summary window displays a message that shows the action that you can take to enable the dependency records; the message also displays information about high CPU consumption that is related to the dependency records feature. For more information about dependency records, refer to the "Accessing Dependency Records" section.
