SRST and IP Telephony Service (aka IP Keyswitch) is now integrated into the 12.2T train, and there have been a number of features and bugfixes applied. So, depending on the platform, you are probably better off going for the latest 12.2T release. 12.2(8)T4 is the current release, and 12.2(11)T will shortly be released.
