I SUSPECT that ISN dialing needs to be directly and specifically supported in 
the dial plan, because:

if a third party, dials a DID*ITAD, and that DID isn't local to the sipx 
server, and it matches one of the 'normal' dial plans, the call will be 
redirected to the ITSP.

I think you can mitigate this by not using wildcard ISN DNS, or restrict it.

an example:  anyone with ISN outbound dialing enabled:  this should work: (will 
get our AA)

ISN: 5000*1300

(our ITAD is 1300)

HOWEVER, I just dialed (mycell phone)*1300 from the office, and it went out the 
ITSP.

Heh...  What is the problem?

You dialed, from your office phone, XXX XXX XXXX *1300.  It is parsed as an ISN 
call, the mapping is processed, and the call is presented to your proxy again 
as a call to XXX XXX XXXX.  That number is processed as an outgoing call and 
checked for outgoing call permission -- which the call has, since you dialed it 
from your office phone.  So the call is sent to your ITSP.

(Permissions do not control what the dialed number *means*, but they do control 
whether the caller is permitted to carry out a call with that meaning.)
