Kenneth,
If that's the case you can use a range of port and create a NAT using your outside interface IP.
object network CUCM_Private
  host 10.10.10.10
object service Range_1024_65535
service udp source range 1024 65535
object service SIP_range
service tcp source range 5060 5061
nat (inside,outside) source static CUCM_Private interface service Range_1024_65535 Range_1024_65535
nat (inside,outside) source static CUCM_Private interface service SIP_range SIP_range
access-list outside_access_in permit tcp any object CUCM_Private eq 5060
access-list outside_access_in permit tcp any object CUCM_Private eq 5061
access-list outside_access_in permit tcp any object CUCM_Private range 1024 65535
Take in consideration that I am using different IP address, please use the correponding IP's.
Hope it helps,
