Core Issue
Unable to change the IP Address on the Cisco CallManager Express and the Cisco Unity Express
Resolution
The IP Address can be changed on the Cisco CallManager Express with this command:
ip source-address ip-address [port [port]]
Refer to the Activating IP Connectivity to Cisco Unity Express Software section of Installing Cisco Unity Express Software in order to change the IP Address of the service-module for the Cisco Unity Express.
Note: Before the IP Address is changed, make sure these are configured per the specific network requirements:
- the DHCP pool scope
- the static route to the service-module
- the IP Address of the service-module on the various dial-peers
Refer to Cisco Unified CallManager Express Solution Reference Network Design Guide for more information.
