In Cisco Unified Communications Manager (CUCM), regions play a critical role in determining the quality and reliability of voice and video calls between different locations. In this article, we will discuss the importance of regions and how they are used in CUCM.
Regions in CUCM define the characteristics of the audio and video codecs used for calls between different locations. The codecs used for voice and video calls can have different characteristics such as bandwidth, packetization interval, and compression. Regions are used to ensure that calls between locations are optimized for the available network bandwidth and quality.
Regions can be used to set limits on the maximum bandwidth used for calls between different locations, which can prevent congestion on the network. Regions also allow for the prioritization of voice and video traffic over other network traffic, ensuring that calls receive the necessary bandwidth and quality of service to function correctly.
Regions can be configured in CUCM to optimize calls between different locations based on the available network bandwidth and the requirements of the endpoints involved. For example, if two endpoints are located in different regions with different codec settings, CUCM will automatically select the appropriate codec for the call based on the bandwidth and other network conditions. This ensures that the call quality is optimal for the available network conditions.
Additionally, regions can be used to control the types of calls that are allowed between different locations. For example, an organization may wish to prevent video calls between locations with limited bandwidth or video conferencing equipment. By setting the region settings appropriately, CUCM can prevent these types of calls from being initiated.
In summary, regions are a critical component of Cisco Unified Communications Manager that enables the optimal routing and quality of voice and video calls between different locations. By configuring regions appropriately, organizations can ensure that their voice and video calls are optimized for the available network bandwidth and quality, and that the quality of service for these calls is prioritized over other network traffic.
