Standard Local Route Groups number globalization localization

Someday I'll turn this into volume II of Cisco CUCM number plan globalization localization normalization - volume 1 - incoming caller ID CLID. 

Or maybe I won't.

At this point, it's the rough notes regarding slimming down the average CUCM database and simplifying administration by using Standard Local Route Groups and number globalization / normalization.

Before:

Location1 Phone
    Location1 Device_CSS
        Location1 PSTN_PT
            Location1 9.1[2-9]XX[2-9]XXXXXX RP
            Location1 9.[2-9]XXXXXX RP
        Location1 RL
            Location1 RG
                Location1 Gateway
               
Location2 Phone
    Location2 Device_CSS
        Location2 PSTN_PT
            Location2 9.1[2-9]XX[2-9]XXXXXX RP
            Location2 9.[2-9]XXXXXX RP
        Location2 RL
            Location2 RG
                Location2 Gateway

2  or more locations means:
    2 or more Site specific device CSS to contain site specific PTs
    2 or more Site specific PTs to contain site specific patterns
    2 or more Site specific RP to route to site specific RL (assume no COR or generic blocked patterns on DN CSS)
    2 or more Site specific RL to route to site specific RG
    2 or more Site specific RG to route to site specific GW
    2 or more Site specific GW
   
After:

Location1 Phone
    All Location Device_CSS
        All Location PSTN_PT
            All Location 9.1[2-9]XX[2-9]XXXXXX PreDot Prefix+ TPattern
            All Location 9.[2-9]XXXXXX PreDot Prefix+ TPattern        
            All Location \+.! RP
        All Location RL
            Standard Local Route Group
                Location 1 RG
                    Location1 Gateway
                        Location1 \+.! PReDot CalledPTP

Location2 Phone
    All Location Device_CSS
        All Location PSTN_PT

                        Location1 \+.! PReDot CalledPTP
                       
2 or more locations means
    1 Generic Device CSS to contain generic PT
    1 Generic PT to contain generic TPs and RP
    1 Generic RP to route to single generic RL
    1 Generic RL to reference Standard Local Route Group
    2  or more Site Specific RG defined as Standard Local Route Group in Device Pool
