Invalid PTMP redirecting signaling as TE towards NT.

Browse Source 
* The PTMP redirection signaling (NOTIFY redirection number and
notification code, SETUP redirecting number) is also sent in PTMP/TE mode.
It should only apply in PTMP/NT mode.  The call setup proceeds but the
network (Deutsche Telekom) reacts with ugly ISDN STATUS messages.

* Don't send the redirecting number ie when PTP is also sending the
DivertingLegInformation2 facility.  The redirecting number ie is redundant
and the network (Deutsche Telekom) complains about it.
