No dial plan rule matched


hi, i have a UCM installed and setup group pickup for user, so they can pickup the ringing phone from their desk, if the other person is not around for the call but every time the user try to dial **XXXX (x = Ext. No)
the screen on the phone is showing “no dial plan rule matched” can someone be able to tell me what am i missing on the group pickup setting?

thank you
