Configuring SIP TLS between CUCM and Voice Gateway

Hi,
I have a setup like shown below:
IPPhone >>CUCM>>(SIP Trunk)>>Voice Gateway(ISR4351)--PSTN(ISDN PRI)
Now the CUCM is working in mixed mode and Internal calls are using SRTP. We have only one internal Third-Party CA as a Root CA and there is no Subordinate CA.
The integration between CUCM and Voice Gateway is SIP. Now we want to configure SIP over TLS between CUCM and Voice Gateway. 
I have been referring this document https://www.cisco.com/c/en/us/support/docs/unified-communications/unified-border-element/200614-Configure-and-Troubleshoot-Enterprise-CA.html
I am confused after reading above document, as it is mentioning about Subordinate CA. Since we have only one CA (Root), What difference should I bring into my configuration?
My CUCM Version : 11.5.1.15900-18

 

Regards,

Shinas
