You must integrate a third-party H.323 system with your existing Cisco Unified Communications Manager cluster. When you create an H.323 trunk from the cluster, calls from the cluster to the third-party H.323 system are failing.

Which two approaches reduce the call setup time from Cisco Unified Communications Manager to the third-party H.323 device?

A.	Implement a software MTP.
B.	Implement a hardware MTP.
