I have SIP SRST working and the config has been confirmed good, however we are still having this problem.
Lack of system message (idle prompt) display on CISCO 9951 SIP phone in SRST mode on Communications Manager 7.1 using SRST 8.1 IOS.
Has anyone had luck displaying the SRST message on the supported 9951 CISCO phone?
When I do a sh voice register global, my srst system message does show up but will not display on the phone.
Thanks

The problem is that the 99xx phones currently have a limitation that prevents the message to be displayed.
These phones are not actually supported on CME so the features available are limited.

Support on SRST, Unified CME, and Unified CME as SRST
The Cisco Unified IP Phones 8961, 9951, and 9971 may fail-over to Survivable Remote Site Telephony (SRST) if WAN connectivity with the Unified CM cluster is lost. However, the set of available features is much smaller in SRST mode than when the phone is registered to Unified CM.
There currently is no support for these phones in Cisco Unified Communications Manager Express (Unified CME) or in Unified CME as SRST.

Thanks for the info!
Do you have a rough idea when they will be supported in CME?

9951 phones will be supported in CUCME 8.5 and it is releasing end of the month with IOS 15.1(3)T
