How do you prevent dialing out and back into a switch? 1

[ss341]

It has been a while but I know you can prevent a station user from dialing 9+the local DID number and using a trunk to go to the CO and another one to come back to the switch.
My local Nxx is 426. We have the entire range 0000 - 9999.
I want to keep the call on the switch if the caller dials
9 426 xxxx. I've been trying the SDDR of the RLI.

Use Home Location Code (HLOC = 426) in LD90 and DGT (del 3 digits) in LD86.

Thanks 3tdp33ler I forgot all about HLOC
Works great.

Would this work with anti-tromboning in a networked setup?

If the outbound route was also the DID inbound route, and the path was PRI, I think it would use anti-tromboning to tear down the unnecessary call path, especially if the CO switch was a Nortel switch. Q.SIG would also help with path replacement turned on.

Another thing you could do, since you own the entire NXX, is block that prefix in LD 90. I am not sure how your BARS/NARS is set up, but if you are doing 9+4 for an outbound call, you could simply DENY 26. The only thing the digit manipulation does is redirect the call, not educate the user. If this is not an issue, continue on, but if you want the users to know WHY they don't need to call out, train them and then deny the ability for them to dial that number externally. I did that locally when we went from 7 to 10 digit dialing.

Just my $.02, but I thought it was worth mentioning.

You can also use LDID

Ld 90
REQ CHG
CUST 0
FEAT NET
TRAN AC1
TYPE NXX
NXX XXX
RLI
SDRR LDID
LDID XX - use the left-wise unique rule 34=3400 to 3499
DMI XX - DMI that deletes three digits
