Well, PCadach and I were talking today, and it looks like there is a 
problem (with channel_id IE) related possibly to bristuff's changes.  
There did not appear to be a problem (or discrepancy) between 
ECMA-143's specification for bearer capability and Q.931.  So if there 
is something else that we might not have noticed... feel free to point 
it out.  Otherwise, quit gloating over it and be quiet.  For all the 
emails you have written in this thread, you could have very easily told 
us what you noticed.
