Cisco CCNA Voice certification has been developed to build the professionals in such a way so that they can have the administration capabilities over a voice network. The certification is patterned in a rigorous manner so that the concepts and the technical aspects introduced can be absorbed by the candidates and then implemented in real life voice administering jobs. The certification is completely updated with the requirements of voice network administrations. Employers are always on the search for employees who can provide something extra to the organization. Hence, a certified voice admin can be very vital in the functioning of the organization.
Who can do this certification?
Network professionals who want to get themselves certified with a professional degree on voice administration must do this certification.
A CCNA voice certified professional will get extra emphasis on the job market. The salary scale will differ for a professional degree holder. Hence, the voice network engineer will be able to secure a higher post in some of the reputed organizations. Furthermore, the competencies developed during the course of the study will also help him in implementing the tasks better.
Candidates need to sit for a single paper namely: Introducing Cisco Voice and Unified Communications Administration (ICOMM).
According to the examinations body any valid Cisco CCENT, Cisco Switching and Routing and Cisco CIE certification could act as a prerequisite.
Study materials required for preparation are available online. Online training centers provide CCNA voice PDF lecturewhich helps the students in revising for the topics. There is also a CCNA voice study guide PDF that provides an outline of the topics to be covered for the exam. In addition to that CCNA voice official exam certification guide PDF is supplied by Cisco. However, students must give plenty of mock and practice tests before appearing in the exam.
The course consists of the following components:
- Components of the Cisco Unified Communications Architecture
- PSTN components and technologies
- VoIP components and technologies
- Gateways, voice ports, and dial peers to connect to the PSTN and service provider networks
- Configuring Cisco network to support VoIP
- Implementing UC500 using Cisco Configuration Assistant
- Implementing Cisco Unified Communications Manager Express to support endpoints using CLI
- Implementingvoicemail features using Cisco Unity Express
The syllabus introduces its candidates with a wide range of technology and infrastructure. The detailed conditions related to a Unified Conditions environment are elaborated in the first part of the syllabus. The second part of the syllabus makes the candidates looks into the PSTN technology and its components. This makes the candidates to know about time division and statistical multiplexing. The candidates should also learn about the analog and digital voice circuits in this section.
Detailed mechanisms behind the VoIP component and technologies are elaborated in this syllabus and it is required that the candidates should have a solid understanding of the concepts of VoIP. In addition, technical terms like RTP, RTCP, MGCP, SIP, SCCP and voice packetization are also introduced in the course syllabus. Candidates must exhibit the practical knowledge necessary to configure gateways, voice ports and Cisco network for supporting the VoIP mechanism. Another technology named UC500 is also introduced to the candidates. The concepts of UC500 are linked with the previously learned concepts. This helps in the successful implementation of the UC500 using the Cisco Configuration Assistant. Implementing CUIME and voicemail features are also the mechanisms that are looked upon in this certification. This opens up additional technicalities like the DHCP, NTP and TFTP. The software and hardware components that are needed in successfully implementing the above mentioned procedure are also taught during the training.
The technical aspects of the syllabus are covered in training sessions. Many candidates get themselves enrolled in online practical training classes whereas some gain the experience in real life by going in labs where training is provided. Boot camps also help the candidates in learning about the technical know hows.
Validity of the certification
3 years is the validity period of the certificate. However, to maintain the validity any one of the following steps could be followed:
- Passing an associate level exam
- Passing another current professional level exam
- Passing another current Cisco Specialist exam
- Passing another current CCIE Written exam
- Passing another current CCDE Written exam or CCDE Practical exam
- Passing the Cisco certified architect certification exam
The associate level certification program is specifically structured to meet the needs of the constantly changing industry. The content and training provided makes the students fully equipped to work in dynamic and challenging environment. They could gain a cutting edge in the field of network engineering.
