Problem with ESA and dialing 9,911 on PRI Trunks

[viper222]

I have read the posts about ESA in LD 24 and have found out that I think I am stuck without a solution but please point me in the right direction if possible.

We need to be able to dial 9,911 and get out to 911 operators. The problem is that in LD 24 if I put 9911 as my ESDN, no matter what I put for DDGT it still sends 9911 to the PSTN and we get an invalid call. I need to strip the 9 of course and I read that the DDGT field only functions on CAMA trunks, and well, I don't have that since I am using PRI Trunks. The customer HAS TO HAVE the ESA setup so they get the fancy prints and what not that the ESA number provides. Well, Right now I have it in as a SPN and routing it out but I need to get the ESA working again. The customer SWEARS that about 5 months ago it worked this way, dialing 9.911 and it routing out to the PSTN to the emergency services AND doing all that the ESA does. Is it possible that their local provider used to accept 9911 and sent it correctly and they stopped?? No one can remember doing anything that would have caused this but IS IT POSSIBLE to use ESA with 9911 and have it only send 911 to the PSTN over PRI, if you have a print out thank you very much......

Right now I have:

TYPE ESA
CUST 0
ESDN 9911
ESRT 31 (This is my main outbound PRI Route (3) T-1's
DDGT 911 (Also tried 9911 but I think that CAMA Trunk thing)
DFCL 3818800
OSDN 6911

If you have CDP you can send 9911 to 911 as a local termination.

 

[viper222]

I do not have CDP BUT as far as I can tell the ESA number (ESDN) overrides all other programming.

try and program ESDN as 911 and make an spn for 9911 to lctl in the rlb. Then either 9911 or 911 will be recognized. Don't forget to check your CLID table for the ESA_ programming to send out correct CLID to E911.

 

[viper222]

I actually set it up that way this morning so 911 is reachable but the customer wants to get the ESA prints and notifications for both 911 and 9911 since many people will dial 9911.

 

[mluckie1]

Understood. you can setup an RLI and at the LCTL prompt answer Yes. This will keep it local to the switch.

 

[viper222]

The ESRT prompt asks for a route not a Route List, so how do I make it point to a Route List Index or are you saying to build a SPN of 911 and point it to a RLI that has LCTL YES so it will then route the stripped 911 to the ESA part? I may be overthinking this.

Try this, make your ESDN 911. In your route 31 install a dummy DMI ( one that doesn't do anything.). Now try 9911.

 

[mluckie1]

You would build 911 in ac1, LD 90. The RLI is built in ld 86.

 

[Pete87]

Not if your using ESA.

 

[Pete87]

Sorry, hit the submit by mistake. The RLI is built in LD86, but 911 is done in ld 24 as ESDN.

 

[Pete87]

Sorry guys, I'm new at this. Just read somthing else. Viper, your right about the RLI. Once you build an ESA block, you are telling the system that this is my emergency number and I don't care about TGAR's or NCOS's or anything else just send it. At that point the ESA block just wants to know what route to use.As a fall back if your primary route fails, you can program a STEP route in your primary route block.
