this is mainly fxo port which is configured. but physically their is no phone is connected. check it..

and if you config. phone in router but not in cucm.. if so, delete conf. and try to conf. in CUCM

I think the Problem is in the phones config.

1. Check what phone model you have 7941G-GE or 7941.

2. Check the model configured on CUCM

If you have selected the wrong phone model  during configuration, the Phone will try to autoregister, because you have disabled autoregister the shown error massage will pop up
