This is a normal thing that can happen when doing B-channel selection
as a part of the call setup process.  If one side disagrees with the
initial choice for B-channel, the other side can request that it be
moved in the reply.  It's more likely to happen on busy PRIs with
bidirectional (ingress and egress) traffic.

Hope that helps!
