This would be the SRST part from our in-house configuration template for voice gateways.

You also need to verify that the SRSR configuration in CM has an IP for both fields for IPv4.
One other thing to check, make sure that the phone can get updated configuration from CM. Once simple way to do that is to either turn on or off the web interface on the phone in the device configuration in CM and then reset the phone. If this do not change you likely have an issue with the ITL on the phone and it will not trust the changes made in CM. If this is the case you need to do a reset of security settings on the phone.
Maybe a silly question, but have you on the SRST reference in CM configured an IP in both SCCP and SIP fields?

sh call-manager-fallback Is for SCCP SRST. You need to check this for SIP SRST. Have a look at this document for details on commands used to check SRST. https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cusrst/admin/sccp_sip_srst/configuration/guide/SCCP_and_SIP_SRST_Admin_Guide/srst_monitoring_and_maintaining.html
