intercluster trunk are mandatory to enable end-to-end RSVP SIP Preconditions between clusters?
(Choose two.)

B.
Set the RSVP over SIP parameter to E2E.

C.
Set the SIP Rel1XX Options parameter to Disabled.

D.
Set the SIP Rel1XX Options parameter to Send PRACK If 1xx Contains SDP.

E.
Set the SIP Rel1XX Options parameter to Send PRACK for All 1xx Messages.

F.

Explanation:
Each Unified Communications Manager cluster and Unified CME should have the
same configuration information. For example, Application ID should be the same on each Unified
Communications Manager cluster and Unified CME. RSVP Service parameters should be the
same on each Unified Communications Manager cluster.
