Summary:                    Incorrect parsing of Bearer capablility IE
Description: 
The parsing of the Bearer Capability Information Element in Q.931 SETUP
messages has a number of issues; in fact, its implementation differs so
wildly from the spec that it's hard to even point at individual problems.

Hopefully I'll be able to attach some patches once I've submitted this
bug...

I second richvdh's answer. ISDN explicitly uses UL1/2/3 (defined in Q.931
and EuroISDN). Long time ago (http://bugs.digium.com/view.php?id=5#2 years) the
questionable code was not in
libpri at all.

IMO this line is a bug (or was dealing with a buggy switch)
