[cisco-voip] Route Filters

[Lelio Fulgenzi]

For what it's worth, here's a summary I came up with. TAC seemed to agree with all this. Based on what the web page shows, but since I was new to this, I wanted to make sure I new which fields affected what type of dialing. The transit network escape information was a new one for me too.

AREA-CODE                 : Long Distance Calling (refers to the NXX in 1+NXX+XXX+XXXX)
COUNTRY-CODE              : International Calling (depends on digits dialed)
END-OF-DIALING            : *All classes* (typically #)
INTERNATIONAL-ACCESS      : International Calling (refers to '01')
INTERNATIONAL-DIRECT-DIAL : International Calling (refers to the 2nd 1 in 011)
INTERNATIONAL-OPERATOR    : International Calling (refers to the 2nd 0 in 010)
                          : In Canada, we simply drop the 2nd 1 for Op.Asst.
LOCAL-AREA-CODE           : Local Calling (refers to the area code in an LD number)
LOCAL-DIRECT-DIAL         : Local Calling (refers to the '1' in 1+local number)
LOCAL-OPERATOR            : Local Calling (refers to the '0' in 0+local number)
LONG-DISTANCE-DIRECT-DIAL : Long Distance Calling (refers to the '1' in 1+NXX+XXX+XXXX)
LONG-DISTANCE-OPERATOR    : Long Distance Calling (refers to the '0' in 0+NXX+XXX+XXXX)
NATIONAL-NUMBER           : International Calling (depends on digits dialed)
OFFICE-CODE               : *Local & Long Distance Calling* (refers to the XXX)
SATELLITE-SERVICE         : International Calling (depends on digits dialed)
SERVICE                   : Service Calling (411, 711, etc)
SUBSCRIBER                : *Local & Long Distance Calling* (refers to the XXXX)
TRANSIT-NETWORK           : *Transit Network Escape Calling* (refers to the 4digit code)
TRANSIT-NETWORK-ESCAPE    : *Transit Network Escape Calling* (refers to the 101)

Regarding TRANSIT-NETWORK & TRANSIT-NETWORK-ESCAPE - this is used when dealing with what I can 10-10 dialing. Well, that's how they're advertised. For example, yak communications advertises 10-10-925 so they will bill you cheaper long distance. In actuality, what you're dialing is 101-0925: 101 for the transit escape and 0925 for yak communications.

All the networks are listed here at the NANPA site and are referred to as Carrier Identification Codes.

  As mentioned, route filters only work with the @ macros.  The @ macro  
  includes all the different dialing types in the North American  
  Numbering Plan (NANP).   The idea is you have multiple 9.@ route  
  patterns with different route filters.  The filters allow you to deny  
  things like 411, 900 numbers, etc while allowing normal local, long  
  distance, etc calls to go out.

  I can't begin to list what each of the items in the route filter  
  configuration page are.  Check out the link below for more info.  It's  
  written for CM 3.3 but should pretty much hold true for any version.
