This command sets or gets the PRI numbering plan. 

prinumberingplan isdn 

This screen is only accessible if you have a PRI network interface 
connected to your system.

With this parameter, the numbering plan is identified to 
the upstream switch as ISDN, and the number type, 
which is either national or international, is determined 
from the dialed phone number. If the dialed phone 
number starts with the international dialing prefix that 
is currently selected, the type is set to the international 
and the prefix is removed from the number before the 
number is sent to the upstream switch. Otherwise, the 
number is marked as national and passed to the 
upstream switch without modification.

This is the default selection. With this parameter, the 
numbering plan and number type are sent to the 
upstream as unknown, and the dialed phone number is 
sent without notification. The “unknown” parameter is 
preferred and should work with all properly configured 
PBXs and with most telephone company switches. A 
notable exception in North America is an ATT 5ESS 
switch, which is provisioned with Accunet, or an ATT 
4ESS switch. For these switches, set the numbering type 
to ISDN.

Returns the current setting.
