Could be a bug in chan_ss7 then, or the other end doing something strange.

If possible, you should obtain an ISUP dump when this happens and send to the
list. See http://voip-info.org/wiki/index.php?page=Asterisk+ss7+commands for
one way of doing this, something like

    ss7 dump start <file> both msu
    <repeat problem>
    ss7 dump stop
