Cisco Unified Communications is a comprehensive set of integrated solutions for voice, video, and data communication. It provides a single platform for users to communicate, collaborate, and share information from anywhere, at any time.
A dial plan is a set of rules that determines how phone numbers are translated into meaningful destinations. In a Cisco Unified Communications system, the dial plan defines how calls are routed within the system and to the PSTN.
The different types of endpoints include IP phones, softphones, video endpoints, and specialized endpoints such as paging systems and intercoms. Each endpoint is designed to provide a different level of functionality and flexibility.
QoS (Quality of Service) is the ability to prioritize certain types of traffic on a network. In VoIP, QoS is critical to ensure that voice traffic is given the highest priority, so there is no degradation in call quality or dropped calls.
A codec is a software algorithm that compresses and decompresses audio or video signals. In VoIP, codecs are used to reduce the bandwidth requirements for voice traffic without compromising quality. The choice of codec can also impact call quality and network bandwidth utilization.
The first step in troubleshooting call quality is to isolate the problem. This may involve checking the network infrastructure, checking the endpoints, or analyzing call records. Once the problem has been identified, the next step is to implement a solution, which may involve adjusting QoS policies, tweaking codec settings, or identifying and fixing hardware or software issues.
H.323 and SIP are two protocols used in VoIP communications. H.323 is an older protocol that is often used in legacy systems, while SIP is a newer protocol that is more efficient and adaptable. SIP is also more popular in Cisco Unified Communications systems.
An SRST router is a router that is used as a backup in the event of a failure in the Cisco Unified Communications system. SRST stands for Survivable Remote Site Telephony, and it allows users to continue making and receiving calls even in the event of a failure in the main system.
CUCM (Cisco Unified Communications Manager) is the core component of a Cisco Unified Communications system. It provides call processing, call routing, and call management services for voice, video, and data communications. CUCM is critical to the overall functioning of the system, and it is important for a Cisco Voice Engineer to have a strong understanding of how it works.
There are several ways to ensure security in a Cisco Unified Communications system, including implementing strong password policies, encrypting voice traffic, enabling firewalls, and implementing access control. It's important to have a comprehensive security plan in place to protect against attacks and unauthorized access.
In conclusion, these are some of the most common Cisco Voice Engineer interview questions and answers to help you prepare for your next interview. It's important to have a strong understanding of Cisco Unified Communications, as well as VoIP protocols, codecs, and quality of service.
