Mike et al.:

I just wanted you to know that this issue has to do with the PRI dialing failures we’ve been experiencing.  (The mystery octets, as it were.)  I’m pretty sure that I’ve located the source of the extra bytes by parsing the Q931 SETUP message, specifically the called party number IE: the span, channel, and slashes from the bride app data seem to be making it into the called party number field.  The details are in jira.  I figured that although this was probably trivial for you guys to fix it would be good to have the issue on record.

P.S. – Mike, thanks for all of your time on this one.  I hope this research saves you some energy.
