Description (partial)

CUCM disconnects the call after receiving 200/OK from SME.

Though the incoming INVITE is with SDP, since no 180 Ringing is sent in the Outgoing invite, 200 OK is sent without SDP in the Outgoing Invite, Hence the call is getting disconnected.

Note:  If "run on all nodes" is enabled on the sip trunks with SIP Profile - EO and PRACK is enabled
