I have deployed Callmanger 5.1 with CER 2.0, and I am sending out a 10 digit Calling Party Number set up in the CER ERL. The calls go to the PSTN through 2 PRIs setup as a MGCP gateway. PRIs setup as NI2. I have verified the Calling Party Number sent when dialing 911 thru debug q931 on the router.
Calls get answered by the PSAP, but no number (and location) is displayed at the PSAP. The ANI is seen on the Telco's PRI Switch, but is not being sent to the PSAP for ALI lookup.
Is there any configuration setting on the Callmanager MGCP gateway setup that needs to be disabled/enabled for the Telco to forward the Calling Party Number as E911 ANI?
