The Q.932 part of that and invalid protocol profile field shouldn't be 
your problem.  It looks like the switch is rejecting it for this reason:

< Protocol Discriminator: Q.931 (8)  len=8
< Call Ref: len= 1 (reference 23/0x17) (Originator)
< Message type: RELEASE (77)
< [08 02 81 e4]
< Cause (len= 4) [ Ext: 1  Coding: CCITT (ITU) standard (0) 0: 0   Location:
Private network serving the local user (1)
<                  Ext: 1  Cause: Invalid information element contents
(100), class = Protocol Error (6) ]


Invalid information element contents.  You need to figure out what the 
switch doesn't seem to be liking.  Looks like it doesn't like the way 
one of the IEs is coded.
