Re: CME & SRST

Yes it can.

However it has some restrictions...

Restrictions for SRST Fallback Support

•The call-manager-fallback command, which is used to configure Cisco Unified SRST, cannot be used on a router that is configured for Cisco Unified CME.

•The telephony-service setup command and auto assign command must not be enabled on a Cisco Unified CME router configured for SRST fallback mode. If you used the telephony-service setup command before configuring the router for SRST fallback support, you must remove any unwanted ephone directory numbers created by the setup process.

•The number of phones that fall back to a Cisco Unified CME router in SRST mode cannot exceed the maximum number of phones that is supported by the router. To find the maximum number of phones for a particular router and Cisco Unified CME version, see the appropriate Cisco CME Supported Firmware, Platforms, Memory, and Voice Products document at http://www.cisco.com/en/US/products/sw/voicesw/ps4625/products_device_support_tables_list.html.
