    1. Avaya ARS Strategy Guide ARS - Automatic Route Selection Strategy Overview

    2. Ernest G. Wilson II 2006

    3. Ernest G. Wilson II 2006 ARS Decisions 5 Specific Conditions Delaware (302) “Local NXX” Calling Special (610, 484, 410) NNX Calling Long Distance and Toll Free Calling Internal Numbers (Known NXX 5 digit) 911 Calling

    4. Ernest G. Wilson II 2006 Delaware (302) “Local NXX” Calling Every site will have an ARS Table Each site will have specific Route Patterns All sites will try to utilize the main default “all” table to reduce duplicated values Each Pattern will obey the “Golden Rules” (Best Cost / Best Choice Routing)

    5. Ernest G. Wilson II 2006 Special (610, 484, 410) NXX Calling Take advantage of special locations Some locations can cross border lines Route calls to special trunks if possible Reduce toll charges if possible

    6. Ernest G. Wilson II 2006 Long Distance and Toll Free Calling Create Route Patterns for LD Prefer site local trunks first Overflow trunks as per “Golden Rules” More MPLS hops not desirable International calls fall under LD Route Patterns but are restricted by COR as desired

    7. Ernest G. Wilson II 2006 DHSS Internal Numbers (255-9 etc.) Convert to 5 Digit when possible Digit Conversion is NOT an option at this time due to ESS Ramifications! Avoid PSTN for site to site calls

    8. Ernest G. Wilson II 2006 911 Calling Create site specific Route Patterns Create one dedicated 911 trunk per site Overflow to local trunks first Only use non-local trunks as last resort Consider CAMA trunks and E911 RedSky

    9. Examples UP NEXT: Actual Scenarios

    10. Ernest G. Wilson II 2006 Digit Conversion NOT possible at this time due to ESS! Example #1 – Any Avaya user dials: 9,1-302-255-9991 9,302-255-9991 9,255-9991 59991 Automatically use the 5 digit internal system because 255 is Campus Keep all possible 5 digit calls in network from any location to any location

    11. Ernest G. Wilson II 2006 Route Patterns Example #2 – Any Avaya user dials: 9,1-302-239-9999 9,302-239-9999 9,239-9999 Automatically use the Campus trunks first because 239 is local to Campus Always use a trunk local to the NXX first (if possible)

    12. Ernest G. Wilson II 2006 Route Patterns Example #3 – A Milford Walnut Street Avaya user dials: 9,1-302-424-1080 9,302-424-1080 9,424-1080 Automatically use the Walnut Street trunks first because 424 is local to Walnut. If the Walnut Street trunks are full, try using Windsor’s trunks next Continue in order trying more local trunks first, Firehouse, Causey, then Annex etc. If all local trunks are busy, then move North in order

    13. Ernest G. Wilson II 2006 Route Patterns Example #4 – A Campus Avaya user dials: 9,1-302-424-1080 9,302-424-1080 9,424-1080 Automatically use a Milford trunk making a local call before dialing long distance from Campus

    14. Ernest G. Wilson II 2006 Route Patterns Example #5 – Long Distance / Toll Free: 9,1-800-242-2121 Prefer site local trunks first Campus uses Campus trunks Milford uses Milford trunks etc. No benefit by using the MPLS network

    15. Ernest G. Wilson II 2006 Route Patterns Example #6 – Emergency 911 Calls: Use the “Dedicated Site Specific 911 Trunk” first! Overflow into other site local trunks next Use remote trunks only as a last resort Remote trunks can cause 911 confusion Consider getting special CAMA trunks Consider an E911 solution like RedSky
