Where in Cisco UCM is restrictions on audio bandwidth configured?

While locations are used in conjunction with regions for Call Admission Control (CAC) and bandwidth management, the direct configuration of audio bandwidth restrictions (codec bitrate) is performed at the region level, not directly on the location.

Partitions are used for call routing and privacy, defining which directory numbers a device can dial or be dialed from, not for configuring audio bandwidth restrictions.

Cisco UCM utilizes regions to define the characteristics of devices located within a specific area, including audio codec bandwidth. By associating devices and gateways with regions, and then configuring the inter-region audio bandwidth, administrators can control the maximum bitrate for audio calls between different regions, effectively managing network bandwidth consumption.

Serviceability is a set of tools and features within UCM primarily for monitoring, alarming, and troubleshooting, not for configuring call routing or media parameters like audio bandwidth.
