Platform and Protocol Support for Unified E-SRST Features

Overview

This document provides information on the compatibility of Unified Survivable Remote Site Telephony features (for Unified SRST, Unified E-SRST, and Unified Secure SRST) across the Cisco Routers. Feature support is detailed by protocol and platform and was last updated for Cisco IOS XE 17.14.1a Release (Unified SRST Release 14.4).

For information on the Cisco IOS XE and Cisco IOS Release mapping with Unified SRST, see Unified CME, Unified SRST, and Cisco IOS Software Version Compatibility Matrix.

For information on feature description for Unified SRST, Unified E-SRST, and Unified Secure SRST, see Cisco Unified SCCP and SIP SRST System Administrator Guide (All Versions).

The protocols discussed in this document are:

·         Session Initiation Protocol (SIP)

·         Skinny Client Control Protocol (SCCP)

·         Mixed Deployment (Supports both SIP and SCCP)

The platforms discussed in this document are:

·         Cisco IOS XE Autonomous mode for Cisco 4000 Series Integrated Services Routers, Cisco 1000 (ISR1100 running IOS XE), Cisco 8300 Catalyst Edge Series Platforms, and Cisco 8200 Catalyst Edge Series Platforms

·         Cisco IOS XE SD-WAN for Cisco 4000 Series Integrated Services Routers, Cisco 8300 Catalyst Edge Series, and Cisco 8200 Catalyst Edge Series Platforms

Platform and Protocol Support for Unified SRST and Unified Secure SRST Features

As the feature support is consistent across Unified SRST and Unified Secure SRST, this section provides feature support information for both these products in Table 2: Unified SRST and Unified Secure SRST Feature Support.

·         From Unified SRST Release 12.8 (Cisco IOS XE Amsterdam 17.2.1r), configuration and monitoring of Unified SRST using NetConf and RESTConf Yang models is supported in both Controller (SD-WAN) and Autonomous modes.

·         From Unified SRST Release 12.6 (Cisco IOS XE Gibraltar 16.11.1a), support is introduced for SNMP version 3 (SNMPv3) and toll fraud prevention for line-side SIP.  Unified SRST 12.6 and later releases do not support certain CLI commands configured under call-manager-fallback configuration mode to enhance security. For more information, see Cisco Unified SCCP and SIP SRST System Administrator Guide (All Versions).   

·         All features listed as supported for Unified SRST are also supported for Unified Secure SRST.

·         If a feature is supported for both SIP and SCCP phones, then mixed deployment is supported on that platform.

Platform and Protocol Support for Unified E-SRST Features

This section provides feature support information specific to Cisco Unified Enhanced Survivable Remote Site Telephony (Unified E-SRST). In comparison to Unified SRST and Unified Secure SRST, Unified E-SRST provides support for features such as Shared Line, BLF, Video, and Voice Hunt Group feature support.

Note:

·         If a feature is supported for both SIP and SCCP phones, then mixed deployment is supported on that platform.

·         Unified E-SRST is not supported for IOS XE Controller (SD-WAN) mode.

·         From Unified E-SRST Release 12.6 (Cisco IOS XE Gibraltar 16.11.1a), support is introduced for toll fraud prevention on Line Side SIP of Unified E-SRST.

For information on feature specific support for Unified E-SRST across platforms and protocols, see Table 3: Unified E-SRST Feature Support.
