Ahhh..... so you have an interconnect switch then I take it!

You need to set the q931.c value - PRES_ALLOWED_NETWORK_NUMBER which has a
value of '3'. I think, although I've never tried this, you can actually call
the application CallingPres with the value of 3 before making an outbound
call. CallingPres(3) I think should do it - someone else might be able to
advise better.
