Note
When Cisco 4000 Series Integrated Services Router is configured to use Network Address Translation (NAT) along with Unified CME 10.5 and later releases, we recommend that the ip nat pool overload command is configured to ensure that IP phones (applicable only for SIP Phones) successfully register on Unified CME. Also, ensure that the source IP address defined for Unified CME using the command source-address is excluded from the IP pool used for NAT.
