Hello,

You don;t need a module or external card to enable SRST on your Cisco CUBE (CME).

You may check the following Post from Community https://community.cisco.com/t5/collaboration-voice-and-video/how-to-implement-cisco-unified-srst-and-mgcp-fallback/ta-p/3113024 

and the Cisco Configuration Guide 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_overview.html

I hope these help

Thank you, is there any type of license to enable SRST feature?

I believe you should check for SRST-EP License
