PSA: CID Superfecta: source-Telco_Data rendered obsolete

CID Superfecta source-Telco_Data.module has been rendered obsolete by a change at TelcoData.us. The previously free XML query interface now requires an API key, which requires a paid account costing $12.50/mo - $15/mo depending upon term.

While source-Telco_Data.module could theoretically be updated to add a user-defined API key, given the monthly cost of the rate center/state queries I don’t think too many people would be interested in subscribing solely for those queries, given that CNAM dips elsewhere range from $0.002 to $0.006 each.

TelcoData.us provides services that are well worth the subscription price. It’s too bad that there isn’t a low cost “junior” account just for rate center/state queries.

Throwing the most recent version of source-Telco_Data.module here for reference. It will be removed at some point. If anyone paying for a key want’s to update it to get it working again, let us know.
