I suggest you check the CME compatibility matrix.  Your IOS version probably doesn't support the CME version that would support the 6941 phones.  Looks like you might have been typing quickly, but if you have 26 CME routers and they are all working normally besides this one, I suggest maybe you check the IOS version the other other routers are running.

Hope this helps let me know.

Thanks for help Gregory.

The problem was with IOS version. I update it to 15.2.4 and after that everythink ok.
