Cisco Unified SRST/E-SRST 10.5 Supported Firmware, Platforms, Memory, and Voice Products

About Cisco Unified SRST and E-SRST 10.5

Documentation

See Cisco Unified SRST.

Secure SRST

See Setting Up Secure SRST.  Cisco Unified Communications Manager 4.1(2) or a later version is required for secure Cisco Unified SRST. Secure E-SRST is not supported.

Secure SRST Specifications

See the  Media and Signaling Authentication and Encryption Feature for Cisco IOS MGCP Gateways for complete specifications.

Cisco IOS Compatibility

To see a list of Cisco IOS releases that support Cisco Unified SRST, see the Cisco Unifed CME Compatibility Matrix. Cisco Unified SRST is compatible with the same Cisco IOS releases as Cisco Unified CME.

Downloads

To download Cisco Unified SRST software, go to Technical Support Software Download for Cisco Unified CME and Cisco Unified SRST.

Cisco Unified SRST supports Cisco Unified Communications Manager firmware. For more information, see the CiscoUnified Communications Manager Compatibility Matrix.

You can download firmware files from Technical Support Software Center for Voice Software.

* Memory recommendations and maximum numbers of IP phones are for common Cisco SRST configurations only. Systems with large numbers of phones and complex configurations may not work on all platforms and can require additional memory or a higher performance platform.

** The Maximum Total IP Phones can be split between SCCP and SIP phones as long as the maximum total of IP phones is not exceeded.

**** SRST 880 is natively supported by CUCM 6.13 and 7.1.

To get the same number of SIP IP phones support as SCCP IP Phones, SRST 4.1 in 12.4(15)T is required.
