directed call pickup not working

I've setup a feature code to use directed call pickup. the code is 3 digits at present, 784. These are 3 digit extensions.

Am I right in that the feature codelength should be 3?

101 is ringing, I'm trying to dial the feature code from 106, a test extension.

response from CLI:

-- Called 101-Prasad
