BR (should say “end of list”. If there are other Dst codes such as “.” or “9.” delete them)
Go back to Dst Code:9
TR (normal 001) If it is 000 or anything other than 001, change to 001
TR AbsorbLength:ALL (or change to ALL)
By setting to AbsorbLength:All this will override Dialing Plan limitations which could limit local area codes, 7vs10 digit dialing or long distance dialing
In some situations calls may fail to complete or dial correctly on a PRI. Someone may have set dialing rules in the past causing issues for numbers such as 404-351-4114 in which the “411” is seen by the phone system as someone dialing “information” and the system immediately sends out the call without waiting for the last “4” If the Absorb Length All is set up Public Network DN Lengths are not necessary since any call on PRI-A will be sent to the PRI out and out to the carrier.
Goto System Programming, Dialing Plan, Public Network, Pub DN Lengths, scroll using the bottom right button to “411” and remove it. Then make a test call to the number having a problem and make sure it will dial correctly, also call 411 information and make sure that goes through as well.

Before Routes and destination codes will work, remove line pool and external access codes under Line Programming.
Under Services, Route Services and Router, you can use Route 000 and set it to pool A vs PRI-A if you don’t have PRI installed. Leave the External Number blank unless you have carrier access codes that need to be dialed.
For destination codes, typically program “9, Any” and set normal and night to absorb 1 will allow all calls to route out correctly. At O’K Duluth we had a DNIS number that started with “96” which was causing “9, Any” not to work for calls starting with 6. In this case we had to program destination codes 91any, 92any, 93any, 94any, 95any, 96any, 97any, 98any, 99any and 90any. This then allowed calls to route out correctly for 770, 404 and 678 numbers.
Last check the Public DN lengths for prefix default and make sure it is set to 10 vs 7 for Atlanta 10 digit dialing, 0=11, 00=12, 01=17, 011=18, 1=11, 411=3 and 911=3
