I have captured few notes from Cisco articles about IPv6 support for CME and thought to share them.
CME provide support for IPv6 for SCCP phones ONLY starting from version 8.0. The following SCCP phones and devices are supported on IPv6: 7911, 7931, 7941G, 7941GE, 7961G, 7961GE, 7970G, 7971G, 7971G-GE, 7942, 7962, 7945, 7965, 7975, SCCP analogue gateway, Xcoder, and Hardware Conference devices.
CME can run in IPv4 mode only, IPv6 mode only, or Dual-Stack (both IPv4 & IPv6).
telephony-service
ip source-address {ipv4 address | ipv6 address} port port [secondary {ipv4 address | ipv6 address}
protocol mode {ipv4 | ipv6 | dual-stack [preference {ipv4 | ipv6}]}
Example,
telephony-service
protocol mode dual-stack preference ipv6
....
ip source-address 10.10.2.1 port 2000
ip source-address 2000:A0A:201:0:F:35FF:FF2C:697D
Restrictions in IPv6

- MWI Relay & Presence Server are supported in IPv4 only
