I don't know many cause codes, but if I remember correctly 16 stands for normal call clearing. So there is no fault in the line but something else. Maybe you dial the destination number wrong (00N) or you send a caller ID that is not allowed.

It was working properly. I went to drink coffee and then came back and found that he was not working.

Have a look at the attached doc, it's the ISDN ETSI Standard, read from page #165 for causes list.
