I have seen threads regarding this error. the solutions said to make sure the call buttons are programmed. Well.....they are. I have a digital set (DS 5014D)that displays the CBT error along with a fast busy when trying to dial out. I tried to display the station data by entereing transfer + 108 and received Invalid Data Begin Again.
So... I have an extension which is not located anywhere. I can't find the prot that it was on. Like I said, there are call keys assigned. I am using a 7400. Any help would be appreciated.


Thanks,
Scott
