[cisco-voip] 911 operator gets billing number instead of DID

Fri Jan 8 11:18:42 EST 2010

I get the concepts, and I like the way it works, we just get a lot of MAC's for switch ports, and don't want to add another step for a low level technician to do (nor would I really want them in CER).

it's pretty easy once you get the concepts.

each switch port is put in a ERL.  That ERL is assigned a ELIN.  the ELIN is then updated to your PS ALI DB provider.  then when ever the phone is plugged into that switch port it uses the correct ELIN that has the correct location for the PSAP.

Our environment is very dynamic, and we couldn't find a way to automate updating switch ports in CER. We can, however, update the ALI for stations automatically (as long as we know about the move) so it's what we are currently doing. Of course, we have to be very strict on our "you can't move it yourself" policy. We'd like to deploy CER, just need to figure out the automation thing.

Wouldn't this requirement justify Emergency Responder or can it be satisfied simply by sending per-station CID?

For instance, our trunk group is in a single location, but our campus has many different address's (different buildings). Additionally, we are required by law to give room numbers due to the size of the buildings.

Yeah, I get that part. Just wasn't sure why you would want unique numbers displayed for a trunk group assigned to a single location. Jason mentioned call back and I think the carrier should alert the customer up front how they provision for 911 and if the customer wants unique DID's they can tell their provider.  I do know the carriers have to pay for every DID loaded in ALI, so cost also plays a factor for the carriers.

If all of your phones are at that address it's not a problem.  If your phones are spread across multiple remote locations across town or across the country you need to send the DID so that call can be tied to an address.

Most carriers use the BTN for 911 if you are trunking. Why would you need every DID to be uniquely displayed to the PSAP?

If you can't get Quest to block the BTN and just pass the DIDs you could pass your 911 traffic to a 3rd party E911 provider.

I can't speak for your provider, but here in Calgary (Canada), by default the provider will only send the BTN to the 911 operators.  Providers only create ALI records for the BTN, so if we want to send our DIDs on 911 calls we will have to submit an ALI record for every DID.

I have all that set up, and like I said it only happens when we call 911. At one point it was working to where the 911 operator did see our DID as you're explaining below, something must have changed on the Qwest side or the 911 side; I have the feeling that even if I specified a different number on the route list detail config the result would be the same because we're passing the correct info out.

You said the Magic Word - Qwest!  Qwest will override what you send out.  Not sure what version of Call Manager you're on but for locations that just want a single caller ID for that location, we put the number under the Calling Party Transform Mask in the Route List Detail Configuration section.  We have a couple of locations that want the individual DIDs to go out so we configure that under External Phone Number Mask on the line appearance on the individual phones.

Hi all, we are having an issue with our outgoing calls to 911 to where the operator sees our trunk billing number instead of our DID number. I can watch the call going out through my mgcp gateway to Qwest and I see the correct DID under Calling Party Number and if we call the 911 supervisor or anybody else our DID shows up correctly just not to 911. Has anyone seen this before? Is anyone in my area having the same issue with the same setup? Scott?  ;-)
TIA.
