The Cisco SRST (Survivable Remote Site Telephony) feature is a crucial component for businesses that rely on uninterrupted voice communication. The key to understanding its capabilities and limitations lies within the Cisco Srst Datasheet. This document provides a comprehensive overview of the supported features, hardware requirements, and configuration parameters necessary to ensure business continuity during WAN outages.
Decoding the Cisco Srst Datasheet Functionality
The Cisco Srst Datasheet acts as a blueprint for implementing and managing SRST in a Cisco Unified Communications environment. It provides detailed information on the specific Cisco routers and gateways that support the SRST feature, outlining their capacity in terms of the number of supported IP phones and concurrent calls. Understanding these limitations is paramount for planning and scaling your SRST deployment effectively. The datasheet enables administrators to select the appropriate hardware based on the specific needs of each remote site. This includes:
- Maximum number of supported IP phones
- Supported codecs
- Compatibility with Cisco Unified Communications Manager versions
Beyond hardware specifications, the Cisco Srst Datasheet also details the software features available within the SRST environment. This includes information on call routing, dial plan configuration, and supported telephony features such as call hold, transfer, and conferencing. It also specifies security protocols, such as SRTP for secure voice communication during an outage. It’s essential to review this information to ensure that the necessary features are available to maintain essential business operations during a WAN failure. The important aspects of SRST include:
- Call Forwarding
- Call Hold
- Transfer functionalities
The Cisco SRST datasheet includes details about the versions of software and firmware that are supported by the devices. This includes minimum and maximum versions of Cisco IOS and other relevant software. Keeping these version numbers up-to-date ensures compatibility with the Cisco Unified Communications Manager and protects against known vulnerabilities. Here is a short example:
| Software | Minimum Version |
|---|---|
| Cisco IOS | 15.0(1)M |
To fully understand and correctly apply the information contained in the Cisco Srst Datasheet, it’s highly recommended to consult the official Cisco documentation related to your specific hardware and software versions. These documents offer detailed configuration examples and troubleshooting tips that can significantly aid in a successful SRST deployment and maintenance.
