I think it's a terminology difference, and I may not have been clear on which the OP was asking about. The LERG, or Local Exchange Routing Guide, contains information that defines LATAs, Rate Centers, localities, Numbering Plans, and exchange/LRN routing data among other things. I think it is a stretch to say that this does not count as information pertinent to a "local calling database". Local calling areas (which to me refers to what calls are classified as local and are "free" vs. which are LD or more generally "toll" and are charged usage for) are a billing concept usually based on "rating" calls that can differ from carrier to carrier and plan to plan. Telcordia talks about this here http://www.trainfo.com/products_services/tra/catalog_details.html and http://www.trainfo.com/products_services/tra/downloads/tra_catalog.pdf. -Scott -----Original Message----- From: Jed Stafford [mailto:jedsta at gmail.com] Sent: Wednesday, September 08, 2010 5:42 PM To: Scott Berkman Cc: Corey Edwards; <voiceops at voiceops.org> Subject: Re: [VoiceOps] local calling database To help clarify, the LERG does not contain local routing information. LCADS does which Telcordia sells but I've heard much better things about the KFR data from people who have compared both. As a point of interest our Qwest team pointed us to localcallingguide as the resource they wanted us to use for local calling areas.

Currently I'm using some Perl scripts tied to localcallingguide.com's XML API to build a local calling database, and that seems to be working great, but in the spirit of due diligence I'm looking for feedback about other local calling databases out there, both free and commercial.
On or off list replies appreciated.
