Kazoo provides a basic facility to load a rate-deck into the system for the purpose of rating each call. The rate is only utilized if the system determines the caller does not have any flat-rate services available for the number being dialed.

  1. How to load the rate deck

  2. How to test the rate deck (if possible)

  3. How to check our costs vs. retail costs

  4. How to make sure the rating module is loaded / running / being utilized

  5. Info dump to later be cleaned up

Call Rating is handled by the HotOrNot application. When it starts up for the first time, it will create a database called “Ratedeck” and load an initial rate document for US-domestic calls. That document looks like:

{ _id : US-1, direction: [ inbound, outbound ], 
pvt_internal_rate_cost : 0.01,   
iso_country_code: US, options: [ ],   
prefix: 1,   
rate_cost: 0.02,   
rate_increment: 60,   
rate_minimum: 60,   
rate_name: US-1,  
rate_surcharge: 0.00,  
routes: [^0111(\\d{10})$, ^\\+1(\\d{10})$],   
pvt_type: rate


Create your own rate document

_id is arbitrary, but we recommend using iso_country_code + prefix direction determines whether to apply the rate to an inbound or outbound call (or both).

pvt_internal_rate_cost // is what you are charged by your upstream carrier (optional)

iso_country_code // what country this rate is applicable.

options // what features does this rate apply to. You might put [Fax] for a rate, and if a fax machine is configured and has the same flag in its settings, this rate will be used.

rate_cost // how much the call will cost, per rate_increment

rate_increment // how many seconds the rate_cost applies to. So $0.02 for rate_cost and 60 for rate_increment means 2 cents per minute.

rate_minimum // how many seconds to bill for at a minimum. If a call lasts 30 seconds and rate_minimum is 60, bill it as a 60-second call.

rate_name // friendly name, eventually will be exposed in the GUI

rate_surcharge // flat rate to charge for connecting the call.

routes // list of regex to apply to the dialed DID to determine if this rate is eligible to be applied to the call.

pvt_type //

rate //

Other info

The rate chosen is based on the prefix length. So if I have two rates with routes that match the dialed DID, one with prefix ‘1’ and one with prefix ‘123’, the rate for prefix ‘123’ will be applied. The rate information is placed in the channel variables and will appear in the call’s CDR data under the Custom-Channel-Vars field.
