So? 

The trace included two _calling number_ IEs. Actually it included two 
calling numbers, one called number nad all the ususal IEs one would 
expext. The interesting part was the two calling numbers. 

Also, q.931 is the ITU specification. It is modified by ETSI EN 300 403-1 
when used in Europe and then further by national standards. E.g. in Sweden 
on Telia's (the national incumbent's) network the ETSI directive is 
further specified by the specification LZBA 506 403/0.
