asterisk users - May 2007 - PRI problem, pri_fixup_principle: Call specified, but not found?

Hi,
in a PRI setup, the receiving side is changing the B channel at
proceeding. It seems this sometimes breaks some logic
(pri_fixup_principle) and then the hangup kind of breaks, release is not
answered and a restart cycle is triggered (by remote side).

Anyone can help me debug this ? I've seen many posts with simmilar
issues but no answer/solution.

This is happening on Asterisk 1.2.16 + libpri 1.2.4 on a sangoma A104D.
On a general side, where can I find a document (other than sources :)
to start digging where the Zap->pri mapping is done and how,
or at leaset what pri_fixup_principle is supposed to do...

TIA,

Please post the layer 3 trace for this call scenario so that members of this
forum can help you debug your problem.
