All Cisco applications that can terminate voice media support IPv4 only. For these applications, if a call is extended from an IPv6-only device to the IPv4-only application, Cisco Unified Communications Manager (Unified CM) inserts a media termination point (MTP) to convert the voice media from IPv6 to IPv4, as shown in Figure 11-1.
