Chapter 2 Configuring the Cisco Unified IP Phone for MIDlets

MIDlets Troubleshooting Tips

Note If you are upgrading from an older XML specification identifier (XSI) user interface to MIDlets, you must reset the phone and reset the CTS to allow the Java MIDlets application to work with the Cisco Unified IP Phone. See the “Managing Phone Reset and Codec Connectivity” section on page 4-13for reset information.

Setting Phone URL Parameters for MIDlets

Make sure the default services URL is set for MIDlets. To override default settings:

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

Step 2 Choose System > Enterprise Parameters Configuration.

Step 3 In the Phone URL Parameters box, set the URL Services in the following format:

http://xx.xx.xx.xx:8080/ccmcip/getservicesmenu.jsp

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

Note You may use a hostname providing the CTS and the phone is provisioned with a DNS name server.

Step 4 Click Save to save your settings.

MIDlets Troubleshooting Tips

•If the MIDlet does not come up at all, verify that the Unified CM is subscribed. Reset the phone.

•Verify that the phone has the correct firmware for that MIDlet.

•Verify that the CTS has the correct image for that MIDlet.

•If the MIDlet comes up with a blank white screen, verify that the Service URL for the phone is blank.

•If the phone fails to register, verify that phone type is set correctly. For example, Cisco Unified IP Phone 7970 should not be set as 7975.

•If the phone is stuck in the initializing phase, restart TSPS on the CTS. If after the restart the phone shows “phoneui=xsi,” reboot the CTS.

•Check the Service URL. If it ends with “services.html,” make it blank and apply changes. Reboot the CTS.

•If no services appear on the phone, even though subscribed to a valid service, check the “Services Provisioning” field to make sure it is set to Default.

•If the MIDlet fails to start, make sure that the Enable box checked.

•Make sure the service that you are using to subscribe your phone is pointing to the correct JAD file.

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.
