Say you install the softphone on one computer, but then the user gets a new computer. You uninstall it from the old computer and reinstall it on the new computer. The CM still shows the IP of the old computer and registration on the softphone is hung up. Any ideas what I did wrong? Thanks.
Yes Since the IP communicator is unistalled from the old computer delete the current configuration in callamanger.
And then configure the IP communicator with the new MAC.
Have you changed the MAC address in the IP Communicator config on CUCM to the NIC of the new PC?
