Chapter 2 Configuring the Cisco Unified IP Phone for MIDlets

Configuring MIDlets

The following describes the necessary Service URL content:

–xx.xx.xx.xx is the IP address of the Unified CM server.

–y-y-y-is the version of the MIDlet application being added to Unified CM.

–YY is the build version of the MIDlet application being added to Unified CM.

e.Service Category—Required. Choose Java MIDlet from the drop-down menu.

f.Service Type—Required. Choose Standard IP Phone Service.

g.Service Vendor Name—Must be exactly “Cisco” (case-sensitive).

h.Service Version—Leave blank.

Step 6 Click the Enable check box.

Step 7 Click Save to save your changes.

Configuring the MIDlets IP Phone Interface

The Cisco Unified IP Phone auto-configures the IP address of the CTS; the CTS obtains the phone IP address using CDP data and the CTS sends the command to the Cisco Unified IP Phone to start the MIDlet. The system launch command specifies the IP address of the CTS.

To configure each Cisco Unified IP Phone 7970 Series to run the MIDlet IP phone interface:

Step 1 Log in to the Cisco Unified CM Administration interface.

Step 2 From the Navigation drop-down menu in the upper right corner, choose Cisco Unified CM Administration and click Go.

Step 3 From the Device drop-down menu, choose Phone. The Find and List Phones Page appears.

Step 4 Search for a phone using the fields provided or choose a phone from the drop-down menu and click Find. A list of devices appears.

Step 5 Click on a device in the Device Name (Line) column. The Phone Configuration page for that device appears.

Step 6 From the Related Links drop-down menu in the upper right corner, choose Subscribe/Unsubscribe Services and then click Go. The Subscribed Cisco IP Phone Services window for that device appears.

Step 7 In the Service Information box, choose MIDlet IP phone service from the Select a Service drop-down list and click Next. The Subscribed Cisco IP Phone Services window is updated with configurable Service Name and ASCII Service Name fields.

Step 8 Click Subscribe to save your settings or Back to return to the original Subscribed Cisco IP Phone Services window.

If the phone is already subscribed to an older MIDlet version:

a.Unsubscribe the phone from the older service.

b.Subscribe the phone to the new IP phone service that you created in the “Creating MIDlets IP Phone Service in Unified CM” section on page 2-16.

Step 9 Click Save to save your settings.

OL-21851-01 specifications

Cisco Systems OL-21851-01 refers to a specific certification exam related to Cisco's networking technologies, particularly within the field of enhanced security and network management. This exam is a part of the Cisco Certified Network Associate (CCNA) certification, designed to validate foundational knowledge and skills required to implement, operate, and troubleshoot small-to-medium sized networks.

One of the main features of the OL-21851-01 exam is its comprehensive coverage of essential networking concepts. Candidates are tested on their understanding of network fundamentals, including OSI and TCP/IP models, IP addressing and subnetting, and different networking protocols. It also emphasizes the importance of identifying and mitigating network vulnerabilities, in light of the increasing need for cybersecurity in modern infrastructures.

The exam incorporates a strong focus on Cisco's proprietary technologies, specifically Cisco IOS, which is the operating system that runs on a wide range of Cisco devices. Understanding Cisco IOS commands and configurations is critical for success in this exam, as they are integral to managing and optimizing network devices.

Another key aspect of OL-21851-01 is the emphasis on automation and programmability within networking environments. Candidates learn about modern automation tools and methods that help streamline network management tasks and enhance operational efficiency. This reflects the industry's shift toward Software-Defined Networking (SDN), which supports the need for flexibility and simplified network operations.

In addition to technical skills, the exam also assesses candidates' ability to implement network security measures. This includes configuring firewalls, access control lists (ACLs), and intrusion prevention systems (IPS) to protect network resources from potential threats. The knowledge of how to monitor and troubleshoot network performance using Cisco tools is also a critical requirement.

To succeed in the OL-21851-01 exam, candidates are encouraged to leverage Cisco's extensive resources, including training courses, study materials, and hands-on labs. Engaging in practical lab scenarios is particularly beneficial, as it allows candidates to apply theoretical knowledge in real-world contexts, reinforcing their skills in network design and management.

In conclusion, Cisco Systems OL-21851-01 is an essential certification for aspiring networking professionals, providing a robust foundation in networking principles, security practices, and modern automation techniques that are pivotal for managing today’s complex networking environments effectively.
