I am trying to send 911 calls as number Plan ISDN and Type National; and only 911 calls. So I cannot globally change this setting on the PRI, I would like to keep the 'Cisco CallManager' setting on the PRI, so that when I dial 911, it knows to send my digits as ISDN National. I tried to do this using Route Filters, but that only set my Called Number as ISDN National, the calling number was still unknown.
Is there a way to tell callmanager to set my calling number to a certain type with MGCP? I assume its the equivalent of the isdn map in H323 gateways.
Please let me know.
