Do 'disp bulletin' and see if someone put the information there. U can also 'list trace' of the trunk and see what digits are being inputed and 'display trunk 'whatever and look at the later pages of the form and see if there is any info there. Course the best way is the ones already mentioned. Also u can look at an old bill.
