Hello Vinney,
As Nipun mentioned, we highly recommend to use the SIP protocol to configure trunks, since H.323 is not longer receiving any new features or development.
Referring to the CUCM SRND:
"While H.323 trunks are still supported, SIP trunks are the recommended trunk type for Unified Communication deployments because SIP trunks provide additional features and functionality not available with H.323 trunks."
I recommend you to check the following SRND and the System Configuration guide for more details (taken out of CUCM version 11):
Cisco Collaboration System 11.x Solution Reference Network Designs (SRND)
Chapter: Cisco Unified CM Trunks
https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/srnd/collab11/collab11/trunks.html
System Configuration Guide for Cisco Unified Communications Manager, Release 11.5(1)
Chapter: Configure SIP Trunks
Process is the same for 10.5.
Regards!
Ivan
