It also depends on whether your telco provider will permit that. They may not allow what would look like calling party number spoofing. Some will only permit it if you provide a redirecting party in the outbound leg to your cell phone. Configuration is CUCM is one thing, getting your telco provider to play nice is another thing all together.
