---

Note IP Phone Information Facility might not be available on your IP Telephony Monitor (ITM) desktop; it is installed when Incremental Device Update (IDU) 2 or later is installed. For information about installing IDUs, see the "Device Support" section.

---

Through IP Phone Information Facility, IP Telephony Monitor (ITM) helps you monitor, track, and maintain IP phones in your network.

Unlike the conventional phone that has only a physical relationship with the PBX, an IP phone has relationships with more than one entity—the switch and the Cisco CallManager. In the PBX world, the conventional phone was entirely managed through the PBX. With IP Telephony (IPT), an IP phone has a physical relationship with a switch and a logical relationship with a Cisco CallManager.

Both the physical and logical relationships of an IP phone must be maintained for the IP phone to function. Using IP Phone Information Facility, ITM gives you a combined view of both of these relationships and makes it easy for you to track and solve IP phone problems.

These topics explain how to use IP Phone Information Facility:

•Getting Started with IP Phone Information Facility

•Working With IP Phone Information Facility Displays

•Finding IP Phones

•Displaying IP Phone Details

•Working with IP Phone Discovery

---

Note For ITM Multi-View users only: You might not receive accurate data if the Cisco CallManager and switch for an IP phone are in different partitions, or if either is in a partition other than the one in which the IP phone is grouped.

---

Getting Started with IP Phone Information Facility

IP Phone Information Facility appears when you select IP Telephony Monitor > IP Phone Information Facility.

With IP Phone Information Facility, you can do the following:

•Find the IP phones in your network. For details on finding phones, see the "Finding IP Phones" section.

•Display details on the IP phones in your network.

For details on each display, see the following sections:

–IP Phone Detail Display

–SRST Configuration Detail Display

–IPT Applications Detail Display

•Set the IP phone collection schedule. For details, see the "Scheduling Major Phone Discovery" section.

•View IP phone collection status. For details, see the "Viewing IP Phone Discovery Status" section.

Working With IP Phone Information Facility Displays

IP Phone Information Facility has two types of displays: those that result from a Find or Advanced Find operation, and various IP phone detail displays. Both types provide information beyond the initial display.

The following sections describe how to access and work with IP Phone Information Displays:

•Working With the Find and Advanced Find Displays

•Opening a Web Interface on an IP Phone

Working With the Find and Advanced Find Displays

The Find IP Phone Detail display and Advanced IP Phone Detail display appear in new browser windows, in printable format.

In all reports, the extension number, IP address, and MAC address are hyperlinks that open the IP phone web interface. This web interface provides device information, network configuration details, ports information, Ethernet information, and so on for the specified IP phone. For further details, see the "Opening a Web Interface on an IP Phone" section.

Refreshing the Data

To refresh the display with the latest data, close the display and generate it again. If you merely refresh your browser window, the time of display generation does not change. This indicates that the data in the display is not refreshed.

The IP Phone Audit Detail and IP Phone Move Detail displays obtain their data from IP Phone Movement Tracking (Minor Discovery), which runs every 5 minutes. Therefore, you can run these displays and obtain fresh data about once every 5 minutes.

Getting More Information About an IP Phone

To get more information about an IP phone, you can click the extension number, IP Address, or MAC Address, which are hyperlinks. These hyperlinks take you to the IP phone page that displays device information, network configuration details, ports information, Ethernet information, and so on for the specified IP phone. For details, see the "Opening a Web Interface on an IP Phone" section.

Opening a Web Interface on an IP Phone

The IP phone web interface provides detailed information about an IP phone. This interface opens through the URL located on the IP phone.

You can open this web interface using the hyperlinks (extension number, IP address, MAC address) in the various reports that you generate using IP Phone Information Facility. By launching this web interface, you get information directly from the IP phone.

Finding IP Phones

You can locate IP phones in your network using extension numbers, IP addresses, MAC addresses, and several other search criteria, such as Cisco CallManager addresses, switch addresses, Survivable Remote Site Telephony (SRST) router addresses, IP phone models, VLAN names, VLAN IDs, SRST status, and IP phone status (unregistered or registered with the Cisco CallManager).

These topics provide information on how to use the Find IP Phones facility:

•Finding IP Phones Using the Find Option

•Finding IP Phones Using the Advanced Find Option

Finding IP Phones Using the Find Option

Using the Find option, you can locate an IP phone in the network using any of these attributes:

•Extension number

•IP address

•MAC address

---

Step 1 Select IP Telephony Monitor > IP Phone Information Facility > Find IP Phones > Find. The Find IP Phone dialog box appears.

Step 2 In the Find phone by list, select one of these attributes:

•Extension number

•IP address

•MAC address

Step 3 After you have selected the attribute type, enter a value in the field, and click View.

For example, if you selected Extension, enter the extension number of the IP phone in the attribute field, and click View.

The IP Phone Details page appears in a new browser window, in printable format. The extension number, IP address, and MAC address are hyperlinks that open the IP phone web interface.

Use the print function of your browser to print out the report.

To see additional records that may exist for your specified attribute, click Next.

Figure 5-1 shows an example of the IP Phone Details page. Table 5-1 describes the information displayed on the IP Phone Details page.

Tips

•For the Cisco Wireless IP Phone 7920 to be monitored in ITM, its Aironet access point must also be monitored by ITM. Only the logical information from the Cisco CallManager will be displayed for this phone. All the switch information for the 7920 will appear as Not Available. In Cisco CallManager releases prior to 4.0, the 7920 appears as a 7960. Therefore, ITM also displays the 7920 as a 7960 for Cisco CallManager releases prior to 4.0. No other features (such as IP Phone Audit, IP Phone Move, or Unregistered Suspect Phone detail displays) are supported for the Cisco Wireless IP Phone 7920.

•If the search result for an IP phone is zero, see if any of the following situations exist:

–Either the switch or the Cisco CallManager (or both) with which the phone is associated is not monitored by ITM.

–If you have ITM Multi-View and the Cisco CallManager and switch for an IP phone are in different partitions, or the Cisco CallManager or switch for an IP phone are in a partition other than the one in which the IP phone is grouped.

If you have ITM Multi-View, make sure that the phone, its Cisco CallManagers, and its switches all are on the same partition. Check and make any necessary changes.

•If Cisco IP SoftPhone records do not appear, generate the IPT Applications Detail display. See the "IPT Applications Detail Display" section.

•If N/A appears in a field instead of data, it means either of the following:

–The switch or the Cisco CallManager is not monitored by ITM. To correct this condition, add the unmonitored switch or Cisco CallManager to ITM.

–ITM cannot get the information from the switch or the Cisco CallManager. To correct this condition, check the status of the switch or Cisco CallManager in the Alerts and Activities display. If the switch or Cisco CallManager is unreachable, make sure that the connectivity is restored.

•You may not be able to see the list of Cisco CallManagers or switches in the popup window that appears when you click the following icon:

This occurs when PIFServer is down. Do the following:

–Check the status of PIFServer by using the command pdshow PIFServer from the command line.

–If PIFServer is down, use the CiscoWorks start function. To do this:

1. Select Server Configuration > Administration > Process Management > Start Process.

2. Select the PIFserver process from the pull-down menu.

Alternatively, you can bring PIFServer up using the command pdexec PIFServer from the command line. Use this approach if, for example, the webserver is down.

Working with IP Phone Discovery

This section describes the following:

•Overview of IP Phone Discovery

•Scheduling Major Phone Discovery

•Viewing IP Phone Discovery Status

Overview of IP Phone Discovery

ITM does two types of phone discovery:

•Major—Discovers and collects information about all the IP phones in the network, correlating the information, and storing it in the database.

•Minor—Checks all the switches and Cisco CallManagers and identifies changes. IP Phone Movement Tracking (Minor Discovery) automatically runs every five minutes. This five-minute interval is not configurable. For more information, see the "IP Phone Movement Tracking (Minor Discovery)" section.

IP Phone Information Facility discovers only those IP phones connected to switches and Cisco CallManagers monitored by IP Telephony Monitor (ITM). It does not discover devices.

IP Phone Information Facility does not provide an interface through which to add devices. To discover any IP phones connected to devices not currently being discovered by IP Phone Information Facility, you must add those devices to ITM. For details on adding devices, see the "Adding a Device" section.

If you add a switch or a Cisco CallManager to ITM, IP Phone Information Facility will perform a major phone discovery. If you add an IP phone to an already monitored switch, that phone will be picked up in the next 5-minute cycle of IP Phone Movement Tracking.

To discover the IP phone data from the network, IP Phone Information Facility does the following:

1. Collects the module and port information for all access switches.

2. Collects the mapping between VLAN and port information.

3. Uses the CDP cache and Bridge table to determine the end hosts connected to the switch.

4. Gets the list of IP phones from the Cisco CallManager.

5. Associates the switch data with the data from the Cisco CallManager and stores it in the database.

---

Tip The following problems can occur during IP phone discovery:

•Discovery takes a long time. This could be because of the following:

–There are too many unreachable devices in the network.

–You have configured a large number of VLANs on the switches. These VLANs are not used.

Check and make any necessary changes.

•Discovery does not seem to be working properly. Discovery begins automatically when you restart PIFServer. If you find a problem with discovery, do the following:

1. Check the status of PIFServer using the command pdshow PIFServer from the command line.

If PIFServer is down, use the CiscoWorks start function:

Select Server Configuration > Administration > Process Management > Start Process, and select the PIFserver process from the pull-down menu.

Alternatively, you can start PIFServer by using the command pdexec PIFServer from the command line. (Use this approach if, for example, the webserver is down.)

2. Under NMSROOT\logs\itemLogs, check the pif.log file for errors. If the file shows no errors, check the pifapp.log file. For details on viewing log files, see the "Viewing and Maintaining Log Files" section.

---

Scheduling Major Phone Discovery

You should run a major phone discovery whenever there are network-wide changes, or when the VLAN settings are changed. To get the current information on the changes in your network, you should ideally configure major phone discovery to be run every six to eight hours in a normal network. If the network is stable, one discovery during nonbusy hours of the network should suffice. For details on scheduling resource intensive tasks, see the "Performing Scheduling Tasks" section.

For discovery to function correctly, you must enable Cisco Discovery Protocol (CDP) for devices in the network.

If one discovery takes longer than scheduled, the next discovery occurs at the next scheduled interval. For example, if you have scheduled discovery to take place every 10 minutes but for some reason it takes 12 minutes, then the next discovery will happen at the next scheduled interval; that is, after 8 minutes.

You can schedule a major discovery of IP phones in your network using the Collection Schedule option. However, when you start PIFServer for the first time, or restart it, major phone discovery takes place automatically.

---

Note There are six default schedules, and you are limited to a total of ten schedules. Any of the schedules can be edited or deleted.

---

Your login determines whether you can see the IP Phone Discovery Schedule page. For more details about user roles, see the "Understanding Your User Role" section.

Using the IP Phone Discovery Schedule page is described in the following sections:

•Creating an IP Phone Discovery Schedule

•Modifying an IP Phone Discovery Schedule

•Deleting an IP Phone Discovery Schedule

Creating an IP Phone Discovery Schedule

There are six default IP phone discovery scheduels, and you can add up to ten additional schedules.
