[cisco-voip] PSAP sees Billing Telephone Number, not DID associated with phone

[Tobias Goldstone (TOGOL)]

Yes you should be able to pass all DID's through to the PSAP.  ATT doesn't mask on their PRIs.

You will however need register those DIDs with the PSAP or they won't get any ALI information.

Hi,

We purchased a PRI (Cisco 2851 Gateway) from ATT, and while testing I find out the PSAP only sees the BTN when I make a test 911 call.  I called the ATT trouble line and they told me they never block the calling number and that it is configurable on each PBX.

Are they correct and is it a setting I can change to allow the PSAP to see individual DIDs?

CUCM 7.02
2851 MGCP
NM-4VWIC-MBRB / VWIC2-1MFT-T1E1-T1



Thanks,

John
